Those dinoflagellates founs in the Black Sea. I think they are Prorocentrum, but could not saythe exact specific name. May be they belong to P. compressum.
Does anybody know the specific name of that dinoflagellates (Prorocentrales)?
anton, variation is obvious but somewhat the same as in p. minimum. at present, w/o molecular biology, only god knows... i believe that widely distributed species most likely represent a species complex, and p. compressum is one of them, so we are talking about the same morpho-species.
