[Note Guidelines] Photographer's Note
This guy was an albino. He was almost all white with little brown color on the edge of his fins. Taken in about 20 FSW, water temp was 60. Viz was a good 30+ for a beach dive, at a place called Bass Rock.

Kingdom:Animalia
Phylum:Chordata
Class:Actinopterygii
Order:Pleuronectiformes
Family:Paralichthyidae
Genus:Citharichthys
Species: sordidus

In many species both eyes lie on one side of the head, one or the other migrating through and around the head during development. Some species face their "left" side upward, some face their "right" side upward, and others face either side upward.

Flatfish lay eggs that hatch into larvae resembling typical, symmetrical, fish. These are initially elongated, but quickly develop into a more rounded form. The larvae typically have protective spines on the head, over the gills, and in the pelvic and pectoral fins. They also possess a swim bladder, and do not dwell on the bottom, instead dispersing from their hatching grounds as plankton.[1]

The length of the planktonic stage varies between different types of flatfish, but eventually they begin to metamorphose into the adult form. One of the eyes migrates across the top of the head and onto the other side of the body, leaving the fish blind on one side. The larva also loses its swim bladder and spines, and sinks to the bottom, laying its blind side on the underlying surface.

Hy Erika
It seems that not many here are interested in underwater photography, I don't know why, beacuse, sincerly, could offer a lot of possibilities and subjects like "ground" photography. Most probably, this species maight be first time prezented here. And it is a very good picture IMHO. I like the focus on fish eyes, characteristic for this kind of fish. Well done!
