Bermuda Land Snails (Poecilozonites sp.)

Poecilozonites snails are commonly seen as fossils in Bermuda

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.

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.
