They are parasitic on a variety of molluscs, crustaceans, birds, and mammals, some species having complex life cycles involving more than one host.. For example, Microphallus piriformes parasitizes the rough periwinkle (Littorina saxatilis); when these are eaten by herring gulls it infects the bird and lays its eggs in the bird's feces to infect new periwinkles. Breeding can occur throughout the year. Merseyside BioBank., 2018. Miscellaneous records held on the Cofnod database.

(previous page) () L. saxatilis, which lives high up on rocks and is often out of water for long periods of time, holds its embryos in a brood sac until the young are fully developed, at which time they emerge as tiny crawling replicas of the adult.

Littorina saxatilis, common name the rough periwinkle, is a species of small sea snail, a marine gastropod mollusc in the family Littorinidae, the winkles or periwinkles. The parasites are Microphallus similis (Jaegerskioeld, 1900) (=C. The planktonic larval stage is long (up to 6 weeks) although larvae do tend to remain in waters close to the shore.
