deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 5 - 7; duri punggung lunak (Keseluruhan (total)) : 15 - 16; Duri dubur: 0; Sirip dubur lunak: 11 - 13; vertebrata, bertulang belakang: 30. Differs from other species of Cottusin France by the combination of the following characters: in juveniles and adults, prickling on body extending backwards to caudal peduncle; no distinct transverse bands on pelvic; last dorsal-fin ray reaching rudimentary caudal-fin rays; eye diameter 27-31%; interorbital distance 1.9-2.4 times in eye diameter; last anal-fin ray connected to body by a membrane along about 2/3 of its length; depth of caudal peduncle 24-28% HL (Ref. 55856). Caudal fin with 13 to 16 rays (Ref. 40476).
Found in cold, karstic spring (Ref. 59043). Laboratory experiments, using natural photoperiod and constant temperature of 15-16°C corresponding with those of its habitat, showed that a female could lay eggs several times with less than one month interval. Between 20 to 70 eggs of relatively large size (2.1 mm) are laid (Ref. 30578).
