Zachrysia provisoria, the Cuban brown snail;
Monroe county, Florida (11 June 2016).
The Cuban brown snail is a non-native terrestrial species that is now well-established in parts of Florida and many other pockets of the Western hemisphere. They can be potentially problematic for agricultural centers and are considered to be invasive (not merely non-native). This one was photographed in the Florida Everglades.
