From the fifty-one-foot whale shark Rhincodon typus to a less-than-one-half-inch fish in the minnow family--the tiny Paedocypris progenetica--fish certainly carry a lot of weight . . . or do they?A fish's heft in water may vary, but these diverse aquatic animals certainly carry a lot of weight in our ecosystems and environment. From freshwater to ocean habitats, Judith S. Weis offers a fascinating look at these deceptively simple creatures. Fishes may appear to live a dull existence, but appearances change once we understand more about how they survive.

A captivating read for fish enthusiasts of all ages--naturalists, environmentalists, aquarists, scuba divers, and students--this is also the perfect primer for those just about to get their feet wet.
