Etymology: Galaxias: Greek, galaxias, ou = a kind of fish (Ref. 45335)macronasus: A combination of Greek and Latin, from Greek macro (large), and the Latin nasus (nose). This combination is justified on grounds that it produces a euphonious and easily spelled name.

Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 7 - 9; Raggi anali molli: 7 - 11; Vertebre: 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).
Body shape (shape guide): elongated.

Biologia     Glossario (es. epibenthic)

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).

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00206 - 0.01165), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resilienza (Fonte Biblio. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
