Limulus polyphemus (lat.- Xiphosura) The Xiphosura are an order of marine chelicerates that includes a large number of extinct lineages and only four extant species in the family Limulidae, which include the horseshoe crabs. The group has hardly changed in millions of years; the modern horseshoe crabs look almost identical to prehistoric genera such as the Jurassic Mesolimulus, and are considered to be living fossils. The most notable difference between ancient and modern forms is that the abdominal segments in present species are fused into a single unit in adults.
