Abstract

The gross morphology of the olfactory organ and eye size in 5 genera and 15 species of barbeled cyprinid fishes was analyzed morphometrically. Large size of nostrils and large number of olfactory lamellae are correlated with turbid or silty habitats, whereas smaller nostrils and fewer lamellae are characteristic of clear-water species. There does not appear to be much correlation between the size of the olfactory organ and habitat. No species-specific correlation between eye size and habitat was discerned, and there is no apparent correlation between eye size and extent of development in the olfactory organ.
