    Yeah, I’m not really arguing for or against the word fish technically fitting all land animals. I think that using it that way showcases the problem of trying to fit common terminology like “fish” into the scientific taxonomic system. The definition of fish has no use in that context.

    Also, there are fish which are also arguably tetrapods https://en.m.wikipedia.org/wiki/Sarcopterygii

      That’s fair. Honestly, all of taxonomy is just lines we draw, and all of evolution is really a fuzzy gradient. We can’t even figure out where the line for ‘human’ begins, because that’s also a meaningless term, really.

      So the fact that we’re fish is as meaningful (or meaningless) as the fact that we’re human.

      (And thanks for the link! That’s a cool, uh, ‘fish’.)

        Yeah, this is the distinction I’m trying to draw between “common” and “scientific” terminology. Scientific taxonomy is based on evolutionary history, rather than just superficial traits like “has gills, fins, and lives mostly in water.”
