California Flounder

Found singly, on mud and sandy bottoms, over coastal, and deeper waters, of the continental shelf.
They feed during the day, on cephalopods and fish.
Juveniles common beyond surf line.

Flatfish, Soles and Flounders are placed in their families by location of their eyes. Their are both left eye and right eye dominant families.
Flatfish bury themselves in sand to hide from predators and use their eyes as periscopes as these can rotate 180 degrees.
During pelagic larval stage these fish are not flat but become so as they grow, their bodies flatten, and one eye migrates across the head next to the other eye.
