Short description Morphology | Morphometrics

Dorsal soft rays (total): 14-15; Anal soft rays: 9 - 10. This species is distinct in having the following characters: D 14-15; A 9-10; pectoral rays 12-14; lateral-line scales 57-59; 4½ or 5 scales between lateral line and base of dorsal fin; median predorsal scales 15-16; vertebrae 59-60, predorsal 15-15.5; peritoneal spots 1-8; anterior palatine teeth of inner row longer than posterior teeth; preopercle fully scaled; posterior flap of anterior nostril leaf-like and short, just reaching or extending slightly beyond rear edge of posterior nostril when laid back; depth of body 6.6-7.45 in SL; pectoral fins reaching well posterior to a line connecting dorsal- and pelvic-fin origins, fin length 2.1-2.4 in HL; alcohol preserved color pale brown, body with 8 dark-edged brown bars, each with 3 constrictions, 2 above and 1 below lateral line; even-numbered bars darker; 2 irregular dark brown bars across lips, larger one below eye, the other just before corner of mouth; a pair of very small black spots dorsally at tip of snout, each followed by a dark brown line, the 2 lines merging posteriorly on snout; 2 dark brown spots on adipose fin; remaining fins pale, anterior dorsal fin rays with faint dark spots; when fresh, the color is orangish brown dorsally, white ventrally, white spaces between dark bars on body just above lateral line with horizontal row of 2-4 small dark brown blotches, 1 per scale ; white spaces below lateral line with 2 small interconnected vertically aligned reddish orange blotches; rows of red spots on rays of dorsal, anal and caudal fins; 2 broad black bands across lips; irregular red cross bands on caudal fin lobes (Ref. 80927).

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=0.00407 (0.00194 - 0.00854), b=3.19 (3.02 - 3.36), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.2   ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (23 of 100) .
