The probability of a marine gastropod being infected by a trematode.
According to that hypothesis, proto-digeneans possessing a typical turbellaria-like structure adopted commensalism before becoming tissue parasites in gastropods.
In an extreme drought, activity of terrestrial gastropods undoubtedly is reduced and mortality increased.
Despite the clear ecological importance of terrestrial gastropods, little is known about the ecology of most species.
Thin-shelled bivalves, gastropods, crinoids and entomozoaceans dominate the fossil content.
In coastal ecosystems the first intermediate hosts of digenetic trematodes are mostly littoral gastropod molluscs.
One metre further above, the first marine gastropods appear within carbonaceous mudstones.
