We conducted a laboratory study to determine drillhole siteselectivity  patterns in the predatory behavior of Notocochlis unifasciata  (Lamarck, 1822), which is a common naticid gastropod  on the eastern Pacific coast of Central America, preying on two  infaunal venerid bivalves – the thin-shelled and weakly ornamented  Leukoma grata (Say, 1831) and the thick-shelled and  strongly ornamented Iliochione subrugosa (Wood, 1828). Spatial  patterns of drillhole distribution indicate strong preferences for  drilling the umbonal region and the ventral edge of the shell, with  the proportion of edge- to wall-drilling attacks increasing in  thicker, strongly ornamented prey that were larger than their  predator’s own size. Drilling patterns from museum and beach...
