Bamboo bear

Iconic black-and-white bear of the mountain bamboo forests of central China, giant pandas can weigh up to 125 kg and spend up to 14 hours daily consuming bamboo, which comprises 99% of their diet despite belonging to the order Carnivora. Solitary and elusive, they have a pseudo-thumb for gripping bamboo stems. Downgraded from Endangered to Vulnerable in 2016 following successful conservation and breeding programs.

Common Ostrich

The world's largest and heaviest living bird, common ostriches stand up to 2.8 meters tall and weigh 156 kg, inhabiting savannas and semi-arid plains of Africa. Flightless, they compensate with powerful long legs capable of delivering lethal kicks and sustaining running speeds of 70 km/h — the fastest of any bird. Their large eyes are the biggest of any land vertebrate. Ostriches lay the largest eggs of any living bird.
