Class Actinopterygii: The Ray-finned Fishes


We are all amiliar with fish as they are a key food source for humans as well as many other animal species, including birds, reptiles and mammals. Fish are vertebrate animals with a boney structure and central nervous system, and have gills so they can gather in oxygen from the water to help them breath in an aquatic environment. With fins instead of limbs, these help fish move efficently through saltwater or freshwater habitats.
