PROTANDRY WITH ONLY ONE SEX CHANGE IN AN EPITONIUM (PTENOGLOSSA)

Abstract
Reports conflict on whether ptenoglossans undergo more than one sex change, although since 1926 they were always reported (with few supporting data) to be protandric. Small individuals of the West Indian wentletrap Epitonium albidum (Orbigny, 1842) (shell length <8 mm) were found to be males (with spermatozeugmata in their gonads), and large individuals (shell length >7 mm) were females (with oocytes and ova). Hermaphroditic individuals ranged in shell length from 5 to 8 mm. The data support the idea of protandry with only one sex change in E. albidum. Males and females attain larger sizes in the British Virgin Islands than at Barbados.
