More Info


Distribution

Endemic to northern Australia, from Dampier, Western Australia, to Brisbane,  Queensland. Occurs in shallow-water estuarine habitats, including tidal rivers, mangrove creeks and muddy tide-pools, at depths to one metre, with substrates of sandy mud, mud and mangrove roots, logs and leaf litter.

Features

Dorsal fin VI + I,6–8; Anal fin I,6–7; Pectoral fin 14–17; segmented caudal rays 15–16, in 9/7 pattern; lateral scales 24–27; TRB 7–9; predorsal scales 6–8; opercle with at least 2 rows of cycloid scales, rarely with a cycloid scale on cheek right behind eye; shoulder girdle smooth or with narrow bony flange; tongue short and may be greatly reduced; in males, teeth in outer row of upper jaw slightly flattened, blunt-tipped or pointed, with two curved symphyseal canines behind anterior tooth rows, while in females, outer row teeth of upper jaw small, compressed and blunt-tipped.

Etymology

The specific name is from the Latin aquilonius (= north, northerly), in reference to this Australian species’ distribution around the north coast of the country.
