          Abstract

          Abstract In this study investigates the predatory activity on a Holocene gastropod from the Argentinean Malacological Province. Buccinanops deformis (King, 1832), endemic in the southern hemisphere, is a typical taxon of cold-waters and high latitudes. We observed direct evidence of durophagy as lethal and sublethal damage. Sublethal damage was studied using traces of repaired shell as an indicator of activity by durophagous predators. Three parameters were used to evaluate durophagous predation: frequency of predation, repair scar frequency and prey effectiveness. A predatory-prey interaction was identified between Danielethus crenulatus (A. Milne-Edwards, 1879) and B. deformis during the Holocene on the Argentinean littoral coast. The low value observed for shell repair frequency (0.06), the low frequency of predation (0.16), and the intermediate value for prey effectiveness (0.37) may be interpreted because of a low but effective predatory activity.

          Resumen En este estudio se investiga la actividad depredadora sobre una especie de gasterópodo del Holoceno de la Provincia Malacológica Argentina. Buccinanops deformis (King, 1832) es una especie que habita en aguas frías en latitudes altas, endémica del Hemisferio Sur. Este estudio está basado en la evidencia directa de la durofagia tanto en daño letal como subletal. El daño subletal fue inferido utilizando la evidencia de los exoesqueletos reparadas como un proxy de este tipo de actividad. Se emplearon tres parámetros para la evaluación de la depredación durófaga: la frecuencia de depredación, la frecuencia de cicatrices reparadas y la efectividad de la presa. Se identificó la interacción depredador-presa entre el cangrejo Danielethus crenulatus (A. Milne-Edwards, 1879) y B. deformis durante el Holoceno en las costas litorales argentinas. El bajo grado de la frecuencia de depredación (0.16) y reparación del exoesqueleto (0.06) y el valor medio de la efectividad de la presa (0.37) se interpretaron como resultado de una baja pero efectiva actividad depredadora.

          The Mesozoic marine revolution: evidence from snails, predators and grazers

          Tertiary and Recent marine gastropods include in their ranks a complement of mechanically sturdy forms unknown in earlier epochs. Open coiling, planispiral coiling, and umbilici detract from shell sturdiness, and were commoner among Paleozoic and Early Mesozoic gastropods than among younger forms. Strong external sculpture, narrow elongate apertures, and apertural dentition promote resistance to crushing predation and are primarily associated with post-Jurassic mesogastropods, neogastropods, and neritaceans. The ability to remodel the interior of the shell, developed primarily in gastropods with a non-nacreous shell structure, has contributed greatly to the acquisition of these antipredatory features.
