What species are included in Group 3 for nonhuman primate cage size requirements?

The inclusion of macaques and African species in Group 3 for nonhuman primate cage size requirements aligns with the Animal Welfare Act's guidelines, which specify different cage size standards based on the size and needs of the species. Macaques, being larger primates, have specific spatial requirements to accommodate their physical and behavioral needs. Additionally, African species, including others that fall under the same size class, also require similar cage dimensions to promote their welfare. This classification is essential not only for providing adequate living conditions but also for ensuring the wellbeing of the animals by allowing them enough space to engage in natural behaviors, reduce stress, and maintain their health.

The other options do not align with the established groupings according to the Animal Welfare Act. Infants, capuchins, and wire-haired species do not fall under the same category in terms of size requirements, which is why they are not included in Group 3. The focus on larger-bodied primates like macaques and various African species highlights a clear understanding of species-related needs within the context of animal care regulations.
