More Info


Distribution

Endemic to the Kimberley region of north Western Australia: widespread in the neighbouring Charnley, Calder and Sale rivers that drain westward off the Kimberley Plateau. Prefers slow flowing deep-water habitat over sandy to rocky substrates, often near crevices, around aquatic plants or near woody debris. 

Features

Dorsal fin VI-VII + I, 10-13; Anal fin I, 10-12; Pectoral fin 14-15; Caudal fin segmented rays 15, branched rays 11; Longitudinal scales 30-32;  Transverse scales backward 9-10; Predorsal scales 14-15; Postdorsal scale count 8-11; Gill rakers (outer face of first arch) 2-3 + 8-11.
Body slender, compressed, more so posteriorly; body depth at anal-fin origin 14.1-21.2% of SL; body depth at pelvic-fin origin 14.3–19.3% of SL Large males with somewhat convex nape, 'hump' absent; eyes not protruding above head profile.

Colour

Head and body tan to brown, slightly lighter tan-brown on ventral surface of head and abdomen, scale margins narrowly outlined with dark brown. Dorsal saddles and vertical bars alongside of body dusky to dark brown. Series of small dark blotches/bars below midline black. Internal narrow pale golden-brown stripe running from eye nearly to midcaudal fin base, following top of vertebral column. Short black vertical blotch on lower base of caudal fin. Grey-black bar on pectoral base. Head above eye brown to dark brown. Head under eye light brown to translucent. Scattered spots or blotches of iridescent gold pigment may show through body wall of upper abdomen and side of head. Lips dusky grey to light brown. Pupil surrounded by rim of pale gold, most of eye brownish-gold. Dorsal and anal fins dusky grey to transparent basally, sometimes with whitish spots, followed distally by broad bright orange submarginal band (sometimes split into two bands in first dorsal), and narrow dusky-white band at fin margin. Caudal fin with light orange to dusky in middle rays, bright orange outer rays for ¾ of ray length, the light dusky fin margin. Covered in white spots that may form 3-4 wavy, slightly convex bands.

Feeding

with a diet consisting mainly of insect larvae and microcrustaceans.

Biology

Although little is known about the ecology of this species, other members of the genus Hypseleotris are oviparous benthic spawners. Breeding was observed during the dry season, however, they likely breed several times throughout the year.

Remarks

The Ngarinyin people know this fish as Garawud jirri.

Similar Species

Differs from its congeners in having the following combination of characters: dorsal and anal fins with broad bright orange submarginal band (sometimes split into two bands in first dorsal), and narrow dusky-white band at fin margin, head with distinctively sparse pattern of sensory papilla on lateral and dorsal surface. Pectoral fin rays 14–15 (usually 15), vertebrae 26, preopercle fringed with scales, sometimes naked, postdorsal scale count 8–11, usually 9, longitudinal scale count 30–32, usually 30, and predorsal typically naked, rarely scaled, and top of eye does not extend beyond dorsal surface of head.
In previous studies, this species was treated as Hypseleotris kimberleyensis.

Etymology

The specific name garawudjirri is a combination of the words Garawud Jirri, that mean ‘light/little fish–floating around’ in the Ngarinyin language. It is pronounced: Gaarr—Arrd Jiddy. The name was provided by Ngarinyin elder Matthew Martin in consultation with the Wilinggin Aboriginal Corporation. The Wilinggin Aboriginal Corporation represents all the Ngarinyin Traditional Owners and their interests. in the Ngarinyin language of the Kimberley Region. The name refers to how the fish is often seen nearly in the water column amongst fallen leaves and Pandanus roots.
