Do all flounder face the same way?
Flounder are specially adapted to a life on the bottom. So much so that one eye “migrates” across their head as they get older, until both eyes are on the same side of their face. Fluke are “left-facing,” meaning that when you hold one up, their head will be in your left hand when their eyes are above their mouth.
