Background: Lymnaea stagnalis (L., 1758), the great pond snail, is among the most common and ubiquitous species of aquatic pulmonate gastropods of Palearctic. californica) even using a low stringency e-value cutoff at 0.01. The annotated sequences contribute 12% of the predicted transcriptome size of 20,000. The pulmonate gastropod Lymnaea stagnalis (Linnaeus, 1758) was once a much used model for understanding both molluscan development in general [26] and develop-ment of the shell in particular[27].

Sex allocation proxies of Lymnaea stagnalis of different ages and sizes. Superfamily … The large size, tall spire and swollen last whorl make this species one of the most distinctive lymnaeids. The common mud snail has typical triangular antennae that widen towards the base. Nonetheless, copulating indi- viduals of L. stagnalis can only perform one sexual role at a time: one snail adopts the male role (sperm donor) while the other adopts the female role (sperm recipient). Surprisingly, approximately 37% of the L. JoVE publishes peer-reviewed scientific video protocols to accelerate biological, medical, chemical and physical research. A closed symbol indicates a small individual and an open symbol a large one. The long, pointed, slightly bulbous, light brown to dark brown shell of the Great Pond Snail, Lymnaea stagnalis, from Central Europe is up to 6 cm long in the garden pond, in the aquarium the animals usually remain significantly smaller.
