(upbeat music) - Hi, everyone, welcome to a third grade science lesson.

I'm Mr.

Dunlea and I teach third grade with Mrs Delaney in Tabernacle Elementary School, in Tabernacle New Jersey, which is located in Burlington County.

And today I'll be co-teaching with Dr.

Amy Williams.

- Thank you, Mr.

Dunlea.

Hi, I'm Dr.

Amy Williams and I am a general science teacher at Ocean County vocational Technical School District.

I teach juniors and seniors at the brick and Jackson's centers.

And I am located in Ocean County in New Jersey.

I'm actually a coastal ecologist which is someone who studies everything about the beaches, the plant's life, the animal life, the wind, the waves, the water, and how all moves around it interacts.

- And today we're going to take you all on a wonderful field trip, where we're going to explore a bunch of different habitats, all around Barnegat Bay.

- [Amy] We'll be looking at the different biodiversity that exists in the habitats of Barnegat Bay.

The third Barnegat Bay goes from our freshwater to our ocean.

And in between all of the areas that are called brackish or partially saltwater.

We'll see lots of different animals, lots of different plants, and also how the bay affects humans.

- [Dunlea] And in addition to that, we're also going to be able to visit an active seaport where fishermen go out every day fishermen and women go out every day and bring back a whole lot of seafood that is eaten all across the country and the state and that's called Viking village.

And then we're going to end our trip at-- - [Amy] The Barnegat lighthouse, old Barney.

It's red and white and we will get to walk all the way down the jetty to see where the ocean meets the Barnegat inlet.

And look at some tide pools and see some of the examples of different animals that have been living and using our ocean.

- So I hope you're ready for a fun and exciting day of going around Barnegat Bay and discovering all the wonderful things that are here.

Okay, young scientists.

These are the items that you're going to need; paper, something to write with a pencil or pen and something to draw with crayons or markers or colored pencils.

Go ahead and get your supplies and we'll wait.

(soft music) So where and what is Barnegat Bay?

Barnegat Bay is located in southern New Jersey in the Ocean County.

This stretch of white sand is Long Beach Island.

It's 18 miles long and half a mile wide.

Just to the north, you would find Seaside Heights.

Even further north, you would eventually find New York City.

And this whole area over here is Barnegat Bay.

That's where we'll be exploring today.

Here's a map that will help us better understand where it is.

On the right hand side of the map, you'll find the Atlantic Ocean.

And on the left side is where you'll find Barnegat Bay.

Here's another aerial photograph caught by a drone.

What I like it so much is that it has the sandy bottoms that you can see through the water.

That means that it's very shallow in those areas and where you see the darker colors is the deeper area where the boats can go so they don't run aground.

And then this little strip of sand that you see right there is called High Bar Harbor.

And that's where our trip is going to begin today.

So I mentioned that we're gonna go seining.

I want everyone to take their paper and the pencil or pen.

And I want you to write the word seine on one of the lines of the paper or at the top of the paper.

S-E-I-N E. And then I want you all to say seine.

Go ahead, seine.

So a seine is a fishing net that hangs vertically in the water.

One of my favorite things to do when I'm in school is to find all the different places where math can be found.

And here's one, the word vertical reminds me so much of math because it says it means going up and down.

As opposed to its partner word horizontal, which goes across.

We're gonna be making a list of some words that we're gonna learn today.

And you can go ahead and start it with this one.

After we're done making our list you can go back and choose a few other words to draw pictures to go with them.

Or you can draw a picture for all of them.

But it's your choice.

And we're gonna start the list with seine.

I wanna introduce you to a friend of mine.

His name is Kyle Gronostajski.

- Kyle Gronostajski I'm executive director of Alliance for Living Ocean an environmental nonprofit on Long Beach Island.

We've been around since 1987.

And we like to do a lot of education and outreach programs.

And we are involved in exciting things in the beach.

Do beach clean ups and different things like that.

- [Dunlea] So you're looking out at Barnegat Bay, and the Barnegat Lighthouse.

And that's the seining net, lying there on the beach.

And you can see the floaters, the weight.

Little barbs at the top and there's weights on the opposite side.

- In waters the seine net is easy for us to use.

At what area we catch lots of things.

This one is about 15 feet long and 4 inches This is what we use to drag through the water.

There's floats on the top and weights on the bottom that keep it open.

Our goal is to drag it through the water as wide as possible.

Scooping everything that we can up to the bottom and scooping it out of water.

- [Dunlea] So Kyle and Dr.

Amy Williams are gonna do a wide scoop as they walk out into the bay, keeping it straight and taut as tight as they can.

Nothing gets harmed in the process.

- Make sure that we quickly get everything into our bucket or right back into the bay.

Everything we'll catch will survive.

And go right back at home,we're done Our goal is to observe it.

To take a look at what unique live in the bay.

- [Dunlea] Exercise break.

Time to pretend you're seining in the bay.

So stretch out those arms, act like you're holding the net and imitate Kyle and Amy.

Wherever you are, do what they are doing.

Just pretend that you're seining in the bay.

It gets the blood flowing.

So Kyle and Amy took the net into the water and they did a nice walk all the way out into the bay.

And you could see how the net is being kept stretched out and they're scooping everything up in between them.

So they're walking parallel.

They'll never cross the lines, they're keeping those poles parallel.

And the water, I asked them I wanted to know how warm the water was They said it was around 65 degrees.

And they said it was warming up the ocean was a little bit colder because the the ocean's deeper and interacts with the currents from around the world and the current is under water river that flows.

And so then they walk back closer to the beach keeping that tight the entire time so nothing can get under or over it.

And then they bring it up onto the beach.

And then we'll go through and see what they caught and what they found.

It was a little windy on the bag.

But it was exciting and we got a lot of cool stuff to show you.

(gentle music) There is different algaes in here.

Some of it is your grass they get these kid something(murmurs) there're couple different molluscs - [Amy] I also have a comb jelly or Ctenaphore.

It actually is very hard to see right now, but it does have these little lines on it that are called bioluminescence, which is like light and it will light up in the nighttime.

- [Kyle] I know bio means life so is that part of that?

- [Amy] Yep, living life - [Kyle] very cool.

'cause when we do our biographies and genres, it's about a life picture.

Someone's life story.

- [narrator] This includes around 100 species.

Their radially symmetric body contains eight rows of comb like plates of pure cilia, that be in order for them to move through the water.

The comb rows refract light to create a rainbow display as they swim.

Some comb jellies additionally exhibit bioluminescence for the emission of light by chemical reactions.

Their body is over 95% water.

When taken out of water, they literally look like a blob of jelly.

About half of the comb jelly species feed by the use of a pair of tentacles that do not sting, but instead contains sticky cells called colloblast.

Zooplankton will stick to their tentacles, and they will try to pray into their mouth.

- [Kyle] So in this one we caught an isopod.

So isopod are pretty similar to the bugs you might actually find in your garden.

But these guys live underwater.

This is actually a really big one.

They come in a lot of different colors, there's green ones, there's tan and brown shades.

Now that's(mumbles) The color in them is gonna depend on where they live.

So if they're gonna hide out in some green algae or things like that, they're gonna want to be green for camouflage.

- [Dunlea] Oh that's cool.

And here as you can see him dancing around a little bit it's a little shrimp.

- [Dunlea] Oh, yeah!

Here is the shrimp I think it's a little-- [Amy]Kyle over there has another couple of shrimp in his container.

- [Dunlea] Wow, I didn't see them in the net when you got them.

- [Kyle] They're almost translucent.

There's so much vocabulary that's great with science and math and everything.

- [Kyle] Yeah.

- [Dunlea] Just translucent being able to see through it.

Like transparent or light goes through it.

- [Kyle] Yeah.

- [Dunlea] Check that out.

So with that, what these developments are like the shrimp that you might see in stores that are-- - [Kyle] No our shrimp around here generally gonna stay on smaller side.

Also these guys are gonna be, maybe three inches at most.

Different types of shrimp like San shrimp and crab shrimp are really big part of the food chain here.

So lots of birds and lots other fish love to eat these guys.

If you are fishing it would be great bait.

(gentle music) - [Dunlea] Scientists, get your paper and pencil and add the following words to your list.

comb jelly, shrimp, isopod and food chain.

We're going to continue to add words to our list throughout Lesson.

But those are the four sets of words that you can go ahead and add now.

And then later, as I said, you can choose which ones you'd like to draw pictures for.

I'll give you a few moments to finish your list before we move on.

(gentle music) - [Male voice] Oh here's some This is... - [Amy] Sure!

So this is really nice to actually see a shell like this, put together.

And we call these, its a clam shell but what we call them is a bivalve.

So valve being the shells and bi meaning two like a bicycle.

And so normally when We find them they've already been separated apart 'cause something ripped the mussels apart.

And they've already eaten them So you'll usually find one shell of this.

Very interesting chance to actually see them together and see how they can fit together.

Have a nice protective shell on them.

And now, I call this a clam.

But this is really the shell of a clam.

The clam is the animal that lives inside.

And the shell is kind of like our hair, our fingernails, it's part of the clam made by the clam but it's not the living part.

So even when the mussels die, we still have those pieces left over.

So We still have the shell left behind - sounds like a skeleton almost - Kind of a skeleton Yep.

- [Dunlea] And that's the-- - This is the Fazor clam and I've never seen a live one before nature.

So again, this is a bivalve.

And this is the clam that you can kinda see right there coming out.

- Oh Yeah!

- That is its foot and it is trying to move.

But that's the living organisms that created the shell around there.

So (Amy shouting) (laughing) - [Male voice] That is wild.

- So they move a little bit by propulsion, sucking stuff and moving it out and also trying to push itself along the ground.

- That is so cool, All right.

I feel like I might be stressing this one out.

- I guess so.

- So am gonna put it back in.

- [Male voice] Put it back in the water.

- [Amy] I've never seen that, that's so exciting.

(laughing) - [Kyle] So here you are, that's very, very cool.

- [Amy] Wow.

- [Kyle] So it just uses that foot to push along and dig and-- - [Amy] It has this just one big muscle and it uses to dig or push yourself along-- - [Kyle] And when it was squirting that water It was really just to trying to propel forward and move?

- [Amy] Yeah that's what I believe it was trying to do.

Now you can see it's kinda digging down, straight down.

- Oh I see - It's now going on to burry itself into the ground.

- [Kyle] So it's digging itself in and going down.

- [Amy] Sometime on the beach you can find little tiny clams Like we call them Coquina clams.

And if you put them in your hand, they'll stick out their foot to kinda tickles your hand.

- [Kyle] So-- - [Amy] Come here (mumbles) - [Kyle] I felt the crab between my toes.

Had it close to my foot.

- [Dunlea] Even I got a chance to go out seining in the bay with Dr.

Williams.

This was the very first time I've ever done it.

And I walked out and I have to tell you the water was pretty warm.

And the bottom was very soft and spongy.

And we did our loop, we did a half circle.

And it got heavier as we went through and started catching some of the the seaweed and the algae.

And we were able to make a full loop.

And it was an amazing experience.

And when we finally did lift it up, we found a bunch more of the shrimp.

And they were super difficult to catch.

I was having a really hard time and they kept jumping all around.

And when I did get one, I finally had it in my hand, it jumped out of my hand.

So you can see that they're trying there get back in the water and all these did go back in the water.

But we went through all of that algae in the sea weed.

- We also have some Ribbed Mussels living along the shoreline here.

Ribbed Mussels are another great bivalves.

They're not the type of mussel we wanna eat, but they do a really good job of filter feeding and they also do a really good job of stabilizing the shoreline.

So you'll notice the Ribbed Mussels are gonna be all along they edge where the tide comes up and down.

There are actually some that'll probably be living out of the water at lower tide.

But what they allow the marsh to do is stabilize when there's high wave action, wind events that doesn't all break off and wash away.

So they're a really important part.

- [Amy] The mussels.

And they open up.

They are filter feeders.

So they will suck water in and take little pieces out of the water to eat and so when I go towards and touch them, they actually close back up again.

- [Dunlea] And so the tide is starting to come in.

It looks like this is getting deeper.

(mumbles) - I also have here a periwinkle snail.

- [Dunlea] Here Dr.

Amy Williams found the common periwinkle snail.

Which is a small edible whelk or a sea snail.

Edible means you can eat it.

And this twisting action is called torsion.

And you can see it uses its butt to flip itself back over.

It's also the reason why their snail shells are all twisty.

The way that they're created is through that same torsion.

Here you can see what is a probing sensor.

It almost acts like an eye and it's sensing where it is.

And is looking for water which Dr.

Williams made sure she had some in her hand.

All right, scientists is that time again.

Get that pencil on paper and add razor clam, ribbed mussels and PeriWinkle snail to your lists.

And I'll give you a little while to add those groups of words.

Razor clam, ribbed mussels and periwinkle snail.

(soft music) So here's a horseshoe crab that we found in the bay.

And you can see all that algae, the seaweed.

It's healthy algae and it's growing on the back of the horseshoe crab.

And a horseshoe crab, you have to be very careful when you handle one, you have to pick it up not by its tail, but by its sides.

So here Dr.

Williams is is flipping it over and showing the different parts.

And you can see that in addition to the seaweed growing on it, there's a whole bunch of snails that are catching a ride.

They become part of the habitat that this horseshoe crab is creating.

And the shell is there and they will travel around with it.

And it's very, very cool.

And this is a very healthy horseshoe crab.

And you can see that the claws are not really meant for hurting or pinching, it's more for grabbing food, and for latching on during the mating process to the other shell.

So these are all coming in to reproduce and create more horseshoe crabs.

And they come into the shallow warmer waters of the bay.

And we're so lucky to have found an example of a horseshoe crab right there when we were seining.

So here's a great example.

These creatures are over 450 million years old, not this specific grab, but their animal type has been around for over 450 million years.

It's related more to the spider than to the actual crab.

But you can see how all that algae is growing there on it.

So it's becoming quite a part of the ecosystem.

And that tail is flipping around like that.

They use their tails to flip themselves back over and right themselves if they ever become flipped over.

So that's why the tails are so important.

They're not a weapon.

It's to help them get back over almost like if a turtle were to get stuck on its back It could use a tail like that.

- [Kyle] As everyone Sees that it goes back to being happy and safe.

And have a little bit of an adventure, meeting a bunch of scientists across the state young scientists and learners.

Now you said that the female doesn't pose a grave risk of hurting you but with a male's close be more likely to cause any?

- [Dunlea] They can.

- Can we tell this is a male or a female?

- [Dunlea] No, hard to tell but females can be larger.

- [Dunlea] Now what's interesting is having a look at their eyes though.

'Cause you crabs have sets of eyes.

- [Danlea] Really!

(mumbles) (chuckles) (mumbles) - Horseshoe crabs have numerous set of eyes.

They have varies sensory things.

There's a main set of eyes You can see here they're really obvious.

There's also some up front.

They all see different wavelengths, different types of light.

That's how they navigate through the water.

This one again, has lots of stuff growing on it.

But we'll let her get back to crawling around, - [Dunlea] I think we're just coming out of a new moon.

Horseshoe crabs wait for the new moon to breed and come on shore to lay their eggs.

Gives them some cover from predators in the darkness.

So these might be a little bit behind, but generally this time of year is when they're gonna be working.

- [Kyle] He's looking for a place to hang out.

- [Amy] You are saying the females are bigger, and the that definitely looks like the size of two that we saw before.

We're just coming out of the new moon incidence the time they like to breed and come out to lay their eggs (mumbles) - [Dunlea] Another very important part of the food chain when it comes to the migratory birds all right?

- [Kyle] Yeah, So the eggs that they lay are key to birds that are traveling this time of year.

- [Dunlea] I love the word horseshoe because it's an example of a special kind of word.

What's special about the word horseshoe?

I see a lot of hands going up.

Go ahead and say it.

What makes the word horseshoe different from other kinds of words?

If you said it was a compound word, you're absolutely right.

What is a compound word?

A compound word is two words that come together to make a new one.

And you've got the words horse and shoe.

So we could split the word right there in the middle, and you'd have two words that still exist.

Horse and shoe.

Horseshoe is one word, and then crab.

A horseshoe crab is a large marine arthropod with a domed shell, long tail, and 10 legs.

I love this definition because it's got all sorts of adjectives and nouns.

The adjective domed describes the noun shell.

The adjective long describes the word tail.

And the adjective 10 describes legs.

How many?

(upbeat music) - [narrator] The horseshoe crab.

It looks more like a walking helmet than a crab, which isn't surprising since it's not a crab at all.

It's more closely related to spiders than to crabs.

This animal has been crawling around on the sea floor for a long time.

(gentle music) In fact, the earliest known horseshoe crab fossils date back 450 million years.

There are four species of horseshoe crabs around the world.

But this one, the Atlantic horseshoe crab is found along the east coast of the USA, as far south as the Gulf of Mexico.

(gentle music) The horseshoe crab lives a quiet life cruising along Sandy and rubbery sea floors, digging for worms and mollusks, like clams and scallops.

If they hang out in shallow water, there's enough light to grow a beard of green algae.

Sometimes they even become a moving substrate for barnacles, mussels and other clingy critters.

Many people think that the long tail called a telson is some kind of a stinger, but actually it has a much more practical use.

(gentle music) During the summer when the water warms up, the mating season begins.

Males hang on to the females and follow them everywhere until they're ready to mate.

(gentle music) - [Kyle] Oh, wait a minute, that one's tagged.

Did you guys read the tag off of this?

- [Male voice] Oh yeah, we're gonna-- - [Dunlea] Check these guys for tags as you go.

So this is the US Fish and Wildlife tag, we put it on.

We do it.

It's a great activity with school groups.

It's a great way to involve school groups in the research that we do.

So this is a mark recapture project where you put a uniquely numbered tag on the crab, and hope to find it again.

So it gives you information on site fidelity, do they come back to the same spawning site year after year?

How much do they move around?

How long are they around that kind of thing.

And so this is a nice find 'cause we don't do a ton of tagging at this site.

We do it sort of opportunistically.

So this is a male.

And you can tell because they have their front legs have these clutching gloves looking things called pedipalps and that's for holding on to the female.

The males also have a really concave front of the shell for riding along the females back.

And then their mouth is here at the base of the legs.

They have the book gills these flaps under their gills, And they haven't changed very much in 480 million years.

So I guess it works for them.

We always tell people don't hold them by the telson.

I'm sure there's kids out there like like me when I was growing up in beaches in plymouth and thought it was a stinger.

It's a Stinger Watch out.

But it's totally harmless.

- Pick by the tail.

- Don't pick them up by the tail.

It's to help them 'cause it can break off sometimes.

And it's critical for helping them flip themselves over if they end up on their back.

- [Female] And they have the eyes?

- They have all kinds of eyes, they have more than just these two.

They have light receptors even on the telson and-- - and underneath - other places.

- There's one right there.

- Look at this!

- Look at that.

- I'll get that.

(laughing) - I wonder-- - Oh my God that's amazing.

check to make sure they have the tags that they had last time.

- All right, you let me know when you're ready.

It does look newer.

353 399 - This is what we came for right here.

This is happening right now.

Check it out.

You can see the scraping lump in the water.

In the front is a female.

She's dug into the sand and she's laying eggs right now.

The male who's attached to her back.

He is waiting for those eggs to go in the sand and he can fertilize.

She'll get up and she'll move along and she'll dig back down.

And I mean, this is what we came out here for see this and this is what surveyors and Mass Audubon is looking for.

It's this little action right here.

That's what it's all about.

- [Dunlea] Horseshoe crabs are so interesting.

And part of the reason is just because they're so old.

450 million years is a really long time for these creatures to still be in existence.

And to find them just out in the bay is pretty cool.

So we were very lucky to find so many.

And this video really helps show what it looks like under the water and how they use their tails.

Now we're going to go and visit Viking village.

- So behind me is viking village one of the handful of working fishing ports in New Jersey.

Started in the 1920s.

Viking village has been around since then.

They are home to a lot of boats that call it their home port Majority of the industry here is gonna be scallop fishing.

- [Dunlea] Viking village was founded in the 1920s by first generation Scandinavian fishermen.

The facility was known as the independent Fish Company until it was renamed Viking village after the original Norwegian founders.

Today we are the home port to more than 40 independently-owned fishing vessels.

That's another word for ships.

Each year, about 5 million pounds of seafood is packed out here and shipped both locally and around the world.

We also ship to selected distributors, supermarket chains, retail fish markets and individual restaurants.

So they send seafood all over the world, right here from New Jersey.

We're gonna go ahead and watch a little clip about how they catch scallops.

(upbeat music) - We're gonna be fishing is 35 miles off Cape May, 60 miles from Bernaget light.

It's formerly known as a flex area now it's all one big area.

A day boat scallop is a trip that's done in a 24 hour period.

So then, you go out, It's cut quick, it's fresh, it's back to the dock quickly get sent to the restaurant quickly.

Day boat scallop the boat's out and back as fast as it can.

It's caught on the ocean it's never actually packed in the fish haul and ice.

Bagged up, it's in the dock and on the truck and on it's way out in the morning.

They're kind of expedited out in the dock in the last bunch of years since I started all these rotational closed areas have allowed the scallops to grow not be beat up and the population really exploded the flex area as a spot where the amount scallop per yard was like a number I never thought possible So, it's really work.

It's a lot of cooperative research with fishermen, fishing service, environmentalist So it's a real success.

(upbeat music) - [Dunlea] I think the scallops look like pumpkin seeds.

That is an example of a simile when you say something looks like something.

(upbeat music) - So we know they landed a lot of scalps.

So what happens after the dredge brings them on board?

So I'm standing here with Kenny Klein, one of the major... Ken I wanna know how much did we catch today?

- 600 pounds.

- 600 pounds, that's the quota, right?

- That's the quota for a day trip.

- Okay, now once they're landed, what are the next steps to ensure a table quality scallop?

- They're gonna be iced up until we get to about three miles off the beach.

And then we're gonna pack them up keep them on ice until we get to the dock.

We're going to offload them, put them on scale, and put them right back into ice.

- What size are you targeting today?

- 10/20s and U-10s - [Dunlea] We walked around the facilities and checked out where they package and weigh.

And prepare the seafood that's been fresh caught to be shipped locally, statewide, across the country and even worldwide.

And you can see lots of weights and scales.

Different people doing their jobs.

- Are going out today?

- [Woman] No, and how far do you have to go for that?

- Yesterday I was about 40 miles due East, Just 48 hours 70 miles South East of cape Mady which is just a quarter mile up the kendy line longs berry is about 200 miles - [Woman] Wow.

- I'm going over bottom Saturday.

I'm going out for a week (mumbles) - [Woman] And how many scallops can you bring back?

- Trip down I'm going to tender 12,000 of them.

(mumbles) - [Dunlea] Wow!

- With the virus no you can't taking the(mumbles) - [Dunlea] So you're getting the boat all ready to go out today?

- Yes, not really Saturday but... - [Dunlea] Saturday.

And these extend out they just dropped down and... - [Man] Yeah, these spring out.

- [Dunlea] The booms.

(mumbles) - [Dunlea] Thank you very much, safe travel.

- [Amy] Oh they look so yummy.

- [Dunlea] Those scallops right?

Wow, those are fresh scallops.

So the fishermen will take the scallop and they'll shock it.

And that's what you call when you're opening a shell and taking out the contents.

And there's gills in scallop and it has eyes.

And what you do is you take the whole shell, usually as its whole like that you take the knife and you shock it with a shocking knife.

And you scoop out all the other parts that you don't want.

That when you take it all out, you're left with just the scallop.

And that's what you get when you buy boo.

(machines roaring) (Beeping) (mumbles) We have the scale.

Now we're gonna go visit Barnegat lighthouse.

Beautiful Barnegat lighthouse is located at the northern tip of the island of Long Beach Island.

Barnegat, lighthouse or Barnegat light, colloquially known as old Barney is a historic lighthouse located in Barnegat lighthouse State Park on the northern tip of Long Beach Island, in the borough of Barnegat light.

It's in Ocean County, New Jersey.

It was first lit in 1857, the current tower.

There was an existing lighthouse in 1835.

But they had to rebuild it.

The current tower height is 169 feet.

In third grade, I know you were learning all year long in math about rounding.

So what would you say 169 is really close to?

What zero ending number, is 169 closest to?

That's right, 170.

So it's almost 170 feet and the 52 m. Does anyone know what that stands for?

So if you said meters Good job, 52 meters.

I told you math was everywhere.

(gentle music) All right, students and scientists It's time for an exercise break.

So please Get up time to pretend that you're gonna go for a walk on the nature trail at the Barnegat lighthouse.

So if you're able to stand up and start moving those legs, otherwise start swinging those arms.

You're going to pretend that you're walking the trail.

(gentle music) Alright scientists, it's that time again, add some more words to your list, scallop, Viking village, and lighthouse.

We're adding three more words or terms to our list and you can choose to draw pictures for them later.

I'll give you a few moments to write them out.

(gentle music) Barnegat lighthouse was built in 1857 to 1858 by the Federal Lighthouse Board.

Was first lighted on January 1, 1859.

It was relit January 1, 2009, by the Friends of Barnegat lighthouse State Park.

The present lighthouse replaced an earlier lighthouse built in 1835.

The plane of the light is 172 feet above sea level.

Barnegat lighthouse was built as a first order light and was originally equipped with a Fresnel lens.

The original light was extinguished in 1927.

A new modern Fresnel lens was purchased by the Friends of Barnegat lighthouse State Park and lit on January 1, 2009, exactly 150 years after the first light was lit.

A new lens can maintains the original flash pattern and is visible up to 22 nautical miles.

(gentle music) - Here We have another crustacean.

This is called a spider crab.

And this one is no longer alive.

It's the exoskeleton that is left and probably hopefully was a good meal for some seagull or some other shore bird here.

And we have these nice long legs.

These ones are kinda crazy looking.

They're really tall.

They kind of wobble around on their legs underneath the water actually you can see another one right here.

- [Dunlea] Oh wow!

- Looks like nice piece of art.

- [Dunlea] That's almost like an archaeological dig.

- I know right?

I need my little cue fresh out.

That has these big long legs they can go this way.

And so you can see some of the claws.

They're pointed.

These are for more walking, whereas these are more for catching prey and defense.

And so they walk along.

And they're not really aggressive.

But anything.

If you go into their home like the ocean, they might protect themselves and try to nip at your feet.

But they're not aggressive.

They're more scared of you than you'd be scared of them.

They'll probably just run away and try to camouflage.

- [Dunlea] So are these more found at the ocean than the bay or do they kinda go to both?

- They go to both, I've actually saw some little shells.

They weren't this big in the bay.

Usually when you see things in the bay, they're younger, they're kinda in a more protective area.

Just like we have nurseries for human babies.

We call the bay a nursery area for a sea life.

And so that's kind of more protected, less predators, and so they find a lot more places to kinda hide out.

And I have another cool thing over here, which I see.

I wonder if anyone knows off the top of their head what this is.

- [Dunlea] Oh, I know some students out there are raising their hands out there go ahead and call out your answers - Just say it out loud.

So we call these common name called a mermaid's purse.

Which is because it looks like it could be a nice little purse and a mermaid might carry to a party but actually it is another type of animal that is real and lives in our ocean.

So it is a skates egg case or rays egg case.

And so inside you can kind of see it's cracked here so there's probably nothing inside of it right now.

But the baby Ray's grow up in here.

And then they come out holes in the side and they go off and they live in the ocean.

- [Dunlea] And then flap their wings when they come out?

- Yeah unflap their wings.

I've watched really,really cool videos never got to see it in person, but you can look it up.

Look videos up and you can see them come out and they just look so elegant, so beautiful.

(gentle music) But We see a lot of left on the beach.

And they're kind of a really cool thing to show us how our beaches are connected to our deeper oceans.

Even in animal that doesn't normally come on to our beaches still has a product that comes from them.

They end up on our beaches, breaks down and provide nutrients to our ground.

- [Dunlea] Okay scientists add Rugosa rose, spider crab and mermaid's purse to your lists.

And don't forget to have that apostrophe S on Mermaid, because that shows possession.

Rugosa Rose, spider crab and mermaid's purse.

I'll give you some time to write that down.

(gentle music) Some of the other animals that we can find off our coast of New Jersey are humpback whales.

We often see them in the fall and in the spring.

When they jump out of the water like this, and splash back in, it's called breaching.

It's an amazing sight to see.

And sometimes they even swim quite close to the beach.

If they are it's always because they're chasing food, schools of fish.

Another animal that you'll see off the coast a lot in New Jersey is the Atlantic bottlenose dolphin.

Here is a whole group of them.

And when you have a bunch of dolphins, they're called a pod.

And so here is a super pod.

They counted over 100 dolphin in this part of the jersey coast.

It's an amazing thing to see.

(gentle music) Another common sighting would be for the seal.

Now seals like to play in the water and they get tired.

So they come up and they take a rest on the beach before they go back into the water.

If you ever see a seal on the beach, you should never walk up to it.

Always give it a lot of room because you might scare it back into the water and it might not be ready to go back in the water yet.

This seal was on Long Beach Island in May in Ship Bottom.

Okay, scientists, I promise this is the last of the list.

whales, dolphins, and seals.

And that completes our list for today.

And you can go back and draw any of them that you wish to draw.

Or color and create an entire drawing or a picture based on all the words you learn today.

(gentle music) So scientists, I hope you enjoyed your wonderful trip to Barnegat Bay.

I hope you enjoyed exploring like we did and discovering them wonderful and amazing array of wildlife and water life.

And I hope that you have enjoyed all the various places that we visited today.

- Thank you so much for coming along on this journey with me.

I'm always so excited that no matter how many times I go out in my environment that I always see something new.

No matter where you are, you can be a scientist, whether it's looking out your window, or just at an area that you see every single day while you're on a walk.

You get to be able to see new things that live in that area and interconnected in so many different ways.

- So go out and discover the biodiversity that's all around you wherever you are in this wonderful state.

Because no matter where you are, there are birds, there are animals, there's insects, there's so many amazing things with waiting to be discovered by you, because you are a scientist and you're ready to go out and explore your world the way we explored ours down here.

So thanks for joining us and stay safe.

Keep on learning.
