More on author: Castelnau . Environment: milieu / climate zone / depth range / distribution range Ecology Freshwater; benthopelagic. Subtropical; 18°C - 24°C (Ref. 12468 ); 30°S - 34°S Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri Africa: endemic to South Africa, occurs in Cape coastal streams and rivers from the Krom and upper Gamtoos River systems (south coast) to the Clanwilliam Olifants system (west coast)(Ref. 32965 , 52193 , 93589 , 93786 ). Length at first maturity / Size / Weight / Age Maturity: L m 3.9 , range 4 - 4 cm Max length : 7.5 cm TL male/unsexed; (Ref. 52193 ) Short description Morphology | Morphometrics Dorsal spines (total): 0; Dorsal soft rays (total): 9-13; Anal spines : 0; Anal soft rays : 9 - 14; Vertebrae : 36 - 42. Diagnosis: body slender and cylindrical, without scales; dorsal fin placed far back over anal fin; caudal fin truncated; mouth terminal, jaws with teeth; large eyes; internal organs visible in live specimens (Ref. 52193 ). Loss of two laterosensory pores beneath the lower jaw; elongate caudal peduncle (Ref. 93822 ). Biology     Glossary (e.g. epibenthic) Facultative air-breathing in the genus (Ref. 126274 ); May penetrate some distance inland and is widespread in lakes and rivers (Ref. 3563 ), which may be either acid (pH 5-6,5) or alkaline (pH 8-9) (Ref. 93592 , 93822 ). Prefers gentle currents within shelter of banks near the head of pools (Ref. 3563 , 52193 ). Small but extremely hardy, they are known to tolerate a wide range of water and temperature conditions (Ref. 5214 , 6164 , 52193 , 93591 , 93592 ). Feeds on small drifting invertebrates (Ref. 7248 , 52193 ). Spawning period occurs in spring up to middle of summer (Ref. 5214 , 33843 , 52193 ), depending on the conditions (Ref. 52193 ). Ripe eggs are demersal, relatively large and numbering about 30-40 (Ref. 93592 ). Their small size and cryptic color enable them to avoid predators (Ref. 52193 ). Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae Breeding occurs in spring or summer depending on local conditions (Ref. 52193 ). Galaxias zebratus does not migrate to the sea for breeding purposes (Ref. 41543 , 93592 ).

Bayesian length-weight: a=0.00490 (0.00205 - 0.01170), 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 (Ref. 69278 ):  3.5   ±0.37 se; based on food items. Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (Fec<50). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100).
