In a marine environment they change colour to much more silvery overall and have a few indistinct spots. Breeding male has enlarged jaws with tip of lower jaw forming a hook

Short-based dorsal fin high on back originating in front of ventral fins; fleshy adipose fin behind dorsal. Colour variable, usually brown or olive with dark spots on the sides, dorsal fin and gill covers. Tail with few if any spots. Body paler below mid-line, and most spots surrounded by a pale halo and often reddish.
