Question

Which suborder exhibits the following characteristics: Post orbital bar and partial plate, 3 premolars, continuous hairy upper lip and dry nose, grooming claws on digits 2 and 3, elongated tarsal bones, a dental formula of 2133/1123, carnivorous diet, eyes larger than brains, solitary behavior, and head rotation? A) Prosimii B) Anthropoidea C) Tarsiiformes D) Strepsirrhini

Answer 1

The suborder Tarsiiformes exhibits the described traits of a post orbital bar and partial plate, 3 premolars, a hairy upper lip and dry nose, grooming claws on digits 2 and 3, elongated tarsal bones, a 2133/1123 dental formula, carnivorous diet, large eyes, and solitary behavior.

Step-by-step explanation:

The suborder that displays the characteristics of a post-orbital bar and partial plate, 3 premolars, a continuous hairy upper lip and a dry nose, grooming claws on digits 2 and 3, elongated tarsal bones, a dental formula of 2133/1123, a carnivorous diet, eyes larger than their brains, and solitary behavior is C) Tarsiiformes.

This group is unique in the primate realm due to their variance of both prosimian and anthropoid traits. They are the smallest known primates, commonly nocturnal, and have extremely large eyes relative to their skull size. Unlike other primates, tarsiers have a diet predominantly of carnivorous nature, consuming chiefly flying insects and occasionally even small creatures such as bats and lizards.
