Lymnaea acuminata

[1] This snail lives in water bodies such as lakes, streams, and wetlands with thick vegetation.

[2] It is also an intermediate host for the liver flukes Fasciola gigantica and F. hepatica, which cause the infectious disease fasciolosis in humans and other mammals.

For example, mystery snails are sexually dimorphic, meaning they have separate males and females that must pair up to reproduce.

Females lay their eggs in clumps on firm, clean surfaces like rocks, logs, or aquatic vegetation.

Freshwater snails reproduce by laying eggs in clumps, which are usually attached to plants or other surfaces in the water.
