Book Description
Did you know that half of all the animals in the world that have backbones are fish? There are more kinds of fishes than there are amphibians, reptiles, birds, and mammals added together. And scientists are discovering more species of fish almost weekly. Brilliantly colored or camouflaged, as big as a whale or smaller than a little fingernail, fishes are found almost everywhere there is water. The Fish Classes explores the origins of the first fishes, with a glimpse of some of the extraordinary varieties that became extinct long ago. The book also examines the five classes of modern fishes, surveys their physical features, habitats, and ways of life, as well as some of the threats they face today. Book jacket.
