Short description Claves de identificación | Morfología | Morfometría

Radios blandos dorsales (total) : 6; Radios blandos anales: 4; Vértebra: 18 - 19. Body relatively firm, skin tough. Large tubercles with rows of bosslike spinules radiating out from the central spine along the ridges between facets (as seen in D. atlanticus like shagreen). Jaw relatively long compared to D. atlanticus, 14.6% of SL. Cephalic lateral-line counts: subopercular 6, preopercular, 2. Tail lateral-line counts 12-15. Fin-rays with fine tubercles on dorsal and caudal fins and dorsal side of pectoral fins, running out for about half the length of the fin ray. Ventral surface of pelvic fin rays have tubercles near fin base. Paired fins relatively slender with fin membranes transparent (Ref. 40826).

Estimates based on models

Preferred temperature (Ref. 123201): 8.4 - 11.4, mean 9.5 °C (based on 5 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02344 (0.00968 - 0.05678), b=2.94 (2.73 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.3 ±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): Low vulnerability (10 of 100).
