30 Examples of Mammals (With Pictures)

Animals in the class Mammalia, or mammals are arguably some of the more complex animals in the animal kingdom. Humans are mammals after all! Mammals are different from other types of animals and are warm blooded, fur/hair bearing, milk producing animals. In this article, we will cover several examples of mammals.

But first, let’s learn a little bit more about what it means to be a mammal.

What is a mammal?

Class: Mammalia

A mammal is a warm-blooded vertebrate that breathes air. Most mammals are terrestrial, often have fur or hair, and have more complex brains than other types of animals. Mammals nurse their babies and almost always give birth to live young, but there are some exceptions.

There are an estimated 130 billion mammals throughout the world today. Mammals and birds are the only warm blooded vertebrates on the planet. The largest mammal on earth, the blue whale, is on this list of examples of mammals.

30 examples of mammals

1. Dog

Scientific name: Canis lupus familiarlis

2. Raccoon

The Polar Bear is a large species of bear, well-known for surviving the harsh environment of the Arctic circle. Their white fur allows for them to blend in with the ice and snow in the tundra.
