More Info


Distribution

Known only from northeastern Australia from the Victoria River, Northern Territory, and the Gregory River to the Wenlock River, and east to the Walsh River northwest of Chillagoe, Queensland. Inhabits clear or turbid waters of freshwater streams, on sand or gravel bottoms.

Features

D 66–78; A 53–59; C 16; P 5-8; V 6; LL 84–97; Tr Sc 33/1/42.
Head and body extremely compressed (flattened); body depth 2.9 in total length (34.5%), ovate. Snout projecting well in front of mouth. Eyes on right side of body; diameter 7.2 in head length (13.8%), interorbital 6 in head length; lips, lower margins of snout and interopecle profusely papillose, lower nostril in patch of cirri above upper lip.
Scales finely ctenoid on both sides; preopercle hidden by scales; lateral-line curving downward from near dorsal margin of head to above opercular opening, then straight on lateral midline to base of tail
Dorsal fin origin on snout in front of upper eye; anal fin origin below pectoral fin base; dorsal and anal fins united with basal part of caudal fin; pectoral fins small, 2.5 in head length; ventral fins symmetrical, subequal, separated from anal fin; caudal fin pointed.

Size

Reaches about 15 cm TL, common to about 10 cm TL

Colour

Brown to tan with irregular darker brown blotching, white on ventral surface.

Feeding

An ambush predator whose flattened body and colouration provides excellent camouflage particularly on sandy substrates. Feeds on small fishes and crustaceans.

Biology

Oviparous, likely to produce small pelagic eggs. Larvae start out with eyes on either side of the head as in other fishes but as they develop one eye migrates over the top of the head to the other side and they become benthic.
