Length at first maturity / Size / Weight / Age
Maturity: Lm 14.0  range ? - ? cm
Max length : 22.0 cm TL male/unsexed; (Ref. 48635)
Indo-Pacific: southern India to Japan, Australia and Tahiti. International trade is monitored through a licensing system (CITES II, since 5.15.04) and a minimum size of 10 cm applies.
Inhabits gravel or sand bottoms around shallow reefs (Ref. 559); muddy estuaries and near mangroves, tolerating brackish waters (Ref. 48635). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Bayesian length-weight: a=0.00676 (0.00242 - 0.01892), b=2.93 (2.69 - 3.17), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.8 ±0.50 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (tm=0.5-1).
Vulnerability (Ref. 59153
): Low vulnerability (18 of 100) .
