Аннотация: The structure of the olfactory organ in scissortail sergeant Abudefduf sexfasciatus was studied. Smaller specimens with a total length of <30–35 mm have two nostrils, while larger fish retain only the posterior one. The olfactory rosette is arrow-shaped, oval; the total number of lamellae devoid of secondary folding increases with the growth of the fish, but does not exceed 15 (with a total length of 145 mm). Two ventilation sacs adjoin the olfactory cavity: a large lacrimal sac, consisting of two compartments of unequal size, and an ethmoid sac that is much smaller in volume. The scheme of ventilation of the olfactory cavity is proposed. Comparison of the macromorphology and ventilation of the olfactory organ of A. sexfasciatus and thepreviously studied A. vaigiensis, along with obvious similarities, also reveals differences, the causes of which may be related to the structure of the head skeleton and the feeding modes of these fish.
