背棘 (总数) : 5 - 7; 背的软条 (总数) : 15 - 16; 臀棘: 0; 臀鳍软条: 11 - 13; 脊椎骨: 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).
在法国有别于其他 Cottus 的种藉由下列特征的组合: 在稚鱼与成鱼中, 在向后延伸到尾柄的身体上刺; 没有在腹鳍上的明显的横纹; 最后的背鳍鳍条达到不发达的尾鳍鳍条; 眼直径 27-31%; 眼间距 1.9-2.4 倍眼直径; 连接到身体的最后臀鳍鳍条经由一个膜沿着大约它的长度中的 2/3; 尾柄 24-28% HL 的深度.(参考文献 55856) 尾鳍有 13 到 16个鳍条。 (参考文献 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).
实验室实验, 使用自然光周期与以它的栖息地的符合的 15-16 °C 的持续温度, 显示一条母鱼以少于一个月间隔可以好几次生下卵。 在相当大大小 (2.1 mm) 的 20 到 70个卵之间生产。 (参考文献 30578)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
