Mammals

Definition of Mammals

Mammals are a class of vertebrates distinguished by their hair or fur, warm-blooded physiology, and the presence of mammary glands, which produce milk to nourish their young. Mammals include diverse species, from rodents and primates to whales and elephants.

Animals with Fur or Hair

Mammals are a group of warm-blooded animals that have fur or hair and feed their babies with milk. Humans, dogs, cats, whales, and elephants are all mammals. They live in many places, from oceans to forests to deserts.

What Makes Them Special?

• Fur or Hair: Helps keep them warm and protects their skin.
• Milk for Babies: Mammal mothers produce milk to feed their young.
• Warm-Blooded: Their bodies stay warm, no matter the outside temperature.
• Lungs for Breathing: Even aquatic mammals like dolphins breathe air.

Examples of Mammals

• Carnivores: Lions, wolves, and tigers that hunt for meat.
• Herbivores: Deer, cows, and giraffes that eat plants.
• Aquatic Mammals: Whales, dolphins, and seals that live in water.
• Humans: Yes, we’re mammals too!

Where Mammals Live

Mammals live almost everywhere on Earth:

• Forests: Bears, monkeys, and squirrels thrive among trees.
• Deserts: Camels survive in the hot, dry sands.
• Oceans: Whales and sea otters live and hunt in water.
• Cities: Rats, bats, and even pets like cats and dogs share spaces with humans.

Why Mammals Are Important

Mammals are vital for ecosystems:

• Pollination: Some mammals, like bats, help pollinate flowers.
• Seed Spreaders: Mammals like squirrels plant seeds by burying nuts.
• Balance Ecosystems: Predators keep prey populations under control.

Threats to Mammals

• Habitat Loss: Clearing forests or draining wetlands destroys homes for mammals.
• Hunting and Poaching: Animals like elephants are hunted for ivory, and tigers for their fur.
• Climate Change: Changing temperatures affect food and water sources.

Why Mammals Matter

Mammals are some of the most amazing animals on Earth. From tiny mice to giant whales, they show how life can thrive in all kinds of environments. By protecting mammals, we also protect the ecosystems they help keep healthy and balanced!
