Simiansmonkeys

Simiansmonkeys is not a recognized term in formal primatology. It appears to be a nonstandard or conflated label that mixes the words simians and monkeys, and it may be used informally or by mistake in non-specialist contexts.

In scientific usage, simians refer to the infraorder Simiiformes, which includes all higher primates—monkeys, apes, and humans. Tarsiers are not simians; they belong to a different infraorder, Haplorhini. Within Simiiformes, the group commonly called monkeys consists of two parvorders: Platyrrhini (New World monkeys) and Catarrhini (Old World monkeys). Apes are not monkeys; they are part of the superfamily Hominoidea within Catarrhini and include gibbons (lesser apes) and the great apes (orangutans, gorillas, chimpanzees) as well as humans.

Examples of monkeys include capuchins and howler monkeys (New World), baboons and macaques (Old World). Apes include chimpanzees, gorillas, orangutans, and humans. The broader simian group covers a wide range of body sizes, social systems, and habitats, from tropical forests to savannas. Most simians are diurnal and arboreal, though there is substantial variation in diet, locomotion, and social structure.

Conservation concerns affect many simians and monkeys, with habitat loss, hunting, and disease contributing to declines in several species. The term “simiansmonkeys” is generally avoided in scholarly works in favor of precise classifications like Simiiformes, Platyrrhini, Catarrhini, or Hominoidea.
