Migration of the eye

The bottom of the sea is inhabited by flat and very special fish, pleuronectiformes. They're the reboil, the sole, the rooster and their family. They are asymmetric fish with a very special migration in development: the larvae are born with the “typical” appearance of the fish, but then the eye of one side migrates to the other.
