Mammals are a diverse group of warm-blooded vertebrates that typically have hair or fur covering their bodies, give birth to live young, and nurse their offspring with milk produced by mammary glands. They can be found in a wide range of habitats, from the depths of the ocean to the highest mountains. Mammals play a vital role in ecosystems as predators, prey, seed dispersers, and more. Research in this area can focus on various aspects of mammalian biology, behavior, ecology, evolution, conservation, and the impacts of human activities on mammal populations. Studies may also investigate the adaptations that enable mammals to thrive in diverse environments, their social structures, communication strategies, and interactions with other species in their ecosystems.
