Data are presented relative to an epidemic die-off of wentletraps, Epitonium clathratulum, under aquarium conditions. Snails, each connected to the end of a self-produced elastic filament uniting a bunch of egg capsules, were observed to become separated from their shells, implicating detachment/atrophy of the columellar muscle. This phenomenon, as well as the die-off itself might represent a normal post-reproductive event, E. clathratulum possibly being an annual species. 5 pp., 1 fig., gr. 8.…

A review is given of the most important literature on parasite/host (or predator/prey) relations of Epitoniidae and Anthozoa, and various modes of feeding are mentioned. An as yet unreported association of the wentletrap Epitonium clathratulum and the sea anemone Bunodosoma biscayensis is described. Both species were collected at Plage d'Ilbarritz, Cote Basque, SW. France. Field and aquarium observations suggest that E. clathratulum feeds on partly digested food in the gastric cavity of its host-anemone. This is achieved in a way as yet unprecedented: the wentletrap climbs the oral disc of its host and introduces its proboscis through the mouth slit into the gastric cavity of feed. The sequence of climbing the host and feeding is described and depicted. 14 pp., 12 figs, gr. 8. …
