Sky-High Sleepers: Giraffes only need about 30 minutes of sleep a day! Purple Tongues: Their 45cm-long tongues are dark to avoid sunburn. Neck Butting: Males fight by swinging their long necks in “necking” battles. Fast Sprinters: Despite their size, they can run up to 60 km/h. Unique Prints: No two giraffes have the same spot pattern—like fingerprints.   Share this post, learn more about conservation partners on our charity page, or shop our bracelets to help fund on-the-ground projects.
