This quiz, titled 'Biology 1402 Exam 2 (Part 3)', focuses on the characteristics and biological processes of echinoderms, such as sea stars. It assesses knowledge on their respiration, waste removal, reproductive modes, and water vascular system. This quiz is designed for learners interested in marine biology and echinoderm taxonomy.

Brachiopods are often misidentified as bivalves.
Brachiopods were much more diverse in the past.
As in bivalves, the valves in brachiopods are lateral (left and right) to the body axis.
Most brachiopods are sessile (attached).
The lophophore resides within the brachiopod's shells.
