Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 19; Anal spines: 1; Anal soft rays: 18; Vertebrae: 26. Lower lip with free ventral margin posteriorly only; head and body compressed; body elongate; nape, cheek, preoperculum and operculum almost completely covered with scales; body covered with cycloid scales, imbricate, in 105 vertical rows; mouth terminal, only slightly protractile, forming an angle of about 60° to longitudinal axis of body; maxilla reaching posteriorly to below front margin of eye; head pores all paired laterally, with 5 pores around dorsal margin of each eye; snout relatively short, rounded, its length subequal to eye diameter; anterior nostril at end of short tube; posterior nostril a simple pore; no teeth on vomer, tongue or palatines; teeth conical, slightly curved; upper jaw with two rows of small, loosely attached teeth anteriorly, teeth in outer row slightly larger than those in inner row, widely spaced; lower jaw with single row of loosely attached, small teeth directed dorsally, no enlarged curved canines visible in holotype; along outer edge of dentary a series of blunt bony dorsoventrally flattened projections with rounded tip directed more or less horizontally (widely-spaced projections appear to be bony projections of dentary, not true teeth, but probably tooth sockets), space between projections about equal to width of projections; tongue tip broadly rounded; head papillae in transverse pattern; median nuchal crest, formed by low fold of skin from first dorsal spine onto head, low; gill opening vertical, extending ventrally from pectoral-fin base below upper margin to point just below lower pectoral base, below operculum (Figure 4); fleshy interorbital subequal to diameter of eye; 2 dorsal fins, first dorsal fin VI, second dorsal fin I,19; anal fin I,18; pectoral-fin rays 19; segmented caudal rays 9+8; branched caudal rays 8+7; pelvic fins separate 1,4; vertebrae 12+14 (Ref. 83368).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245).
Resilience (Ref. 69278):  .
Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100) .
