Why do giraffes have patches on their skin?

Giraffes have patches on their skin that serve multiple purposes. These patches help regulate body temperature by housing a network of blood vessels that dissipate heat. They also provide camouflage, breaking up the giraffe’s outline and helping it blend into the dappled light of savannah trees. Additionally, the patterns are unique to each giraffe, much like fingerprints, and may play a role in social recognition. The combination of function and individuality makes these patches a vital feature for survival.
