Mammalogy is the scientific study of mammals, a diverse group of warm-blooded vertebrates 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 bats 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. Their work contributes to conservation efforts, helping to protect endangered species and maintain biodiversity within ecosystems.
