Short description Morfologia | Morfometria

This species is distinguished by the following characters: elongate body with an elongate, broad and paddle-shaped pointed snout extending anterior to head (SNL 47.7% HDL), tapering to a slender tail; the junction of supraorbital and infraorbital canals on ventral side of snout is closer to the tip of the snout than to the nasal canal; ONC/TIO is greater than 1.4 (ONC/TIO= 1.64); TIO/SWF is less than 1.5 (TIO/SWF= 1.47); TIO/LNC is less than 3.0 (TIO/LNC= 2.75); tooth-plates are nearly smooth; eyes are relatively small (EYL 6.4% BDL), distinctly behind level of mouth; the first and second dorsal fins are separated by a relatively long interdorsal space (IDS 23.6% BDL) and not connected by a web of skin; caudal-fin axis weakly raised with the fin asymmetrical, the epaxial caudal-fin lobe narrower than hypaxial lobe; dorsal caudal tubercles 25; caudal filament vestigial; coloration uniformly dark brown across entire body, except the oronasal region which is abruptly paler than the body (Ref. 97389).

Estimates based on models

Preferred temperature (Ref. 115969): 2.1 - 8.2, mean 5.5 °C (based on 195 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6289   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00245 (0.00098 - 0.00614), b=3.14 (2.91 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Assuming Fec <100).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (51 of 100) .
