involváris

Involvarius is a genus of small to medium-sized, terrestrial snails, specifically pulmonate gastropod mollusks in the family Achatinidae. The genus is native to the Caribbean region, with species found in Cuba, Jamaica, and the Cayman Islands. Involvarius species are characterized by their distinctive, involute (rolled) shells, which are typically brown or reddish-brown in color. The shells are usually smooth and have a rounded apex, with a wide, open aperture.

The genus Involvarius was first described by the French naturalist Jean-Baptiste Lamarck in 1822. It is closely related to the genus Achatinella, and the two genera are often grouped together in the subfamily Achatinellinae. Involvarius species are hermaphroditic, meaning that each individual has both male and female reproductive organs. They reproduce sexually, with mating occurring in the water.

Involvarius species are generally considered to be of low conservation concern, as they are not threatened by any major factors. However, they may be affected by habitat loss and degradation, as well as by the introduction of invasive species. Further research is needed to fully understand the ecology and conservation status of Involvarius species.
