Why a Horseshoe Crab?
Why not a horseshoe crab! Horseshoe crabs are incredible sea creatures that have lived on the Earth for about 300 million years, that’s about 100 million years before the dinosaurs roamed the Earth. Lots of creatures have come and gone since that time, but the horseshoe crab has lived on, practically unchanged from its 300 million year old ancestors. Horseshoe crabs are one of the few sea creatures that we have the opportunity to meet and greet at the salty ocean water’s edge. They don’t run away when they see a person coming, and they will swim right beside you, if you let them.
Many people are concerned that horseshoe crabs have a menacing look, and some people think they might sting with their tails. But horseshoe crabs are friendly creatures that have no way to hurt a human being. They don’t have a stinger in their tail. As a matter of fact, the horseshoe crab’s tail is very fragile, and can break off or become injured easily. That‘s why when you pick a horseshoe crab up, you should always lift it from the sides of its shell, and never by its tail. Horseshoe crabs can’t bite either, because they don’t have sharp teeth. A horseshoe crab’s teeth feel like the bristles of a toothbrush, which is why the foods they eat tend to be soft and easily chewed.
The horseshoe crab has only three real means of defense. First, it has a hard shell that gives the horseshoe crab some protection, although the underside of its shell is soft enough for shore birds to peck through with their beaks. If you find a horseshoe crab lying on its back on the sand, flip it over and gently place it at the water’s edge. That way the horseshoe crab won’t fall victim to a hungry sea gull. The second way a horseshoe crab can protect itself is by swimming fairly quickly when surrounded by water. If the water falls away from the shore at low tide and the horseshoe crab finds itself stranded on the wet, tidal flat sand, it is able to crawl very slowly using its pushing feet. But the most amazing way a horseshoe crab defends itself is by digging itself under the sand until it has totally disappeared, all in just a minute or two. There it can hide, in the cool, wet sand, safe from shorebirds. Despite the horseshoe crab’s ability to disappear under the sand, they are easy to find and fascinating to watch. But horseshoe crabs aren’t just another pretty face on the beach. Their contributions to the biomedical field are invaluable to us humans, and the fact that horseshoe crabs are close to being endangered challenges each of us to learn about these extraordinary creatures. Once people have a greater understanding of the horseshoe crab, it’s hoped they will have a stronger desire to help this gentle creature survive for generations to come.

The horseshoe crab’s binomial name or scientific name is Limulus polyphemus. A binomial name is the Latin name given to an organism that includes its genus and its species. The horseshoe crab’s genus, Limulus, means odd or askew, which is thought to refer to the way the compound eyes are placed on the horseshoe crab’s body. Polyphemus, which is the species, means one-eyed giant, and refers to the simple eyes located on the front of the horseshoe crab’s shell.
