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 selective pressure of one taxon on another. In this study, we explore drilling predation on pr...

... was conducted at Playa Guardalavaca, Banes Municipality, Holguín Province (Fig. 1). The samples were taken at a point where we found a concentration of valves (21°07'17.2''N; 75°50'22.9''W). This locality is a beach with biogenic white sands of about 800 m long, and is an important tourist destination with several hotels. Ecologically, it is a reef lagoon surrounded by coral promontories, with a sandy bottom covered ...

... These authors observed a higher predation rate on bivalves and noted that predation appeared to be non-elective and was determined by prey abundance. Recently, Diez et al. (2023) investigated this phenomenon on bivalve shell deposits and found that the predation rate was also related to the size and external morphology of prey. Moreover, drilling predation has been studied in the Cuban fossil record of serpulid polychaetes (Villegas-Martín et al., 2016), and drillholes were attributed to naticid gastropods. ...

... This argument is further supported by the high total predation rate (24.5%), which reaches even higher values for particular species. Our results for the study locality in Guardalavaca support the notion that predation rate on gastropods is similar to the situation in bivalves (22%; Diez et al., 2023). In other published studies, this parameter varies between 7% and 37% (Pruss et al., 2011), whereas in northern of Cuba, the recorded predation rates range from 19% to 29% (Gordillo et al., 2019). ...
