Ray-finned Fishes

Ray-finned fishes, also known as Actinopterygii, are an important group of marine life characterized by having fins supported by bony rays. They are found in marine environments and are a diverse group of species, with over 30,000 known species. They range in size from small minnows to large tuna and swordfish and have a bony skeleton, a streamlined body shape, specialized scales, and specific features that help them survive in their marine environments. They are also important for human use, as a major food source and recreational fishing, and play an important role in marine ecosystems as both predators and prey.
