  Traditionally, a class of vertebrates that breathe with gills rather than lungs, live in water, and generally lay eggs, although some bear their young alive. Some biologists consider the fishes a “superclass,” and divide them into three classes: bony fishes, such as sunfish and cod; fishes with a skeleton formed of cartilage rather than bone, such as sharks; and fishes that lack jaws, such as lampreys.
