Short description Morphology | Morphometrics

Body moderately slender and compressed; head large and pointed; teeth caniniform, enlarged, and somewhat crooked, two anterior pairs in each jaw; dorsal fin continuous, with 11 spines; lateral line slightly arched, with 28 scales; body reddish pink; belly paler; a black spot on the flank above posterior edge of pectoral fin; anal fin white (Ref. 55763).

Biology     Glossary (e.g. epibenthic)

Lives over sandy bottoms with gravel and isolated reefs. Often caught in the open sea as a by-catch of trawlers fishing for prawns and shrimps. Each individual functions first as a female but later changes to a male (Ref. 47122).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00445 - 0.02048), b=3.05 (2.87 - 3.23), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (35 of 100) .
Price category (Ref. 80766):   Very high.
