  • Current distribution known : C. taenia is one of the most widely distributed freshwater fish species in Eurasia. It ranges across Siberia, central Russia, and Europe into England and to the southern end of the Iberian Peninsula. It occurs in Italy, and is one of the few native freshwater fishes on Sicily. The southern limits of its distribution in eastern Asia, which may overlap with the ranges of other species of Cobitis, is poorly known. In Africa it is known only from the Sebou drainage in the Rif Mountains, adjacent to the Strait .
  • Food habits / trophic level : filters sand for food particles .
  • Habitat / home range : adults occur in slow-flowing and still waters with fine sandy substrate. They occur in the Baltic Sea at salinities of up to 5 ppt. Nocturnal, stays hidden under rocks or buried in the sand or mud during the day .
  • Morphology / anatomy : Vasil'ev et al., 1989 .
  • Reproduction : oviparous, with distinct pairing during breeding. Spawn in spring; scatters eggs into mats of plant material. Eggs are found attached to gravel and weed in shallow, flowing water. Larvae hide under vegetation and in debris until beginning of exogenous feeding. Start of courtship is observed when both male and female swim excitedly then progresses to a chase done by the male. When movements become synchronised, the male entwines itself around the female's body, squeezing it and causing egg spawning. Triploid females can occur; they produce triploid eggs which can develop without fertilization, but need contact with sperm to start development (gynogenesis) .
