Mammals are a diverse group of animals that are found all over the world. In this lesson, we will explore the basic concepts of mammals, their characteristics, their diversity, and their importance.
Characteristics of Mammals
Mammals share several key characteristics that differentiate them from other groups of animals:
Mammary Glands – All female mammals produce milk to feed their young.
Hair or Fur – Mammals have hair or fur that covers their bodies and provides insulation.
Three Middle Ear Bones – Mammals have three middle ear bones, which enable them to hear a wider range of sounds.
Warm-Blooded – Mammals are warm-blooded, which means they can maintain a constant body temperature even in different environments.

Importance of Mammals
Mammals play a vital role in many ecosystems and have a significant impact on the world around us. They are important for:
Pollination – Some species of mammals, such as bats, are important pollinators for many plants.
Seed Dispersal – Many mammals, such as rodents and primates, help to disperse seeds across different habitats.
