Abstract:
At both beaches, valves belonging to seven genera of bivalves were the most abundant shells counted, but abundances do not appear to be linked to drilling intensity. For instance, at Haitian Boat Beach, Glycymeris accounts for 14% of total shells counted and only 18% of Glycymeris valves are drilled. At Sandy Point Beach, Glycymeris accounts for 7% of shells counted, yet 44% of these shells are drilled. Interestingly, gastropods, which make up a small proportion of the population at both beaches, exhibit high drilling frequencies. Based on the shape of the drill holes, naticid gastropods are the likely predators. Future work will focus on the possible environmental and/or ecological differences between the two beaches that may provide insights into what controls drilling frequencies in modern carbonate settings.
