Viewers were left in stitches as a lion-tailed macaque repeatedly slapped a giant squirrel in a fight over an enormous jackfruit on last night's episode of BBC1's Primates. The 'marvellous' moment happened during a segment about the macaques living in the Western Ghats mountain range in India. It showed how lion-tailed macaques took advantage of the Malabar giant squirrel's sense of smell to locate ripe jackfruit and steal it from them. Using a surprisingly simple technique, the macaque simply batted the squirrel repeatedly on the nose to keep it away from the food.
