Descripción: National Museum of Natural History. Smithsonian Institution.
«Strange as it may seem, fossil slitnails were known long before any living specimen was ever found, and the fossils are some of the earliest known gastropods dating back hundreds of millions of years to the Paleozoic. Back in 1856, a hapless hermit crab wearing a slitsnail on it's back crawled into a fish trap and the following discovery that "fossil" organisms were alive was received by a wave of enthusiasm. Science aside, this is a fantasy come true--living fossils!»
