The giant panda has a black-and-white coat.Adults measure around 1.2 to 1.8 m (4 to 6 ft) long,including a tail of about 13 cm (5.1 in),and 60 to 90 cm (2.0 to 3.0 ft) tall at the shoulder.[13] Males can weigh up to 160 kg (350 lb).[14] Females (generally 10–20% smaller than males)[15] can weigh as little as 75 kg (165 lb),but can also weigh up to 125 kg (276 lb).[8][16]Average adult weight is 100 to 115 kg (220 to 254 lb).[17]
The giant panda has a body shape typical of bears.It has black fur on its ears,eye patches,muzzle,legs,arms and shoulders.The rest of the animal's coat is white.Although scientists do not know why these unusual bears are black and white,speculation suggests that the bold coloring provides effective camouflage in their shade-dappled snowy and rocky habitat.[18] The giant panda's thick,wooly coat keeps it warm in the cool forests of its habitat.[18] The panda's skull shape is typical of durophagous carnivorans.It has evolved from previous ancestors to exhibit larger molars with increased complexity and expanded temporal fossa.[19][20]
The giant panda's paw has a "thumb" and five fingers; the "thumb" – actually a modifiedsesamoid bone – helps it to hold bamboo while eating.[21] Stephen Jay Goulddiscusses this feature in his book of essays on evolution and biology,The Panda's Thumb.
The giant panda's tail,measuring 10 to 15 cm (4 to 6 in),is the second-longest in the bear family.(The longest belongs to thesloth bear.)[15]
The giant panda typically lives around 20 years in the wild and up to 30 years incaptivity.[22] The oldest captive,a female named Ming Ming,had a recorded age of 34.[23]
