Elasmobranchii (sharks and rays) > Myliobatiformes
(Stingrays) > Gymnuridae
Etymology: Gymnura: Greek, gymnos = naked + Greek, oura = tail (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; depth range 28 - 37 m (Ref. 9918). Tropical
Length at first maturity / Size / Weight / Age
Maturity: Lm 47.6, range 47 - ? cm
Max length : 106 cm WD male/unsexed; (Ref. 58048); common length : 20.0 cm WD male/unsexed; (Ref. 27550)
Eastern Indian Ocean and Western Central Pacific: India to Indonesia, including Singapore and Thailand.
Demersal inshore, in shallow depths to at least 37 m (Ref.58048). Also found offshore (Ref. 9918). Ovoviviparous (Ref. 50449). Smallest individual was 27 cm WD. Caught often by demersal trawl, trammel and gillnet fisheries, and occasionally using tangle nets. Utilized for its meat, but of limited value due to its typically small size (Ref.58048).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00488 - 0.04699), b=3.03 (2.78 - 3.28), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.9 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (47 of 100) .
