| Résumé : | The endemic snails of the Galápagos are threatened—by introduced fire ants, by black rats and by the destruction of the Scalesia forest that is home to many of them. More than 30 endemic bulimulid snails are now considered endangered there, many of them occurring only in the 10 per cent of the Galápagos that does not have national park status. The problems of protecting them are formidable, and failure would mean the loss not only of individual species, but of a rare opportunity to study speciation in a natural laboratory. © 1987, Fauna and Flora International.
