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).
Common species (Ref. 34024). Based on stomach radiographs, contents include crustaceans, gastropods, remains of polychaetes, and detritus (Ref. 80689). Oviparous, with planktonic larvae (Ref. 36413). Oval, pelagic eggs float in a gelatinous mass (Ref. 205).

50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00156 - 0.01061), b=3.12 (2.90 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic Level (Ref.
69278): 3.6 ±0.51 se; Based on food items.
Resilience (Ref.
