Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 18 - 21; Anal spines: 3; Anal soft rays: 9 - 12. Distinguished by the following characteristics: dark brown or violet-black body color, darker fins; oval body, compressed, depth contained 2.4-2.7 times in the standard length; head length 3.0-3.4 times in SL; distinctly convex dorsal head profile; nostrils subequal in juveniles, diameter of posterior nostrils twice that of anterior nostrils in 56 cm SL adults; small mouth, oblique, pair of short canines at front of each premaxilla (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

An anti-tropical species. Occurs on rocky or soft (silty-sand or mud) bottoms. The young have been observed to feed on zooplankton in the water column; feeding of adults has not yet been discovered.

Estimates based on models

Preferred temperature (Ref. 123201): 17.9 - 25.7, mean 23.7 °C (based on 53 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00553 - 0.02385), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Generation time: 6.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100).
Price category (Ref. 80766):   Very high.
