Short description Claves de identificación | Morfología | Morfometría

This species is distinguished by the following characters: elongated and compressed body; rounded snout, slightly protruding over tips of jaws; fully scaled head, body scales larger than those on head with 20 in an oblique row; no basibranchial tooth patches; dentigerous vomer a minute, circular plate; sagittal otolith with distinct pointed process at the anterior end; 29 pectoral fin-rays; ventral fins almost reaching anus, 17.5% SL); 10 long gill rakers on anterior arch; chocolate brown coloration (Ref. 84269).

Known only from the holotype, a semi-ripe, female caught at continental slope depth. Stomach and intestine remains indicate that the species feeds on or close to the bottom (remains of crustaceans: 7 amphipods (10 - 40 mm in length) and 1 isopod ca. 10 mm in length (Ref. 84269). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [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).

Nivel trófico (Ref. 69278): 3.6 ±0.6 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).
