Why giraffe tongue purple

Their necks are 6 feet long on average, which is why they need powerful cardiovascular systems. But new research suggests perhaps giraffes do have a distinct sound: They hum.

Beyond the occasional snort or grunt, the researchers recorded humming sounds that the giraffes made only at night. The giraffe is the tallest land mammal alive, its long legs and neck contributing to its impressive stature. The French zoologist Jean-Baptiste Lamarck is usually credited as the first person to suggest that long necks have evolved in giraffes because they allow them to get to the parts other herbivores cannot reach. Giraffes have a tongue that is 46 centimetres long and can reach around the thorns.

Their thick, sticky saliva coats any thorns they might swallow. Both animals use their tongues, or their trunk, to grab food in the wild — like humans would use their hands.

Tiny bumps called papillae give the tongue its rough texture. Thousands of taste buds cover the surfaces of the papillae.

Taste buds are collections of nerve-like cells that connect to nerves running into the brain. National Geographic confirms that these gentle giants are the tallest land mammals in the world. Their necks are 6 feet long on average, which is why they need powerful cardiovascular systems. Why does a giraffe need such a long tongue?
