what class of arthropods do crabs belong to
Arthropod Arthropods belong to phylum Euarthropoda.[3][81] The phylum is sometimes called Arthropoda, but strictly this term denotes a (putative - see Tactopoda) clade that also encompasses Phylum Onychophora.[1]
Crustacean Each somite, or body segment can bear a pair of appendages: on the segments of the head, these include two pairs of antennae, the mandibles and maxillae;[3] the thoracic segments bear legs, which may be specialised as pereiopods (walking legs) and maxillipeds (feeding legs).[4] The abdomen bears pleopods,[5] and ends in a telson, which bears the anus, and is often flanked by uropods to form a tail fan.[9] The number and variety of appendages in different crustaceans may be partly responsible for the group's success.[10]
