Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Western Pacific: Gulf of Thailand and the Philippines to Queensland, Australia. A similar and perhaps identical species occurs in the western Indian Ocean off Mozambique and in the Gulf of Aden and is probably sympatric with the true 'Rhynchobatus djiddensis' of the western Indian Ocean and the Red Sea. Distributional range probably wider than reported, but many nominal records of Rhynchobatus djiddensis from the western Pacific and southeastern Indian Ocean cannot be identified to species.

Biology     Glossary (e.g. epibenthic)

Inhabits inshore waters on the continental shelves (Ref. 9915). Demersal on soft bottoms and near coral reefs (Ref.58048). Feeds on bottom crustaceans and mollusks (Ref. 9915). Ovoviviparous (Ref. 50449). Caught commonly by demersal tangle net, and to a lesser extent by trawl and longline fisheries (Ref.58048). Marketed fresh; fins prized for the sharkfin trade (Ref. 9915). Female specimens may reach 300 cm in length in Thailand (Ref. 9915).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00145 - 0.00999), b=3.12 (2.89 - 3.35), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.50 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Very high vulnerability (85 of 100) .
Price category (Ref. 80766):   Medium.
