    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.
