Catarrhines have flat fingernails and those that have tails, do not use them for gripping. Other simians use their tails for gripping branches of trees or alike.

Catarrhines have pointed noses.

The division between catarrhini and platyrrhini developed during a period between 40 and 25 million years ago.

Catarrhines are split into two superfamilies. These superfamilies are cercopithecoidea and hominoidea.

Cercopithecoidea are more commonly known as old world monkeys.

Hominoidea are otherwise known as apes. Strictly speaking, apes are agile tree climbers and are mainly omnivorous.

Some animals which are called apes are not actually apes in the true sense of the word, in respect of the parvorder of catarrhini.
