Short description Identification keys | Morphology | Morphometrics

Diagnosis: high number of gill-rakers on lower outer arch (32-38); long head, 35.6-40.6% of standard length, and correlated with this a more posterior position of dorsal, pectoral and pelvic fins; long premaxillary pedicel, 33.0-38.4% head length (Ref. 55925).

Inhabits rocky areas with a deposit of fine sediment (Ref. 267, 55925), but also found on soft-bottom habitats (Ref. 55925). Feeds on small invertebrates, mainly benthic copepods (Ref. 267, 55925) obtained by sucking up the fine sediment and passing it over the gill-rakers (Ref. 267).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.00 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.
