The Actinopterygii is the class of ray-finned fishes, sometimes called a taxonomy.
The ray-finned fishes get their name from the fact that they have lepidotrichia or “fin rays”. Their fins are webs of skin held by bony or horny spines (“rays”). This is different from the fleshy fins of the fish in the Sarcopterygii taxonomy.
