Mammals, reptiles, arachnids, insects, etc are all as far as I am aware symmetrical in appearance. Take a human for instance, make a line from the top of our head right down the middle.

Tridacna squamosa, or the fluted giant clam, is a species of giant clam native to the Indian and Pacific oceans. It is the largest living bivalve (named for the two symmetrical shell 'valves' that are connected, or hinged, by ligaments). This endangered species lives primarily in warm shallow reefs and is ...
Here's a clam. You are probably saying to yourself that we should look at the body from the outside. Let's do that. Here is an ordinary animal seen from the ...Of all echinoderms, the Ophiuroidea may have the strongest tendency toward 5-segment radial (pentaradial) symmetry. Ophiuroids are generally scavengers or detritivores. Small organic particles are moved into the mouth by the tube feet. Ophiuroids may also prey on small crustaceans or worms. Some brittle stars, such as the six-armed members of ...

Clams and their relatives, such as mussels, scallops, and oysters, are mollusks possessing a pair of typically symmetrical shells. Most are filter feeders, collecting food with their gills. Paleozoic bivalves typically lived on the surface of the sediment ("epifaunally"), but in the Mesozoic they evolved the ability to burrow more deeply into ...
