Despite the camouflage spots in their fur giraffes do not always remain undetected by predators. But they know to defend themselves and can kick really hard with their front hooves. They mainly do this if they want to protect their young because the adult animals are normally rarely attacked. 

Anyone who has the opportunity to look at giraffes from close up can easily distinguish the females from the males. They are somewhat smaller and have thin horns with a small tuft of fur on top. Giraffe bulls in contrast have thick horns with no fur on top.
