Short description Morphology | Morphometrics

Dorsal spines (total): 9 - 16; Dorsal soft rays (total): 18-20; Anal spines: 1; Anal soft rays: 28 - 29. Caudal moderately forked (Ref. 6885). Light brown on dorsal surface, silvery ventrally, dark along midside, mid-dorsal line in irregular patches, and lateral line; spinous dorsal with dark streaks paralleling free edge; upper parts of pectorals and caudal with darkened edges, and vague dark blotches on rayed dorsal; anal, pelvic fins, and lower parts of pectorals light (Ref. 6885).

Biology     Glossary (e.g. epibenthic)

Adults are found in deeper waters whereas larvae and juveniles occupy shallow, nearshore habitats (Ref. 57910). Usually buried in muddy or sandy bottoms with mouth protruding (Ref. 2850). Eggs are laid in a gelatinous mass that is attached to rocks (Ref. 2850). Some have been caught by hand in shallow water (Ref. 2850).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Incubation of eggs takes one year (Ref. 57910).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 1 - 7.6, mean 4.1 (based on 434 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 1.2500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.3 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 1,000).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (25 of 100) .
