Greater spot-nosed monkey

Not applicable as a mythological origin: the provided sources treat the greater spot-nosed monkey as a biological species described by taxonomic and natural-history literature rather than as a figure in myth or cosmology. Its 'origin' in the available material is the standard biological account of a West African guenon species discussed in zoological and documentary sources.

The species is characterized by a prominent white nose, which gives rise to its common names. It is one of the smaller Old World monkeys (a guenon); one source reports total length ranges and weight approximations (length roughly in the range reported as 43–70 cm and weight approximately 4–6.6 kg in the cited animalia.bio entry). The available descriptions emphasize the white-nosed facial marking and the small, arboreal body plan typical of guenons; other specific color-pattern details are not provided in the cited excerpts.

Behavioural descriptions in the sources emphasize social group structure, arboreal habits, and vocal communication. Groups are typically composed of a single adult male with multiple adult females and their dependent offspring; the species is arboreal and often associates with other monkey species. Males produce at least three call types labeled 'booms', 'pyows', and 'hacks', and individuals combine calls into sequences whose meanings can differ from the component calls—alarm-call acoustics vary with predator type and sequences can convey compound information. Some sources note susceptibility to malaria infection in a research context.
