The article presents sessile ciliates (Ciliophora) found during first studies of biological diversity of the underwater part of the artificial canal, created in the middle of the 20th century on the western shore of the Balaklava Bay (Sevastopol, the Black Sea), and the natural coastal Catherine Grotto (Cape Aya, the Black Sea). In total, 4 species of ciliates were found, one of which Cothurnia ovalis Kahl, 1933, is new not only for Balaklava Bay, but for the Black Sea. Description of the species, their systematic position, morphometric characteristics and information about their distribution are given.
Two species of sessile ciliates from subclass Peritrichia, Vorticella pyriforme and Zoothamnium sinense, new for Black Sea, were found in the Kruglaya Bay (the Black Sea) on algae Cystoseira crinita and Cladophora sericea. The article provides a description, systematic position and data on the distribution of the collected species.
