Description

The Acheron spring goby is a minuscule goby of the family Gobiidae reaching about 2.6 cm, among the smallest fish in Europe. The light-brown body bears a few dark cross-bars; like other gobies the pelvic fins are fused into a sucking disc. The species is endemic to a few clear, constant springs and spring-streams of the Acheron in western Greece, with an extremely small range of only a few tens of square kilometres. Among the water plants it searches for very small zooplankton and small invertebrates. The male guards the eggs laid among plants. Because of its minuscule range it is highly sensitive to water abstraction and degradation of the springs, and is assessed as Critically Endangered (CR).
