Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 6; Dorsal soft rays (total): 13; Anal soft rays: 13; Vertebrae: 26. This species is distinguished from its congeners by the following set of characters: D VI,13 segmented rays; A 13 segmented rays 13; pectoral-fin rays 14; head large 30-31% SL; pectoral fin long, reaching past end of pelvic fins, its length 18-21% SL; caudal fin long 21-24% SL; snout short 5-9% head length; slightly protruding lower jaw, posterior end of jaws reaching posteriorly to or beyond vertical at anterior oculoscapular canal pore F?; tip of upper lip with a small anteriorly directed skin projection; reduced longitudinal pattern of sensory-papillae rows; rounded caudal fin; with 6 large black blotches along lateral midline of body; spinous portion of dorsal fin with a cospicuous black curved mark along entire edge (Ref. 93255).
Inhabits coral sandy bottoms of bays at depths of 5-12 m. They live on bottom, crawl into bottom directly and push out a head from the bottom (Ref. 93255).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
