Old World Monkeys are the frugivores of the month
"Of the known 634 primate species in the world 48 percent are currently threatened with extinction, making mankind's closes relatives one of the most endangered animal groups in the world." More at Mongabay.com

The Old World monkeys
are a group of primates, falling in the superfamily Cercopithecoidea in the clade Catarrhini. The family Cercopithecidae
includes 18 genera and 81 species. (see below) These monkeys are widely distributed in the Old World from southern Europe (Gibraltar) into NW Africa; throughout Africa south of the Sahara; and through central and SE Asia, including southern China and most of Japan. The Old World monkeys are inhabiting a range of environments from tropical rain forest to savanna, scrubland, and mountainous terrain. Old World monkeys and baboons, includes macaques, rhesus, mangabeys, mandrills, guenons, patas monkeys, langurs, proboscis monkeys, colubus, and many others.

Old World monkeys are medium to large in size, and range from arboreal forms, such as the colobus monkeys, to fully terrestrial forms, such as the baboons. The smallest is the Talapoin, with a head and body 34-37 cm in length, and weighing between 0.7 and 1.3 kilograms, while the largest is the male Mandrill (the females of the species being significantly smaller), at around 70 cm in length, and weighing up to 50 kilograms. The cercopithecines are omnivorous, have cheek pouches, and simple stomachs. Many authors are studying frugivory among Old World Moneys and their crucial role as seed dispersers.

Most Old World monkeys are at least partially omnivorous, but all prefer plant matter, which forms the bulk of their diet. Leaf monkeys are the most vegetarian, subsisting primarily on leaves, and eating only a small number of insects, while the other species are highly opportunistic, primarily eating fruit, but also consuming almost any food items available, such as flowers, leaves, bulbs and rhizomes, insects, snails, and even small vertebrates.
