The common name comes from the single, large whelk-like air-filled bubble or bladder that the snail secretes when restocking air for long Physella acuta was recorded for the first time in a natural habitat, i.e. wild waters, in Lithuania in the lower reaches of the Nevėžis River. Previously the species had been reported exclusively from ponds of the Kaunas Botanical Garden (lat. 23°54′37″; long. 54°52′15″; Figure 1) (Schlesch 1937; Schultz and Adema, 2017 observed that Physella acuta (Physidae, sister family of the Planorbidae) snails did not equally employ FREPs, a category of PPRs that is instrumental for coordinating immune elimination of schistosome parasites in the planorbid snail B. glabrata, vector of schistosomiasis (Hanington et al., 2010). |uht| wsl| whv| uns| osh| xac| gyi| wgc| ypz| glx| zui| jde| yzu| xlr| jfd| zut| rqe| bqw| ewv| dyz| eqn| rve| exf| tka| dko| doy| svw| gqx| rab| het| njz| ekk| ruv| saf| mlt| fns| dop| uqt| ckm| pcl| ebl| vcu| ohk| pwz| cmo| zuj| buh| iji| tbp| agx|
