Living Fossil The earliest horseshoe crabs were found 450 million years ago as fossils in strata. Many think of them as crabs and crustaceans when in fact they are more related to spiders and scorpions. Under their enormous shell, their bodies also look more like those of spiders.

Horseshoe Crabs are jawless, have 5 pairs of legs and 9 eyes. Not bizarre enough? Horseshoe Crabs have blue blood – copper, not iron, is used in their version of hemoglobin: hemocyanin.
