Historical Description

Fish are aquatic vertebrates with gills. In a narrower sense, fish are the jawed mammals that do not belong to the terrestrial vertebrates. Among the animal groups living today, these include: cartilaginous fish with the sharks, rays and sea cats that live almost exclusively in the sea. Bony fishes in the broader sense, composed of carnivorous and ray-finned fishes. Fleshy fins include the marine coelacanths and the lungfishes that live in the freshwater of the southern hemisphere. The ray-finned fishes include all other fish groups, including all European freshwater fishes.
