Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 79-86; Anal spines: 0; Anal soft rays: 59 - 67. Tip of isthmus below middle of lower eye. Scales on ocular side ctenoid, armed with a row of hairlike spines. Caudal fin with 3 simple rays on upper and lower margins respectively. Pectoral fin elongated into a filament, longer than head. Caudal fin without a dark band. In male, body on blind side stained with dark-blue except for head, interorbital width broader and pectoral fin longer than in female.

Lives on sand and shell bottoms and feeds on bottom-living animals. Sexually dimorphic characters develop at about 5 cm SL.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00442 - 0.02369), b=3.00 (2.81 - 3.19), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.5 ±0.37 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100) .
