Why do giraffes have a bump on their head?
When a giraffe is born, he has little bumps on his head that will eventually become his ossicones. These bumps are full of cartilage that isn’t attached to his skull. The bumps start to grow and ossify, beginning at the tip and hardening down toward the base of the horns.
What do ossicones do?
Function. Similar to species with horns or antlers, male giraffes use their ossicones as weapons during combat, where they use their heads as clubs: the ossicones add weight and concentrate the force of impact onto a small area, allowing it to deliver heavier blows with higher contact pressure.
