Abstract

A high degree of ultrastructural diversity in cyprinid maxillary barbels was revealed by scanning electron microscopy. The following genera were surveyed: Campostoma, Couesius, Erimystax, Exoglossum, Extrarius, Hybopsis, Macrhybopsis, Nocomis, Notropis, Oregonichthys, Phenacobius, Pimephales, Plagopterus, Platygobio, Rhinichthys, and Semotilus. Taste buds were found to be supported by elongate papillae in some species of Erimystax and Platygobio gracilis. Barbels of the species of Nocomis examined here have taste buds borne on prominent ridges. Barbel ornamentation ranged from a dense arrangement of conspicuous taste buds for Macrhybopsis gelida to a sparse distribution of minute taste buds for Notropis harperi.
