Etymology: Cottus: Greek, kottos = a fish (Ref. 45335);  rondeleti: Named in honor of Guillaume Rondelet (1507-1566), precursor of European ichthyology and author of one of the very first ichthyological treaties (1554-55)..   More on author: Freyhof, Kottelat.

Short description Morphology | Morphometrics

Anal soft rays: 10 - 11. Differs from all other species of Cottus in France by having only 10-11 1/2 anal-fin rays. Other characters useful in the identification: posterior tip of second dorsal fin reaching rudimentary caudal-fin rays; no transverse bands on pelvic fin; lateral line complete, with 30-33+1 pores; 13 pectoral-fin rays; no prickling on body; length of caudal peduncle 58-71% HL; depth of caudal peduncle 26-32% HL; predorsal length 34-37 % SL; distance from tip of snout to origin of second dorsal fin 54-57% SL; preanal length 54-58% SL; first and second dorsal fins slightly to moderately joined; snout pale; first dorsal fin with very dark base (Ref. 55856).

Biology     Glossary (e.g. epibenthic)

Inhabits small stream with clear, swift water and stone bottom (Ref. 59043).

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=0.00871 (0.00341 - 0.02227), 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):  3.2   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100) .
