All Horseshoe Crab and Decapod Families

Horseshoe Crab and Decapod Families is a Browse By group of the Nature Atlas that gathers families of two arthropod lineages that live in the sea or along its shores, the horseshoe crabs, which are chelicerates more closely related to spiders than to crabs, and the decapod crustaceans, such as the hermit crabs. An entry belongs here when its own cited article describes a family of horseshoe crabs or of decapods, as it does for Limulidae, the living horseshoe crabs, and Coenobitidae, the land hermit crabs. It excludes the spider, coral and cephalopod families, which have groups of their own. The group lets a reader compare two very different shore-living arthropod lineages.
