AbstractA large sample rich in empty Bithynia tentaculata
(Linnaeus, 1758) was collected in a drift-line along Lake IJssel,
The Netherlands. Of 400 adult Bithynia shells 62 (15.5%)
showed repair of a damaged outer lip, most probably due to
failed attacks by predators. The roach Rutilus rutilus (Linnaeus,
1758) was probably its main shell-crushing predator here.
However, repair after physical damage by waves breaking on
the stones of the dike cannot be excluded completely.
