Giraffes are known for a few key features: their long necks, beautiful camouflage and the dark tongue they use to strip leaves off branches. Steve Gerkin, interpretive programs manager at the North Carolina Zoo, visits the show to tell us why we think their tongues are that shade. Hint: humans share this trait with giraffes!
