Mammalogy is the scientific study of mammals, a diverse group of warm-blooded animals characterized by the presence of hair or fur and mammary glands that produce milk for their young. This field encompasses the classification, behavior, ecology, and evolution of mammals, which include species ranging from tiny shrews to large whales. Mammalogists, the scientists who specialize in this area, often conduct research in various habitats to understand how mammals interact with their environment and each other. They may study the anatomy of mammals, their reproductive habits, and their roles in ecosystems, contributing valuable knowledge to conservation efforts and biodiversity preservation.
