Macaques are a type of Old World monkey that are native to Asia and Africa. They are known for their distinctive appearance, with their short tails and long, sharp canine teeth. Macaques are highly social animals, living in large groups known as troops. They are omnivores, feeding on a variety of foods including fruits, leaves, insects, and small animals. In the field of research, macaques are commonly used as animal models for studying a wide range of topics including behavior, cognition, genetics, and neuroscience. They have been particularly valuable in research related to infectious diseases, such as HIV/AIDS and malaria, as their immune system closely resembles that of humans. Macaques have also been used in studies of social behavior, olfaction, and communication. Overall, macaques are a versatile and valuable research model for studying a variety of scientific questions and have contributed significantly to our understanding of biology and medicine.
