Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 18 - 19; Raggi dorsali molli (totale) : 9 - 10; Spine anali: 7 - 8; Raggi anali molli: 6 - 7. This species is distinguished by the following set of characters: teeth properly incisor, even in young; caudal edge of mesethmoid with a unique shape; caudal edge of supraoccipital crest straight, inclined rostrad, its height 27% of postethmoid skull length; width of posterior premaxillary expansion greater than 41% of length of the same bone; arms of articular equal in length; gut S-folded ventrorostrally in adults, anal and medial loops nearly touching; with an abrupt, steep head profile (Ref. 74403).

Inhabits both lakes and rivers. Proliferates in rivers with medium to high velocities. Found between 35 and 535 m elevation (Ref. 36880). Feeds on aufwuchs which cover rocks and submersed trees and filaments of algae.

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Spawns in caves. During spawning both parents completely change their color.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02042 (0.00927 - 0.04498), b=3.11 (2.92 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec=50-60).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
