Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 5 - 6. This species is distinguished by the following characters: ventral surface fully naked and interspaces of principal bucklers on dorsal surface lacking dermal spinules: D 5-6 (mainly 6); pectoral-fin rays 13; blunt subopercular buckler with a stout anterior-directed spinelet usually present; rostral spine directed rather more upward than forward; relatively few and loosely arranged bucklers; all bucklers are blunt; appressed anal fin reaching caudal fin base; it is the smallest species of the genus reaching 51.1 mm SL in adults (Ref. 92977).

Maximum depth from Ref. 106682.

Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 4.1, mean 3.2 °C (based on 354 cells).

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).

Trophic level (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

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).
