Explanation:

1. A prehensile tail is the tail of an animal that can be used to grasp or hold objects. Fully prehensile tails can be used to manipulate objects, finding and eating foods in trees. The tails of Old World monkeys are not prehensile.

2. Old World monkeys are partially omnivorous. They primarily eat fruits while consuming other food items available ranging from leaves, insects, bulbs, flowers, snails and even small vertebrates.

3. The dental formula is 2.1.2.3. We humans share the same dental formula with them.

4. Due to long period of sitting or sleeping on rough branches and rocks, Old World monkeys have ischial callosites or hairless callous pads on thier rumps.
