[Surface structure of the olfactory organ of marine teleosts].
By means of the electron scanning microscope, structure of the olfactory rosella has been investigated in 5 species of marine Teleostei. Among the species investigated variability in number and arrangement is observed in the olfactory rosella folds. Arrangement order of the receptor and indifferent epithelia of the fold is presented by four types. Interspecies differences in organization of the sensory epithelium is revealed in ratio of various types of receptor and secretory cells. In Teleostei flagellar olfactory cells are the most numerous. In the Limanda yokohamae sensory epithelium certain flagella are described, that essentially differ by their size from usual receptor flagella and, evidently, are their complexes. The secretory cells are found in indifferent and sometimes in sensory epithelium as dark ostia; they are most numerous in mediosmatics. Some of the ostia are like wide craters and are, evidently, ostia of ducts of multicellular olfactory glands.
