Common names: Russ: Ifiginella koluchkonogaya; Ukr: Ifiginella kolyuchkonoga
Taxonomic descriptions: One of the 3 species of the endemic Black-Caspian Seas genus. Propoduses of I-V pereiopods are half nipping claw shaped; the claw is very short, slightly longer than the width; the lower ventral corner of the third epimeral plate is elongated and sharp.
World level: VU (Endemic of the Azov-Black Sea basin)
Black Sea Regional level: VU
Subregion level: VU (Ukrainian sector)
Distribution: Inhabits the lower reaches of the Danube, Dniestr, Dniepr and South Bug including the Dnieprovsky, Dniepr-Bug and Kuchurgansky limans. Encountered in rivers of the Sea of Azov. Range includes the Caspian Sea basin.
Habitats type, Critical habitats, Limiting factors: Fresh water and brackish parts of limans, deltas and rivers. The main biotopes are silty-sandy, silty-rocky and muddy-sandy sediment.
Biology: Oligohaline and freshwater species tolerant to significant variations in water temperature. Inhabits as a rule the coastal zone of water bodies. Commensal with the river crawfish Astacus leptodactylus. Adults organisms have a length 8-9 mm.
Population trends: Low abundance (1-3 ind/m2).
Threats: Water pollution, erosion of shores.
Conservation measures taken: Included in Red Data Books of Ukraine and the Black Sea.
Conservation measures proposed: Reduction in Black Sea coastal zone pollution. Study of biological peculiarities of the species, protection of characteristic biotopes, including the Danube, Dniestr and Don deltas.
