Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0 - 4; Dorsal soft rays (total): 16 - 20; Anal soft rays: 15 - 19. Head and anterior body depressed. Body scales minute, randomly arranged. Pectoral fins with "squarish" appearance, dorsoposterior margin straight, middle ray longest. A mental barbel present on chin. Respiratory valve inside lower jaw with a dermal appendage expanded vertically in young, without appendage in adults. Both lips with labial fimbriae. Lower portion of body without dermal folds originating from anal fin rays (Ref 42788).

Ranging from estuaries to the continental shelf (Ref. 42788). Feeds on demersal fishes (Ref. 42788). Minimum depth range from Ref. 121942.

Estimates based on models

Preferred temperature (Ref. 123201): 12 - 20.6, mean 16.6 °C (based on 64 cells).

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

Bayesian length-weight: a=0.00617 (0.00263 - 0.01447), b=3.11 (2.90 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 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 to moderate vulnerability (35 of 100).

Price category (Ref. 80766): Unknown.
