350 different types of sharks live all over the world and almost
all tropical species of sharks are found in Palau. Species most
often seen in Palau are gray reef sharks, blacktips and whitetips.
Sharks are cold-blooded fish and have a skeleton that is made
of cartilage. One indicator of the species type is the sharks'
teeth. Their teeth are species specific because each species
has adapted to a particular diet. Some sharks eat only one kind
of animal while others are not as choosy. Most sharks are nocturnal.
Seeing schools of sharks around Palau is rare, but should always
be treated with caution.
