Heterotrophic flagellates and centrohelid heliozoa from littoral and supralittoral zones of the Black Sea (the Southern part of the Crimea) |
Papanin Institute for Biology of Inland Waters, Russian Academy of Sciences, Borok, Russia | Submitted September 26, 2017 | Accepted October 10, 2017 | Summary Species composition and morphology of heterotrophic flagellates and centrohelid heliozoa in littoral and supralittoral zones of the Black Sea in the Southern part of the Crimea were studied. Overall, 68 species of heterotrophic flagellates and 2 species of centrohelids were encountered in this survey, of which 44 species are the first records for the Black Sea. Many species are widespread and known not only from marine but also from freshwater and soil habitats. Most observed species feed on bacteria, 14 species consume other protists (heterotrophic flagellates, algae, and naked amoebae). Micrographs and morphological descriptions of 20 species (Multicilia marina, Salpingoeca abyssalis, Salpingoeca infusionum, Stephanoeca diplocostata, Paraphysomonas cylicophora, Clathromonas butcheri, Protaspa tegere, Protaspa verrucosa, Helkesimastix marina, Heteronema ovale, Petalomonas labrum, Gweamonas unicus, Pendulomonas adriperis, Platychilomonas psammobia, Zoelucasa sablensis, Planomonas cephalopora, Planomonas melba, Amastigomonas muscula, Choanocystis aff. minima, Raineriophrys raineri) are given.
Key words: heterotrophic flagellates, centrohelid heliozoa, protists, species diversity, morphology, Black Sea, Crimea
