Did you know that giraffes can bleat, meow, cough, moo, roar, snort, whistle, grunt, and snore? But the most interesting thing is that they are very sociable animals. And they “talk” to each other with the help of infrasound, which cannot be heard by the human ear.

Researchers even managed to decode some of the sounds. For example, when a male coughs, they show their affection to a female. And if they moan or grumble, they show that they’re in conflict with other males. If a female hisses, she’s scolding or teaching a young giraffe.
