Résumé / Abstract

Dyakia striata, a snail found in Singapore and Malaysia, is the only terrestrial mollusc known to be luminescent. It produces flashes of light by means of a discrete luminescent organ in the head-foot. Previous studies of D. striata emphasized juvenile snail luminescence and its loss with sexual maturity. We, however, subsequently discovered that luminescence persisted in large snails that were probably adults. Here, the gross and ultrastructural anatomy of the reproductive system and the luminescent organ were compared between three snail categories: small snails with a luminescent organ, large snails with a normal luminescent organ, and large snails incapable of luminescence. We found that loss of luminescence did not coincide with sexual maturity
