Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 135-148; Anal spines: 0; Anal soft rays: 101 - 112; Vertebrae: 77 - 88. This species is distinguished and differs from S. crassus by the following characters: number of dorsal-fin rays 135-148 (121-139), anal-fin rays 101-112 (vs. 91-102), total vertebrae 77-88 (vs. 71-78), otolith ostium depth in % of sulcus length 19-29 (vs. 30-40) (Ref. 80689).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00338 (-0.17662 - 0.18337), b=3.16 (3.05 - 3.26), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.51 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High to very high vulnerability (74 of 100) .
Price category (Ref. 80766):   Medium.
