The largest value of this character typical for amla-like life form. The dominance of one life form is a result of its adaptation to life in places with wave activity and for water respiration. Large relative species richness of subgenuses Lymnaea and Peregriana is a sequence of ampla-like life form dominance, wuch consist from these subgenuses.
