Horseshoe crabs are amazing to see along the beaches from Maine to Florida. We often see them in the touch tanks at public aquariums. They are cool looking with their armored shell and prehistoric look. In fact, they are prehistoric. They have been around for 450 million years with little change in their looks.  Humans have found an important use for them as well and that alone fuels the need to protect these prehistoric species.  Listen to the episode to find out why.  Do you know why horseshoe crabs are not really considered crabs?
