肉鳍鱼总纲
Also known as lobe-finned fishes, lobe-finned fish
硬骨鱼的两大演化支系之一
AI overview
Sarcopterygii is a group of bony fishes known as lobe-finned fishes, distinguished by muscular, lobed fins supported by skeletal structures inside them, unlike other bony fishes whose fins are supported only by bony spines. This group matters because their unique fin structure represents a fundamentally different body design among vertebrates that sets them apart from the more familiar ray-finned fishes.
