Giraffes are amazing animals. They are the tallest land animals on earth. An adult giraffe can grow up to 5.5 meters tall. Their long necks and legs help them reach leaves high on trees. Giraffes live in Africa’s savannas and open woodlands. They eat leaves from acacia trees. A giraffe can eat 34 kilograms of leaves daily. Their tongues are dark blue and up to 50 centimeters long. This helps them pull leaves from thorny trees safely.
Each giraffe has unique brown patches（斑点）on its coat. These patterns are like human fingerprints. Scientists think the patterns help giraffes hide from lions and other predators.
Giraffes live in groups called “towers”. Female giraffes and their babies stay together. Male giraffes sometimes fight by hitting each other with their necks. This is called “necking”.
Sadly, giraffes are in danger. Their numbers dropped by 40% in 30 years. People cut down trees and hunt them. Protecting giraffes is important.
