Giraffes' Spots for Camouflage and Cooling
Giraffes have spots that serve as thermal windows, allowing them to cool down by releasing heat through these darker patches. The spots help young giraffes stay safe and regulate their body temperature. The darker spots act as thermal windows where heat escapes, assisting in cooling. These spots are significantly warmer than other parts of the giraffe's body.
