Differences between Platyrrhines and Catarrhines The most obvious difference is the shape of the nose: platyrrhine means flat-nosed, whilecatarrhine 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.
Then, what is a Platyrrhine nose?
The platyrrhine nose (on the left below) is relatively flat with somewhat sideways projecting nostrils separated by a wide septum. In contrast, the catarrhine. nose (on the right below) has more downward projecting nostrils separated by a small septum.
