00:00We have a ton of incredible species here at the South Carolina Aquarium, but probably the most unique is the horseshoe crab. Here are five cool facts about them.
00:11Number one, horseshoe crabs have blue blood, and that blood contains special cells that can help fight infections, not only for the horseshoe crab, but for humans as well.
00:21Number two, horseshoe crabs are experts when it comes to sight. They have 10 eyes located all around their body, and some of those eyes act as light sensors.
00:30Number three, when horseshoe crab babies are hatched, they are the size of your fingernail, and they will continue to grow up to the size of a dinner plate.
00:39Number four, horseshoe crabs are not actually crabs. What? In fact, they aren't even crustaceans.
00:47They lack antennae, and they are more closely related to scorpions than spiders.
00:52Number five, if they lose a limb at a young age, they can grow it back after they molt.
00:57Horseshoe crabs can molt up to one to two times per year.
