Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 53 - 57; Anal soft rays: 41 - 46. Distinguished by the following: serrated frontal crest with united, bur slightly emarginate pelvic fins; total elements in dorsal fin 53-57; total elements in anal fin 41-46, pectoral-fin rays 14-17; pelvic-fin rays I, 3-5; anal-fin pterygiophores preceding the first hemal spine (AP) 3-4; caudal vertebral count 23-25; longitudinal scale rows 48-66 (Ref. 078624).

This species was collected at depths of 62-65 in the Arafura Sea and 50-70 m from the Samar Sea; possible that this species may be confined to deeper waters than most other members of this subfamily (Ref. 78624).

Estimates based on models

Preferred temperature (Ref. 123201): 14.4 - 28.2, mean 27 °C (based on 220 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00398 (0.00219 - 0.00722), b=3.00 (2.84 - 3.16), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
