Discovery of New Species of Dinoflagellates in the Pelagic Zone of the Northeastern Part of the Black Sea

In the northeastern part of the Black Sea, dinoflagellate species new for this area have been recorded: Oxyhysis oxytoxoides, Spatulodinium pseudonoctiluca, Scaphodinium mirabile, and Actiniscus pentasterias. These species, previously indicated only for the waters of Bulgaria, Romania, Turkey, Georgia, Ukraine, and Crimea, have been found in the pelagic zone of the northeastern part of the Black Sea over the past two decades: in the area from Abkhazia to the Kerch Strait.
