Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12 - 13; Anal spines: 0; Anal soft rays: 8. Eye diameter less than 1.5 times in snout length, less than 1.1 times in interorbital width, and less than 5 times in head length; head length the same as body depth; lower and upper jaw close equally or lower jaw extends anteriorly from upper jaw; usually a well developed nuchal hump.

Occurs over muddy, sandy and rocky substrates (with slight preference for rocks), usually in water deeper than 3 m. Feeds on insects (both larvae and adults); small specimens also eat zooplankton, while large ones sometimes exclusively feed on fish (Ref. 35835).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00422 - 0.02065), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.47 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): Moderate vulnerability (37 of 100).
