Mammalia
Mammals are a diverse group of warm-blooded animals known for their unique characteristics, such as having hair or fur on their bodies and producing milk to feed their young. They range from tiny creatures like mice and bats to some of the largest animals on Earth, like elephants and whales. Mammals live in various habitats, from dense forests and vast oceans to arid deserts and snowy mountain peaks.
