Environment / Climate / Range Ecology

Marine; demersal; depth range 10 - 155 m (Ref. 89707).   Tropical, preferred ?; 33°N - 8°N, 44°E - 77°E (Ref. 5222)

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

Western Indian Ocean: Gulf of Aden, Gulf of Oman, Persian Gulf, Pakistan, and west coast of India. Since it has only recently been discovered, it may be expected to have a wider distribution.

Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 16-17; Anal spines: 3; Anal soft rays: 8. Distinguished by the following characteristics: head, body and fins pale, covered with numerous small close-set dark brown spots; spots on fins and dorsal parts of head and body smaller and closer together compared to those on the sides and ventrally; rear edge of caudal fin with white line and a row of blackish brown spots; presence of dark maxillary streak; body depth contained 2.6-3.3 times in SL; body width 1.8-2.4 times in depth; head length 2.5-2.8 times in SL; slightly convex interorbital, dorsal head profile almost straight; angular preopercle, with indentation above the angle and enlarged serrae below the indentation; straight upper edge of operculum; posterior nostrils slightly larger than anterior ones; maxilla reaches to below rear half of eye; front of jaws with a pair of small fixed canines; 2 rows of teeth on midlateral part of lower jaw, inner ones twice length of outer teeth, pyloric caeca 28-34 (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Known from rocky areas adjacent to soft bottoms in depths 10-155 m (Ref. 89707). In the Hong Kong live fish markets (Ref. 27253).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00604 - 0.01735), b=3.03 (2.89 - 3.17), based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.9   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.19; tmax=41).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
Price category (Ref. 80766):   Very high.
