Hah. This is particularly funny to me because I once got into an argument about this once.
My high school biology teacher insisted on making the distinction between sharks (Chondrichthyes) and bony fish (Osteichthyes).
In common usage, most people call them “fish” even though sharks’ skeletons are made of cartilage.
Yeah well the person I was arguing with called them mammals, which he was clearly wrong about. In any case, I’m not a marine biologist.
Definitely not mammals, and it doesn’t take a degree in marine biology to know that.
Break it down!
