Despite the giant panda’s diet is over 99% bamboo, its taxonomic classification as a carnivoran, because it still has the digestive system of a carnivore, as well as carnivore-specific genes, and thus derives little energy and little protein from consumption of bamboo. Its large size and round face, are adaptations to its bamboo diet. The round face is the result of powerful jaw muscles, which attach from the top of the head to the jaw. Large molars crush and grind fibrous plant material.
About the size of an American black bear, adults measure around 1.2 to 1.9 m (4 to 6 ft) long, including a tail of about 10–15 cm (3.9–5.9 in), and 60 to 90 cm (2.0 to 3.0 ft) tall at the shoulder. Males can weigh up to 160 kg (350 lb). Females (generally 10–20% smaller than males) can weigh as little as 70 kg (150 lb), but can also weigh up to 125 kg (276 lb). Photo: wikipedia
