Th e freshwater bryozoan Pectinatella magnifica (Leidy, 1851) was found for the fi rst time in the Ukrainian part of the Danube Delta (Poludionniy arm, 45°25'00" N, 29°45'25" E) in 2005. Since then, it has increased in abundance. The greatest colony numbers occurred on both dead and living reed stems in the delta region 1.5–2.0 km upstream from the Black Sea.
