The hogchoker has a flat, rounded body that is dark brownish-gray on top and pale on the bottom. Adults have:

Small eyes that are both located on the right, or top, side of the head.

A rounded head with a small mouth.
Narrow, black vertical lines or rounded spots on the top side of the body.
Dorsal and anal fins that stretch around the body from the head to the tail.
