| description | Drilling predation plays an important role in the evolution and diversification of organisms,and is one of the most studied biotic interactions in fossil and modern records.Marks of drilling predation on mollusc shells are proof of food activity and the selectivepressure of one taxon on another. In this study, we explore drilling predation on preservedbivalve death assemblages (thanatocoenosis) at Playa Guardalavaca, Cuba. We characterizethe taxonomic composition, relative abundance and incidence of drilling. Furthermore,geometric morphometric tools were used to test whether there was a preference forany particular form of shell. Forty-eight species were identified, and a little less than half(21) showed drilling predation marks. The families with the highest species richness wereLucinidae and Tellinidae, with 11 species each. A total of 1,726 valves were quantified,estimating an abundance of 863 specimens. 190 valves showed drilling marks (22% of theabundance). The most abundant species were Lucina sp. (464 shells), Divalinga quadrisulcata(328), Americardia media (242), Ctena imbricatula (156), and Chione spp. (117).However, the most predated species were Epicodakia sp. (100%), Acorylus gouldii (56%),and Eurytellina sp. (44%). The highest predation rate occurs on small and medium-sizedvalves (≤ 7 mm); however, according to the Kolmogorov-Smirnov test, this result is onlystatistically significative in Lucina sp. (p < 0.001). The morphometric analysis showed predationpreferences for species with semi-circular rather than elliptical shells. These resultselucidate that drilling predation on bivalves is not only determined by the abundance ofprey, but also by their external morphology and size, suggesting highly specialised feedingbehaviour by predators. |

La depredación por perforación juega un importante papel en la evolución y diversificación de los organismos y es una de las interacciones bióticas más estudiadas en el registro fósil y actual. Las marcas de depredación por perforación en las conchas de los moluscos son evidencias y pruebas de la actividad alimentaria y la presión selectiva de un taxón sobre el otro. En este estudio, se explora la depredación por perforación en ensamblajes preservados de bivalvos muertos (tanatocenosis) en Playa Guardalavaca, Cuba. Se caracteriza la composición taxonómica, su abundancia relativa y la incidencia de perforaciones. Además, técnicas de morfometría geométrica fueron utilizadas para evaluar si existe preferencia por alguna forma particular de las conchas. Cuarenta y ocho especies fueron identificadas, y poco menos de la mitad (21) presentaron marcas de depredación por perforación. Las familias con mayor riqueza de especies fueron Lucinidae y Tellinidae con 11 cada una. Un total de 1 726 valvas fueron cuantificadas, estimando una abundancia de 863 ejemplares. De estas 190 valvas presentaron marcas de perforación (22% de la abundancia). Las especies más abundantes fueron Lucina sp. (464 conchas), Divalinga quadrisulcata (328), Americardia media (242), Ctena imbricatula (156) y Chione spp. (117). No obstante, las especies más depredadas fueron Epicodakia sp. (100%), Acorylus gouldii (56%) y Eurytellina sp. (44%). La mayor tasa de depredación se encontró en conchas pequeñas y medianas (≤ 7 mm); no obstante, acorde a la prueba de Kolmogorov-Smirnov, este resultado es estadísticamente significativo solo para Lucina sp. (p < 0.001). El análisis morfométrico mostró preferencias de depredación por especies con conchas semicirculares en lugar de las elípticas. Estos resultados evidencian que la depredación por perforación en bivalvos no está solo determinada por la abundancia de presas, sino también por su morfología externa y tamaño, sugiriendo comportamientos de alimentación altamente especializados de los depredadores.
