This is true of most clams. Brachiopods are quite different. Inasmuch as their valves are seldom similar, the plane of symmetry that divides the animal into mirror-image halves passes vertically down the middle of each valve (left drawing, "Bilateral symmetry (brachiopod)"), and is perpendicular to the line along which the valves join.Adult echinoderms exhibit pentaradial symmetry and have a calcareous endoskeleton made of ossicles (Figure 15.5.1 15.5. 1 ), although the early larval stages of all echinoderms have bilateral symmetry.

It uses these siphons for respiration and gathering food. ... having body symmetry such that the animal can ...Bivalves vs. brachiopods. Bivalves and brachiopods are both types of “sea shells.” both have shells composed of two valves, but the organisms inside the shells are quite different. Typically, the two valves of a bivalve are mirror images of each other (termed equivalved). Their valves are symmetrical along a plane through the hinge.
