Detailed explanation-1: -Strepsirrhines are the only primates that rely mostly on smell for hunting and social interactions. They have large eyes and ears. Strepsirrhines live in tropical Africa and Asia. Most are found only in Madagascar and nearby islands.

Detailed explanation-2: -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.

Detailed explanation-3: -All primates rely more on sight than any other sense. As a result, primate skulls are shaped in a way to maximize their vision.

Detailed explanation-4: -Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys, including apes and humans).
