Prehistoric Peculiarity

A common sight along the scenic coast of #SouthCarolina this time of year is the helmet-shaped shell of the Horseshoe Crab. This unusual creature, whose real name is Limilus Polyphemus, is actually not a crab at all, but closely related to spiders and other arachnids. Scientists have evidence that Horseshoe crabs have existed for millions of years and benefit from having no natural enemies. The outer shell, called a prosoma, has two eyes, but the creature is mostly nocturnal, feeding and mating in shallow ocean beachfronts. It also displays a long sharp tail, or telson, that is used primarily for flipping the crab over if waves turn it upside down in sand. The unusual look is not the only thing odd about the Horseshoe crab. It’s rare copper-based blood contains elements that are extremely important in human medicine, and are commonly used to test sterility of syringes and surgical tools.  Visitors wandering area beaches such as Sullivan’s island and Isle of Palms will often see the horseshoe crabs washed up near the dunes. <img.src=”Charleston Curiosities” alt=”Horseshoe Crab”
