Short description Morphology | Morphometrics

Dorsal soft rays (total): 97-99; Anal soft rays: 81 - 83; Vertebrae: 57 - 59. Distinguished by having the following combination of characters: presence of 10-15 soft serrations and absence of spines on the posterior margin of preopercle; snout almost twice as long as horizontal diameter of pigmented eye; horizontal eye window 2.5-2.7% SL; two median and in the holotype also a pair of small basibranchial tooth patches; 10-11 developed rakers on anterior gill arch; sagittal otolith with undivided sulcus; and sulcus-length in percentage of sagitta-length 50-55 (Ref. 78399).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00338 (-0.17662 - 0.18337), b=3.15625 (3.05302 - 3.25948), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.4 ±0.5 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 (16 of 100) .

Price category (Ref. 80766): .
