    I appreciate that information. However, flounders themselves are not bilaterally symmetrical. I have caught many dozens of them and it’s pretty easy to tell that they are not.

        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.

            Yeah. I just wasn’t sure at what point things are considered to be bilateral or otherwise.

            I thought it may have been during the development process, but can’t remember.

          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.

        Oh, I know. It’s very interesting. But when people imagine a flounder, they generally don’t imagine a juvenile unless juvenile has been specified.
