In organisms encountering predictable environments, fixed development is expected, whereas in organisms that cannot predict their future environment, phenotypic plasticity would be optimal to increase local adaptation. L. littorea is oviparous, reproducing annually with internal fertilization of egg capsules that are then shed directly into the sea, leading to a planktotrophic larval development time of four to seven weeks.

However, some tiny tropical species live for less than 1 year and their life cycle takes only about 3 months (Hopkin and Read, 1992). 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.
