  • Lydia Luncz at the University of Oxford, wanted to investigate the impact of the monkeys' shellfish snacking on the prey themselves with stone tools. Stone tools open up an opportunity for foods, where macaques otherwise wouldn't even be able to harvest, says Luncz. Her team followed 18 macaques on their daily foraging routes along the shores of Koram and NomSao, two neighbouring islands off eastern Thailand, recording their tool selection and use, and found out that multiple prey species were less abundant on Koram than NomSao, with four times as many tropical periwinkles on NomSao as on Koram.
