## 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.
