Animals say “hello” to each other

Animals say “hello” to each other

　How do you greet your friends? People from different cultures may have different answers: shaking hands, nodding, kissing... But do you know how animals “say hello” to each other?

　We know chimpanzees¹ are a lot like humans. Chimpanzees usually greet each other with a hand touch, a hug or sometimes a kiss.

　Giraffes seldom make loud sounds. Male giraffes often use their necks to greet each other. Their necks can reach up to two meters. When two giraffes meet, they may “shake” their necks and rub² them against each other. This is to feel how strong and tall the other is.

　Dolphins greet one another with whistles³. Every dolphin has a different whistle. It tells information about the dolphin, such as its age and health. Dolphins are very clever. They can copy new sound, and learn a new language.
