Differences in Inhalant Siphonal Papillae among the Japanese Species of Corbicula (Mollusca : Bivalvia)

Three common species of Japanese Corbicula are shown to differ in their morphology of the inhalant siphonal papillae. They are predominantly simple and least in number in freshwater Corbicula leana, predominantly simple but more numerous in brackish Corbicula japonica, and variable in shape and deci...

Description
Summary:Three common species of Japanese Corbicula are shown to differ in their morphology of the inhalant siphonal papillae. They are predominantly simple and least in number in freshwater Corbicula leana, predominantly simple but more numerous in brackish Corbicula japonica, and variable in shape and decisively most numerous in Corbicula sandai of Lake Biwa-ko. Corbicula insularis from Shirahama and Corbicula fluminea from Hong Kong are also compared. Shell morphometries are provided for the representative samples of four species from Japan. The taxonomy of the three Japanese species is reviewed briefly.
