Detailed explanation-1: -In strepsirrhines (i.e., lemurs and lorises), this bony enclosure takes the form of a postorbital bar only, while haplorhines (i.e., tarsiers, monkeys, apes, and humans) also possess a postorbital plate (Figure 3).
Detailed explanation-2: -The haplorrhine suborder, which includes tarsiers, monkeys, apes, and humans, has only two nocturnal members: the tarsier and the owl monkey, sometimes called the night monkey.
Detailed explanation-3: -Strepsirhines have longer snouts, smaller brains and a more highly developed sense of smell than haplorhines. Haplorhines have shorter faces, larger brains and a more highly developed sense of vision than Strepsirhines; their eyes face more forward than the eyes of strepsirhines.
