(See ETYFish); oxyrhynchus: oxys (Gr.), sharp; rhynchus (L.), snout, referring to its elongated, pointed and narrow snout [authorship often attributed to Müller & Henle, who published Valenciennes’ description].

Estimates based on models

Preferred temperature (Ref. 115969): 27 - 27.8, mean 27.5 (based on 149 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00468 (0.00218 - 0.01003), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.5 ±0.80 se; based on food items.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (K=0.11-0.12; tm=5-7; tmax=12; Fec=4).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (74 of 100).

Catégorie de prix (Ref. 80766): Medium.
