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 Dermatitis is a term used for different types of skin inflammation, typically characterized by itchiness, redness and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened ...
