In this study, we examined the olfactory epithelium (OE) of the barfin flounder by transmission electron microscopy. As in the case of the ordinary teleost, the OE of the barfin flounder had 3 types of olfactory receptor cells (ciliated olfactory receptor cell, microvillous olfactory receptor cell and crypt cell), 3 types of supporting cells (ciliated, microvillous and crypt supporting cells) and basal cells. Each type of OE cells in the barfin flounder had similar ultrastructure to that of the ordinary teleost. Crypt cell is the third type of olfactory receptor cell unique to fish, whose function is unclear. The barfin flounder may be a suitable material to study crypt cells because it has relatively abundant crypt cells in the OE.
