Question

Quizplus · Accepted Answer

The tail fan of many malacostracans is composed of two structures called uropods and telson. It is not the rostrum (a structure on the head), postcarapace (a section of the exoskeleton covering the cephalothorax), or endopod (part of a limb). While the last biramous appendages contribute to the tail fan, it specifically refers to the uropods and telson.
