Eulimids snails are renowned for their parasitic habits on Echinodermata. These gastropods can be ectoparasites, endoparasites and some groups are able to make gall in their host. This is the case of the Caribbean eulimid Sabinella troglodytes, which lives in association with the cidaroid sea urchin Eucidaris tribuloides. The present work describes the lifecycle of S. troglodytes, studied in situ over four years and reports on unprecedented data on the species' reproductive behaviour. During the dry season, from September to March, most galls are occupied by couples of snails and newly laid egg masses. In observations during the wet period of the year, May to August, adult specimens are rarely found and juvenile stages can be observed whilst settling and crawling the spines. The feeding mechanism can also be observed in live specimens maintained in the laboratory indicating that the snails erodes the epithelium and the calcareous matrix as well. Finally this work also records for the first time the occurrence of S. troglodytes in the South Atlantic Ocean, extending its range of distribution, previously restricted to Florida and Caribbean, to Brazil.
