Eastern Indian Ocean: endemic to southern Australia.
東印度洋: 澳洲南部的特有種。

Length at first maturity / 大小 / 重量 / 年齡

Maturity: Lm ?, range 20 - ? cm
Max length : 35.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 9002)

生物學特性     字彙 (例如 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.

通常用海藻出現沙子區塊鄰近礁石之上, 吃糠蝦與其他的甲殼動物。 卵胎生的.(參考文獻 205) 雄魚帶卵在一個孵卵袋是在尾部下面發現.(參考文獻 205) 最引人注目的例子之一偽裝: 沒有一個獵物及掠食者認得它作為一個魚。

About 250 eggs are incubated by males on the underside of the tail, where they are embedded in spongy tissue (Ref. 31838).東印度洋: 澳洲南部的特有種。

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 (0.00177 - 0.01127), b=3.00 (2.78 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (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.
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (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);
