Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0. Upper eye less than its own diameter from dorsal profile of head.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00896 - 0.01471), b=2.98 (2.91 - 3.05), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.45 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.37; tm=3; tmax=14).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100) .
Price category (Ref. 80766):   Very high.
