    Isn’t it referring to during development? Like as they’re forming, they are bilateral? I haven’t taken developmental biology in many years, so I’m maybe wrong.

      They are born (or hatch too lazy to look up) and their eyes move later once they get larger.

      They’re only bilateral when they’re very young. And even then, everyone is just focusing on the eyes. The body of the fish is also not exactly bilateral. Just fillet a flounder of any age (or watch a video on it) and you’ll see.

        Sorry, I’m talking about like when the fish first starts developing. Like how the initial cells orient themselves. I just have to look up what the definition actually is.
