Chilina Fasciata

''Chilina'' is a genus of air-breathing freshwater snails, aquatic pulmonate gastropod mollusks in the superfamily Chilinoidea.

''Chilina'' is the only genus in the family Chilinidae.

Distribution

Chilinidae occupies the temperate and cold zones of South America from the Tropic of Capricorn to Cape Horn and Falkland Islands.Brown D. S. & Pullan N. B. (1987).

Ecology

Within their area, the Chilinidae are abundant snails in all suitable stations, as Physidae are in North America. They swarm in springs, small streams, lakes, and in some places the margins of rivers. They are most abundant southward, becoming rarer and local toward the northern borders of their range.

''Chilina gibbosa'' and ''Chilina fluminea'' are medically important, because they transfer parasites causing dermatitis.
