I thoroughly enjoyed this informative program! THANK U PBS! I have seen horseshoe crab shells in my 20’s on the beach at St. George Island, FL (about 50-100 mi. east of Panama City, FL) and was always a little afraid of the creatures that live in them. Now, at 50 years old, I am educated on the wondrous properties of these strange looking crabs. I’d have NEVER picked one up and thought that it wouldn’t pinch me, but the man on the show put it up to his face to show that their pincers were harmless! I pray that our Lord protects these blue blooded creatures from overly greedy fishermen and the dangers of nature, that the Red Knots continue to survive, and that scientists find a way to duplicate their blood for the benefits that their fluid provides, so that no horseshoe crabs have to perish, even if it is just 13 percent a catch..
