Mammals

Mammals are a diverse group of animals that share several defining characteristics. They are warm-blooded, meaning that they can maintain a consistent body temperature regardless of their environment. Mammals also have hair or fur, which helps them stay warm and protects their skin. They give birth to live young and nurse them with milk produced by mammary glands. Mammals are found in nearly every habitat on Earth, from oceans to deserts to rainforests. Some well-known mammals include humans, dogs, cats, cows, elephants, and whales. Mammals play a crucial role in ecosystems as both predators and prey, and many are important for their economic and cultural value to humans. They are also the subject of scientific research, as scientists seek to understand the diversity and evolution of mammalian species, as well as their behaviors, physiology, and conservation needs.
