duri punggung lunak (Keseluruhan (total)) : 7 - 9; Sirip dubur lunak: 7 - 11; vertebrata, bertulang belakang: 47 - 51. Distinguished from all other congeners in New Zealand in having only 4-6 pelvic fin rays and only 11-14 principal caudal rays (Galaxias pullus has 14 principal caudal rays, but has 7 pelvic fin rays, and is much more stoutly built; Galaxias cobitinis has only 5 pelvic fin rays, usually has 15 principal caudal fin rays, and has a distinctly protruding lower jaw). This species has distinctly rounded snout when viewed from both dorsal and lateral perspective (Ref. 75601).
Facultative air-breathing in the genus (Ref. 126274); Collected mainly from small gravelly riffles in small streams. This fish appears to be cryptic (Ref. 75601).
