    Arguably the shark is not a fish, if by fish you mean Osteichthyes 🐟

    Although personally I’m both “a fish is the thing I think of as a fish” and also “we’re all fish”

        You don’t know me! I could be a cartilaginous fish for all you know. (I have to use voice to text because I don’t have lobed fins)

      they are cartilaginous fish, in the elasmobranchii subclass, the other related group is the holocepheli(the chimaeras, ratifishes) and also the extinct “sharks” in the carbineferous were all related to chimaera instead of sharks.
