In Kentucky, it has been documented in the Kentucky River drainage (Lake Arlington) (Branson and Batch, 1981). The upper whorls are pointed, the last whorl is suddenly inflated, so that its diameter is more than a continuous increase of that of the upper whorls. In Indiana, Pyron et al. 2015. It is listed as secure in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. This is believed to be the first published record of the occurrence in Canada of this schistosome dermatitis-producing parasite. The size to which a specimen will grow is dependent upon the volume of water in the pond; individuals grow larger in big ponds.

Studies using the central nervous system of Lymnaea stagnalis as a model organism have also identified novel cellular and molecular mechanisms in neuronal regeneration, synapse formation, synaptic plasticity, learning and memory formation, the neurobiology of development and aging, the modulatory role of neuropeptides, and adaptive responses to hypoxic stress.[9].
