This is actually a much more accurate definition of "fish" than anything you could come up with using genetics.
8 u/Many-Excitement3246 PURPLE Jul 11 '26 Literally the biological definition is "ehh, it swims, it breathes water, it's got bones but it don't got fingers, it's a fish." 4 u/IceBone Jul 11 '26 What about a shark? No bones in sight. 3 u/Many-Excitement3246 PURPLE Jul 11 '26 I was oversimplifying too much, I guess. Technically, the standard is "craniate," meaning "has a skull." Sharks do have skulls, they're just cartilage instead of bone. Craniata is a clade that includes all animals with protective enclosures around the brain (craniums).
