I've always loved giraffes and purple is one of my favourite colours.
From: Nice News
Giraffes have purple tongues.
In addition to their spots and long necks, giraffes have another distinguishing feature: Their tongues are often dark purple. Whereas most animals have fully pink tongues, a giraffe’s is infused with melanin that makes it darker; sometimes it’s even blue or black rather than purple, although the base and back are indeed pink. While it hasn’t been proven definitively, there’s a widely accepted theory that the melanin provides ultraviolet protection, preventing giraffe tongues from getting sunburned while the animals feed on tall trees. Giraffe tongues are also long (up to 21 inches) and covered in thick bumps known as papillae, which help protect them from the spiky defensive thorns of the animal’s favorite snack: acacia trees.
