Photo of the day (83): Pleurodonte isabella

Pleurodonte isabella (Férussac, 1822) is a neotropical land snail from the family Pleurodontidae. It is also known as “Pleurodonte sp. Barbados” among snail pet keepers. It is variable in color: it can be brown, yellow, orange, blue or purple.

Pleurodonte isabellaIt is endemic to Barbados. It is widespread and abundant there. It inhabits natural environment as well as disturbed habitats. There is wet season and dry season in Barbados. Temperature ranges from 21 to 31 °C. But snails keepers recommend to keep this species in temperature 22-24 °C and in humidity 70-80 %.

It is herbivorous species. It is nuisance occasionally when it eats gingers Zingiber sp. and heliconias Heliconia sp. flowers. It was also reported as a pest on Citrus.

Various right side views:

This flower occurs in the same areas as Pleurodonte isabella, but it has molluscicidal activity. Various extracts of Canna indica kills freshwater molluscs, because it is nerve agent to them. I found that, that Pleurodonte isabella avoid eating this plant in terrarium. So it seems that they are clever enough to not poison itself.

The width of the shell of this specimen is 18 mm, the height of the shell is 13 mm.

Umbilical view:
Pleurodonte isabellaI did not identify this species by myself. I was able to get some information about ecology of Pleurodonte isabella, but I failed to get information about proper identification of the species. I am glad that an expert in Neotropical malacolofauna helped me in identification/verification.
