Morphology | Morphometrics
Indian Ocean: Red Sea, Saudi Arabia, Djibouti, and Sri Lanka. Records from South Africa, Madagascar, Mauritius and Réunion are questionable. International trade is monitored through a licensing system (CITES II, since 5.15.04) and a minimum size of 10 cm applies.
Length type refers to height (= TL - head length). Occurs in eelgrass beds (Zostera sp.) in lagoons. Used in India for traditional medicines. Diurnal. Adults pair-bond and greet on daily basis in the laboratory (Ref. 30915). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
Adults pair-bond and greet on a daily basis in the laboratory (Ref. 35709). Male carries the eggs in a brood pouch (Ref. 205). Gestation period is about 14 days depending on temperature (Ref. 30915). Clutch size is about 30-140 (from dropped clutches) (Ref. 30915).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00417 (0.00160 - 0.01085), b=3.00 (2.78 - 3.22), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (tm=0.3-0.4).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
