Catarrhine monkeys live in social groups, while Platyrrhine monkeys are solitary

Platyrrhine monkeys have nasal openings facing outwards, while Catarrhine monkeys have nasal opening facing downwards

Platyrrhine monkeys are mostly frugivore, while Catarrhine monkeys are herbivore

Platyrrhine monkeys have prehensile tails, while Catarrhine monkeys do not

Solution

Answer:

Platyrrhine monkeys have nasal openings facing outwards, while Catarrhine monkeys have nasal opening facing downwards

Platyrrhine monkeys have prehensile tails, while Catarrhine monkeys do not.

Explanation:

The most obvious difference is the shape of the nose: platyrrhine means flat-nosed, while catarrhine means hook-nosed. In platyrrhines, the nostrils are farther apart and they point outward, while in the catarrhines, they\'re closer together and they point down.

Most New World monkeys have prehensile tails while Old World monkeys have non-prehensile tails or no visible tail at all.
