Knipowitschia ephesi
Overview
Knipowitschia ephesi, the Ephesus goby, is a species of goby endemic to the delta and marshes of the lowermost Küçük Menderes in western Anatolia, Turkey.Turkey where it occurs in stagnant or nearly stagnant fresh waters. Its habitat is threatened by water abstraction, pollution, and destruction and these have an impact on this species, leading to the IUCN to classify it as Critically Endangered. The specific name refers to the ancient, ruined city of Ephesus which was a port located at mouth of the Küçük Menderes.
Knipowitschia ephesi faces severe threats from habitat degradation in its extremely limited range around Ephesus, Turkey. Urban development and tourism infrastructure have significantly altered the coastal wetland systems this endemic goby depends upon. Water pollution from agricultural runoff and sewage discharge has degraded water quality in remaining habitat patches. The species' tiny population size makes it exceptionally vulnerable to any further habitat loss or environmental changes.
Habitat
This endemic goby inhabits shallow coastal waters, brackish lagoons, and associated wetland systems in the Ephesus region of western Turkey. The species requires specific salinity levels and vegetation cover found in these transitional marine-freshwater environments.
