Spotted Flounder, Ammotretis lituratus (Richardson 1844)

More Info


Distribution

Twofold Bay, New South Wales, to off Flinders Island, South Australia, including around Tasmania. Inhabits clean sandy areas in bays and coastal waters at depths to 80 m.

Features

Dorsal fin 77-82; Anal fin 54-58; Caudal fin 14; Pectoral fin 10-11; Pelvic fin (right) 9-10, (left) 6; Lateral line ~ 78.
Body deep (46-50% SL), extremely compressed; both eyes on right side of head; head reasonably small, eyes on right side separated by a narrow space; snout extended into a hook-like process projecting downwards in front of small, oblique mouth; teeth small; a small rounded lump present on the blind side near pectoral-fin tip. 
Scales very small, rather firmly attached; mostly ctenoid on ocular side, mostly cycloid on blind side; a short, lateral-line segment present above upper eye.
Dorsal, anal and caudal fins separate; dorsal fin arising on tip of snout, without greatly elongated anterior rays. Caudal fin rounded. Right pectoral fin longer than left pectoral fin. 

Colour

A well-camouflaged beige, sandy or greyish flounder, sometimes with a number of darker spots on the head, body and/or fins, and a whitish underside.

Remarks

Presumably the most common small sized species in the genus. Found regularly on the eastern and western sides of the Bass Strait.

Etymology

The specific name lituratus is from the Latin litura (= a blur), possibly in reference to 'some minute dark specks widely dispersed' on the eyed side.
