Greater Bermuda Land Snail (Poecilozonites bermudensis)

The Greater Bermuda Land Snail was considered extinct by the early 1990's, until its rediscovery by a member of the public in 2014. Live specimens were immediately sent to the London Zoo for ex-situ management and in 2016 the Chester Zoo (UK) began a large scale breeding programme which has resulted in thousands of snails being returned to Bermuda and reintroduced to island nature reserves where threats can be controlled.

This species is endemic to Bermuda and is listed as Critically Endangered, as per IUCN criteria, under the Protected Species Act 2003.
