Fish evolution
The supportive elements of the fins (basal or radial bones or both) have changed greatly during fish evolution. Some of these changes are described in the section below (Evolution and paleontology). Most fishes possess a single dorsal fin on the midline of the back. Many have two and a few have three dorsal fins.

In 2018, fisheries around the world pulled in 178 million tons of fish, nearly five times the amount caught in 1960. The rise in large-scale fishing involved massive overfishing, which drastically reduced the population of dozens of species.These were the ancestors of modern sharks and rays. Lobe-finned fish, also known as anglers, would evolve into the first tetrapods, four-legged animals, and eventually crawl out of the water onto dry land around 450 to 350 million years ago. This makes lobe-finned fish the ancestors of all land vertebrates today.Although a great many fossil fishes have been found and described, they represent a tiny portion of the long and complex evolution of fishes, and knowledge of fish evolution remains relatively fragmentary.

Few fish live more than 10 years old, but some can live up to 15–20 years.Abstract Evolution of schooling behavior in fish is discussed. For the first time, schooling was formed in early Teleostei ca 200-220 Ma years BP. 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 ...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 ... The scientific definition of fish is complex and can be a little confusing. Here is a much simplified definition. Fish are: Chordates, they have a backbone or notochord (cartilaginous support). Live almost entirely in water.

Fishes invaded and ruled the oceans and fresh waterways during 500 million years of evolution, finally emerging onto land, albeit briefly. Major clades thrived and then died out or were supplanted by other groupings with supposedly greater advances. The transition from hagfish to finned fish is a lengthy and complicated process.
