Answer 2

Most mammals have hair or fur and four legs. Some mammals, like whales, have evolved to live in water, but they don't have gills. Instead, they have lungs, like land mammals, and they breathe air. Additionally, all mammals are warm-blooded, which means they can regulate their body temperature internally, and they feed their babies with milk produced by mammary glands.
