Polygyra septemvolva, common name the Florida flatcoil, is a species of air-breathing land snail, a terrestrial gastropod mollusc in the family Polygyridae. ^[1]

Description

The shells of Polygyra septemvolva are known to show a high degree of variance in size within populations (6.6 - 14.8 mm). They have been proposed as a suitable model organism due to the ease of culturing and abundant reproduction in a suitable habitat. ^[2]
