There are no strict data on the presence of this form of social behavior in older Craniata. It is supposed that the evolutionary path of schooling followed from asociality to protoschools and then to true equipotential schools. The schooling ...The cyprinid fish (8mm) and the whale shark (12m) are some of the smallest and largest fish in the sea.

Fish - Actinopterygii, Ray-Finned, Aquatic: Class Actinopterygii (ray-finned fishes), in existence since the Early Devonian, is the largest class of fishes with about 26,900 living species. Actinopterygians comprise three evolutionary radiations: Chondrostei, holostean, and Teleostei. Ichthyologists emphasize the skeleton in classification, but studies also include head and body length, teeth ...Fish have adapted to their environment through the evolution of gills, swim bladders and fins.
