Resumo: | The predatory behaviour of Poiretia snails is studied. One  aspect of this behaviour is the ability to make holes in the  shells of prey snails. The radula and the histology of the  mucous glands support the assumption that Poiretia secretes  acidic mucus to produce these holes. Observation of a  Poiretia compressa (Mousson, 1859) specimen yielded the  insight that its activities relied on the availability of moisture  and not on light conditions. It preyed on a wide range of snail  species, but only produced holes in shells when the aperture  was blocked. It usually stabbed its prey with a quick motion  of the radula. The time it spent feeding on a prey specimen is  most likely correlated to prey size.
