Short description Morphology | Morphometrics

Anal soft rays: 11. Can be distinguished from other species of Cottus in the Adriatic basin and Danube drainage by the combination of the following characters: body coloration uniform reddish brown, or pattern slightly darker than background; fins hyaline or dusky and rays slightly tessellated; first dorsal fin dark brown to black with bold whitish margin in live nuptial males; no prickling on body; depth of caudal peduncle 22-26% HL; body depth at origin of second dorsal fin 16-17% SL; predorsal length 33-38% SL; length between snout and origin of second dorsal fin 52-59% SL; usually 11 1/2 anal-fin rays; pelvic-fin base attached to body by a small membrane; interorbital distance 1.5-2.0 times in eye diameter; last anal-fin ray attached to body at base only; membrane of first dorsal fin usually reaching to origin of second dorsal; length of caudal peduncle 45-62% HL; dorsal head length 21-25% SL (Ref. 55856).

Biology     Glossary (e.g. epibenthic)

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00349 - 0.02279), b=3.12 (2.89 - 3.35), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (14 of 100) .
