I saw a nature documentary last night that had flounders, those fish that swim on their sides, and whose eyes have migrated so that they’re both on the same side – that is, the top, if you’re looking at the fish swiming in its environment, or the side, if you’re looking at the fish’s anatomy.
The flounder who was the star of this particular documentary had his left side to the bottom, and his right side (with eyes) to the top. Do all flounders hang to the left, so to speak, or do some go to the right? Why?
When the flounder ate, his mouth opened sideways, or what looks to be sideways, because he is on his side. (I’m rather freaked out by this so I’m not being very coherant.) In addition to the eyes, are other parts of the flounder’s body (internal or external) shifting around as a result?
