Flatfish

Flatfsh

Did you know that in the lifecycle of flatfish (flounders, plaice, sole, etc) that the infants swim upright like any normal fish?  It’s only as they mature that one eye migrates to the other side of the head, and they swim with one side down. According to that esteemed source of all good things, Wikipedia:

In its life cycle, an adult flounder has two eyes situated on one side of its head, where at hatching one eye is located on each side of its brain. One eye migrates to the other side of the body as a process of metamorphosis as it grows from larval to juvenile stage. As an adult, a flounder changes its habits and camouflages itself by lying on the bottom of the ocean floor as protection against predators. As a result, the eyes are then on the side which faces up.

This worries me.  You must imagine your hands held flat, thumb up, to be baby flatfishes.  At some point your hand/fish must turn palm down.  Which of your hands will become an adult flatfish?  Are all flatfish right-handers?  Or perhaps there are a few left-handers?  Perhaps one in ten flatfish may be lefties?  In flatfish world, do the righteous flatfish pick on the lefties?  Do they insist that the lefties have made the wrong choice?  That because 90% of flatfish are right-handers it’s the only natural way to be?  Are lefties cured if they swim with their eyes down?

palms down

Which one are you?
