Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Wirbelzahl: 138 - 142. This species is distinguished by the following by the following characters: tail 1.7-1.8, head 13-16, and body depth 65-73 in total length; preopercular pores 4, supratemporal canal with 5-9 pores; teeth conical, uniserial on jaws and vomer; and with a single vomerine tooth; anterior nostril non-tubular, a hole; snout is sharp, slope approximately 30° relative to underside; body colouration pinkish white, with numerous brown to orange spots that are less than eye diameter; MVF 58-140, total vertebrae 138-142 (Ref. 101270).

Captured over a rippled sand bottom. The largest female specimen (30.5 cm TL) was with ripened eggs, 0.7-0.9 mm in diameter (Ref. 101270).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
