Giraffe
The world's tallest mammal, native to the African savanna.
Adaptations: A very long neck allows it to browse on leaves high up on acacia trees, a food source other animals can't reach.
💡 Fun Facts
- Neck: A giraffe has the same number of neck bones as a human—just seven! Each vertebra, however, is extremely long, measuring up to 25 cm (10 inches).
- Tongue: To eat from thorny acacia trees, a giraffe uses its tough, 45 cm (18-inch) long prehensile tongue to delicately strip the leaves from between the spikes.
- Heart: To pump blood all the way up its long neck to its brain, a giraffe has a massive heart that can be 60 cm (2 feet) long and weigh over 11 kg (25 lbs).
