What are the 3 types of fish?
Cartilaginous Fish, their body frame in mainly cartilage. Tough and flexible, cartilage provides enough l support to allow these fish to grow to very big sizes. Cartilaginous fish include sharks, rays, skates and chimaeras. Ray-finned fish are the most diverse of the three groups of fish. The group includes mor than 23,000 species such as salmon, trout, lanternfish, cavefish, cods, anglerfish and many others. These fish consist of bone. Lobe-finned fish are a group of bony fish that have paired fins. Ancient lobe-finned fish are thought to be the ancestors of the first four-legged land vertebrates or tetrapods.
