Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 10; Vertebrae: 24. This species is distinguished by the following characters: D XII,10; A III, 10; pectoral-fin rays 14; scale rows above lateral line 5, below 11; pored lateral-line scales 47-48; gill rakers 6 + 1 + 12 = 19; second anal-fin spine (2AS) is much larger than 3AS, the length of 3AS 1.34-1.41 in 2AS; incisor-like teeth has five points, all points subequal in size, forming a flat cutting edge at each incisor-like teeth (Ref. 94712).

Apparently feeds on algae (based on unique teeth formation) (Ref. 94712).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02089 (0.00983 - 0.04439), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 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. 59153): Low vulnerability (10 of 100).
