''Galaxias'' is a genus of small, highly successful freshwater fishes, in the Galaxiidae family. They are typically found at temperate latitudes across the Southern Hemisphere. They are frequently referred to as galaxiids. Galaxiids are scaleless and somewhat tubular, ranging from very slender to quite bulky. They are somewhat torpedo-shaped, with the dorsal and anal fins positioned close to the tail. They are generally small, with typical adult lengths ranging from between 40 mm and 150 mm TL, with some stocky species attaining around 250 mm. The largest, ''Galaxias argenteus'', has been recorded at 580 mm, although 300-400 mm is a more typical adult length. ==Species== The 46 recognized species in this genus are: * ''Galaxias aequipinnis'' Raadik, 2014 (East Gippsland galaxias) * ''Galaxias anomalus'' Stokell, 1959 (roundhead galaxias) * ''Galaxias arcanus'' Raadik, 2014 (riffle galaxias) 〔 * ''Galaxias argenteus'' Gmelin, 1789 (giant kokopu) * ''Galaxias auratus'' Johnston, 1883 (golden galaxias) * ''Galaxias brevipinnis'' Günther, 1866 (climbing galaxias) * ''Galaxias brevissimus'' Raadik, 2014 (short-tail galaxias) 〔 * ''Galaxias cobitinis'' McDowall & Waters, 2002 (lowland longjawed galaxias) * ''Galaxias depressiceps'' McDowall & Wallis, 1996 (flathead galaxias) * ''Galaxias divergens'' Stokell, 1959 (dwarf galaxias) * ''Galaxias eldoni'' McDowall, 1997 (Eldons galaxias) * ''Galaxias fasciatus'' Gray, 1842 (banded kokopu) * ''Galaxias fontanus'' Fulton, 1978 (swan galaxias) * ''Galaxias fuscus'' Mack, 1936 (barred galaxias) 〔 * ''Galaxias globiceps'' Eigenmann, 1928 * ''Galaxias gollumoides'' McDowall & Chadderton, 1999 (Gollum galaxias) 〔(Precious: Gollum (the fish) risks extinction in New Zealand )〕 * ''Galaxias gracilis'' McDowall, 1967 (dwarf inanga) * ''Galaxias gunaikurnai'' Raadik, 2014 (Shaw galaxias) 〔 * ''Galaxias johnstoni'' Scott, 1936 (Clarence galaxias) * ''Galaxias lanceolatus'' Raadik, 2014 (tapered galaxias) 〔 * ''Galaxias longifundus'' Raadik, 2014 (West Gippsland galaxias) 〔 * ''Galaxias macronasus'' McDowall & Waters, 2003 * ''Galaxias maculatus'' Jenyns, 1842 (common galaxias) * ''Galaxias mcdowalli'' Raadik, 2014 (McDowall’s galaxias) 〔 * ''Galaxias mungadhan'' Raadik, 2014 (Dargo galaxias) 〔 * ''Galaxias neocaledonicus'' Weber & de Beaufort, 1913 * ''Galaxias niger'' Andrews, 1985 (black galaxias) * ''Galaxias occidentalis'' Ogilby, 1899 (western galaxias) * ''Galaxias olidus'' Günther, 1866 (mountain galaxias) 〔 * ''Galaxias oliros'' Raadik, 2014 (obscure galaxias) 〔 * ''Galaxias ornatus'' Castelnau, 1873 (ornate galaxias) 〔 * ''Galaxias parvus'' Frankenberg, 1968 (small Pedder galaxias) * ''Galaxias paucispondylus'' Stokell, 1938 (alpine galaxias) * ''Galaxias pedderensis'' Frankenberg, 1968 (Pedder galaxias) * ''Galaxias platei'' Steindachner, 1898 * ''Galaxias postvectis'' F.
