Differences in the shell shape of lymnaea peregra mueller gastropoda pulmonata from lotic and lentic habitats environmental or genetic variance


, : Differences in the shell shape of lymnaea peregra mueller gastropoda pulmonata from lotic and lentic habitats environmental or genetic variance. Journal of Molluscan Studies 54(2): 197-208

Lymnaea peregra from lotic habitats (running waters) had larger aperture-length/shell-length ratios than contemporaries from lentic sites (standing waters). This pattern was observed in field samples from two separate years (1985 and 1986). Laboratory culture experiments suggested that shell shape could be genetically determined in at least some popuations. We hypothesize that lotic snails possess bigger feet, and hence larger apertures than lentic individuals as an adaptation to withstand water current.
