More Info


Distribution

Known only in northern Australia from the Adcock River, WA (125°49'E) to Cooktown, QLD (15°S), but probably also in New Guinea; benthic, inhabiting freshwater rivers, creeks and billabongs, usually in slow flowing water amongst aquatic vegetation, woody debris or undercut banks.

Features

Dorsal fin VI + I, 9; Anal fin I, 8-9; Pectoral fin 17-19; Gill rakers (lower limb) 6-7. 
Body elongate, cylindrical, anteriorly depressed, posteriorly compressed, depth 4.5-5.5 in SL. Head depressed, profile straight, 2.75-3.2 in SL. Snout slightly shorter than eye to as long as eye, tip before lower margin of eye; Eye diameter 4.5-6.0 in head length; interorbital 1-2 eye diameters. Lower jaw protruding, mouth oblique, reaching to below middle of eye; jaw teeth in several rows, upper jaw with outer row slightly enlarged; outer row in lower jaw at front and a few teeth laterally of inner row enlarged. Head pores minute; some open pores around eyes and along posterior margin of preopercle. Mucous canals radiating under eye; two canals longitudinally on cheek; anterior nostril long in tube, posterior nostril short and not tube-like; nostrils and adjacent pores surrounded by an indistinct patch of papillae.
Scales on body ctenoid, cycloid on nape, breast and belly; longitudinal series 55-60; cycloid scales on head scaled above from dorsal fin to in front of eyes, on cheek and opercle; vertical scale rows 62-69; horizontal scale rows 19-20; predorsal scale rows 40-48.
Two dorsal fins, the first dorsal fin much lower than body depth; height of second dorsal about 0.67 body depth; caudal fin rounded, slightly pointed; Pectoral fin rounded, as long as head without snout; Pelvic fins separate, slightly shorter than pectorals.

Size

Maximum size around 55 cm SL, commonly to 30 cm.

Colour

Dark brown dorsally, lighter ventrally with narrow dark stripes on sides; median fins and pelvic fins with small dark spots forming transverse bands.

Feeding

A nocturnally active carnivore feeding on fishes, crustaceans and aquatic insects.

Biology

Oviparous, benthic spawners; females deposit eggs onto a hard surface and males guard and fan eggs until hatching. Eggs are fusiform, 2-2.5 mm long and 1 mm wide. Larvae hatch after 3-7 days, depending on temperature, and begin feeding within days of hatching.

Remarks

Nocturnally active.
