Short description Identification keys | 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 based on models

Preferred temperature (Ref. 123201): 9.7 - 21.8, mean 18.2 °C (based on 160 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00408 - 0.02036), b=3.04 (2.85 - 3.23), 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. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
