Biphally in Biomphalaria glabrata (Say, 1818) (Pulmonata, Planorbidae)

Abstract

We describe a biphallic specimen of Biomphalaria glabrata (Say, 1818) from the municipality of Caeté, State of Minas Gerais, Brazil. The conformation of the two penial complexes, with a common genital pore on the left side. suggests that both have copulatory capacity. Based on a review of literature type of biphally appears to be reported for the first time in planorbids.
