Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 4 - 6. This species is distinguished by the following set of characters: D 4-6; pectoral-fin rays 10-13; rostrum pointed, needle-like, base small; subopercular buckler with few weakly-developed spinelets; small bucklers loosely covering posterior part of skull; orbit large (14.1%-16.8% SL); rostrum short (7.1%-11.2% SL), directed upward rather than forward; interorbital space is narrow (5.4%-7.1% SL); body covered with relatively sharp bucklers, in loose arrangement; interspaces between bucklers naked; OD/IO = 2.3-2.8, OD/RL = 1.3-2.1; anal fin not reaching caudal-fin base when fully appressed (based on short rostrum specimens only) (Ref. 123774).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [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).
