In this undated image released Thursday, March 12, 2009 by Prof. Nobuo Masataka of Kyoto University Primate Research Institute of Japan, a crab-eating macaque baby looks at its mother flossing to clean teeth by using human hairs in Lopburi, north of Bangkok,Thailand. A research team from Japan's Kyoto University, filming the activities of monkeys, found that some mother monkeys teach their infants how to clean their teeth by using human hairs. They appear to be flossing in the same manner as humans. Amongst a group of around 250 monkeys, about 100 have taken up the activity of flossing.
