Eastern Indian Ocean: endemic to southern Australia.

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 20 - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 9002)

Biology     Glossary (e.g. epibenthic)

Usually occur over sand patches close to reefs with kelp, feeding on mysids and other crustaceans. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). One of the most spectacular examples of camouflage: neither prey nor predators recognize it as a fish.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

About 250 eggs are incubated by males on the underside of the tail, where they are embedded in spongy tissue (Ref. 31838).

Estimates based on models

Preferred temperature (Ref. 123201): 16.3 - 18.5, mean 17.8 °C (based on 104 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00175 - 0.01142), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.45 se; based on food items.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (18 of 100).
Nutrients (Ref. 124155):  Calcium = 22.8 [9.5, 42.9] mg/100g; Iron = 0.23 [0.12, 0.42] mg/100g; Protein = 18.3 [17.1, 19.6] %; Omega3 = 0.269 [0.137, 0.505] g/100g; Selenium = 7.82 [3.39, 18.95] μg/100g; VitaminA = 42.6 [10.2, 182.7] μg/100g; Zinc = 0.623 [0.397, 0.991] mg/100g (wet weight);
