Horseshoecrabs resemble crustaceans, but belong to a separate subphylum, Chelicerata, and are closely related to eurypterids and arachnids. The earliest horseshoecrab fossils are found in strata from the late Ordovician period, roughly 450Mya.
Horseshoe crabs aremarine arthropods of the family Limulidae and order Xiphosura or Xiphosurida, that live primarily in and around shallow ocean waters on soft sandy or muddybottoms. They occasionally come onto shore to mate. They are commonly used asbait and in fertilizer. In recent years, a decline in the population hasoccurred as a consequence of coastal habitat destruction in Japan andoverharvesting along the east coast of North America. Tetrodotoxin may bepresent in the roe of species inhabiting the waters of Thailand. Becauseof their origin 450 million years ago (Mya), horseshoe crabs are consideredliving fossils.
