Predatory shell-drilling by the land snail Haplotrema concavum (Say, 1821) (Haplotrematidae)
Abstract
The predatory land snail Haplotrema concavum (Say, 1821) consumed twelve species of land snails during feeding trials. Haplotrema concavum was able to force its head into the shells of prey species with relatively large apertures and body whorls (Anguispira species), but drilled the shells of smaller snails to gain access into the shell. The holes drilled by H. concavum in the shells of its prey were always through the lower periphery of the body whorl at a location about a quarter of a whorl in front of the aperture. A hole at this location provided H. concavum direct access to the body of the snail inside.
