Short description Morfologia | Morfometria

Raggi anali molli: 11 - 14. Can be distinguished from other species of Cottus in Europe by the combination of the following characters: lateral line incomplete; reaching to anal-fin base, usually with 17-25 pores; at vertical of 10th ray of second dorsal fin, lateral line clearly above horizontal midline, distance from dorsal midline to lateral line 1.5-2.1 times in distance from ventral midline to lateral line; no distinct transverse bands on pelvic fin; prickling on body variable, in juveniles usually extending to caudal peduncle (Ref. 55856).

Biologia     Glossario (es. epibenthic)

Inhabits medium-sized rivers to small streams, and lake shores (Ref. 59043).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00344 - 0.02310), b=3.12 (2.89 - 3.35), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.5 se; Based on size and trophs of closest relatives
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (35 of 100) .
