black sea red data book - Department of Biology

Biology. Polycyclic development during the warm season of the year. The prehensile
mouth parts suggest raptorial feeding on small invertebrates.
Population trends. The habitat and distribution pattern provide a rare case where the
activity of man (the damming of the Dnieper) benefitted the preservation of a rare
species.
Threats. Pollution of irrigation systems and eutrophication, causing hypoxia in the
bottom layer of water.
Conservation measures taken. None.
Conservation measures proposed. Include in the Black Sea Red Data Book. A
reduction of water reservoir pollution.
