Question

Characteristics features of adult form of crustacea larva

Answer 1

Crustaceans can range in sixe from 0.1 mm all the way up to 3.8m.  Like other arthropods, crustaceans have an exoskeleton which they molt to grow. They are distinguished from other arthropods such as insects by the possession of biramous (two-parted) limbs. The body of the crustacean is composed into three general regions: the head, thorax, and the abdomen. The head and the thorax may be fused together to create the cephalothorax. Each body segment can bear a pair of appendages: on the segments of the head, these includes two pairs  of antennae, the mandibles and the maxillae; the thorax segments bear legs; the abdomen bears pleopods and ends in a telson.
