Scaleless Goby, Schismatogobius hoesei (Keith, Lord & Larson 2017)

More Info


Distribution

Endemic to the wet tropics region of Queensland, and recorded from the Endeavour River to Liverpool Creek.

The Scalesless Goby inhabits freshwater creeks and rivers within 50km of the sea. The species prefers sandy and fine gravel substrates with slow to moderate but steadily flowing relatively clear water - usually in shallow transitional areas between pools and rapids.

Features

Dorsal fin VI + 1-9; Anal fin I, 9; Pectoral fin 15-17; Pelvic fin I, 5; CAudal fin 11-12 (branched rays).

Size

To around 4cm SL.

Colour

Yellow with 3 broad, brown bars crossing back and diagonally forward down sides to belly; first under first dorsal, second under second dorsal, and third just behind second dorsal; sprinkling of minute brown specks between bands, leaving ground color as a series of white spots and dots; wide, brown blotch or crossband in front of first dorsal, above base of pectoral; brown or black reticulations on lower half of body behind pectoral; cheeks and region behind eyes more or less dotted with small, dark brown spots. First dorsal fin with two brown to black stripes or 2-3 rows of deep brown spots; second dorsal with 4 rows of dark brown spots appearing as cross-bars; base of caudal with white spot surrounded by broad, dark brown band, followed by 2 large white spots near upper and lower margins; rest of fin with large brown spots forms cross bars; pectoral crossed by 3-4 rows of large brown spots; pelvic and anal fins colorless.

Feeding

Feeds on small insect larvae.

Biology

Oviparous, benthic spawners. Males construct a nest in coarse substrate into which the female deposits eggs. Eggs are adhesive. Larvae are likely to hatch within around 4 days.

Etymology

The species is "named hoesei in dedication to Doug Hoese, eminent gobyologist and good friend who first collected this species in Australia and recognised its significance".
