Giraffes are the tallest living land animals on Earth.

They are also the largest ruminants, which are animals that chew their food in a special way. These large mammals belong to the family Giraffidae. Their closest living relative is the okapi. Most people think of giraffes as one single species. However, recent research suggests they might actually be four different species. These species can be told apart by their unique fur patterns.

Living giraffes have very specific ways of life. They use their long necks to reach leaves, fruits, and flowers. They especially love to eat from acacia trees. This helps them reach food that other ground animals cannot reach.

Giraffes live in different types of groups. Some live in herds of related females and their babies. Other males live together in groups called bachelor herds. Males sometimes use their necks as weapons in fights. This behavior is called "necking," and it helps them decide who is the leader.

Giraffes have a very long history on our planet. Scientists have found fossils of six extinct giraffe species. One early relative was called Canthumeryx, which lived in Libya. Another animal called Giraffokeryx lived on the Indian subcontinent. A fossil named Samotherium is very important to researchers. Its neck was halfway between an okapi and a modern giraffe. Later, an animal called Bohlinia lived in Europe and China. This animal looked very much like the giraffes we see today.

Today, giraffes live in many parts of Africa. Their range goes from Chad in the north to South Africa in the south. They can be found from Niger in the west to Somalia in the east. In 2016, there were about 97,500 giraffes living in the wild. Some animals like lions, leopards, and hyenas may hunt them. Many giraffes also live in zoos around the world. In 2010, more than 1,600 giraffes were kept in zoos.

Learning about giraffes helps us understand how life changes. Long ago, forests turned into open savannahs. This change likely helped the giraffe's neck grow longer over time. Some scientists think eating certain plants may have even helped them evolve. We can see how they are related to other animals through their genes. For example, the okapi and the giraffe share many similar proteins. This shows us how all living things are connected through history.
