Bermuda Land Snails (Poecilozonites sp.)
The genus Poecilozonites contains at least 4 species of snails, all of which are endemic to Bermuda. Two of them, Poecilozonites nelsoni and Poecilozonites reinianus are extinct. The two surviving species are Poecilozonites circumfirmatus and Poecilozonites bermudensis, which are rare in Bermuda.
Lesser Bermuda Land Snail (Poecilozonites circumfirmatus)
A small population of P. circumfirmatus were sent to the Zoological Society of London (ZSL) where they have been successfully bred. You can read about the project on ZSL's website.
Poecilozonites circumfirmatus is considered Critically Endangered and is listed under the 2003 Protected Species Act.
Greater Bermuda Land Snail (Poecilozonites bermudensis)
Poecilozonites bermudensis is a slightly larger snail than the species above, reaching about the size of a Bermuda 5 cent coin.
