Final answer:
Lemurs, lorises, and tarsiers are part of the Strepsirrhini primate suborder, which is characterized by unique anatomical features that distinguish them from the Haplorhini suborder.
Step-by-step explanation:
Based on primate taxonomy, lemurs, lorises, and tarsiers are part of the Strepsirrhini primate suborder. Strepsirrhini primates, also known as strepsirrhines, have several distinguishing anatomical features such as a grooming claw on the second toe and lower incisors that form a toothcomb used for grooming. Additionally, there are seven families of living strepsirrhines, predominantly found in the Old World, which includes Africa, Asia, and Europe. In contrast, the haplorrhines or Anthropoids, which include humans, apes, and all monkeys, possess different physical and behavioral traits compared to the Strepsirrhini suborder.
