Morphology | Morphometrics
spines: 0. Snout long and sharply pointed, its anterolateral margin almost completely supported by bone. Underside of the head entirely naked; the dorsal surfaces of the head with broad areas behind the anterolateral margins either naked or with small, thin scales.

Estimates based on models
Preferred temperature (Ref. 115969
): 4.2 - 8.5, mean 6.7 °C (based on 112 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00229 (0.00102 - 0.00516), b=3.15 (2.96 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.65 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (55 of 100) .
