Kinship is another matter. Naturalists first filed it with raccoons, then with bears, before genetic research gave it a family of its own: Ailuridae, of which the red panda is the only living member. Its closest living relatives are probably in the group that includes skunks, raccoons and weasels. Both pandas share a "false thumb," an enlarged wrist bone called the radial sesamoid that works like an opposable digit for gripping bamboo. Fossils of a Miocene red panda relative found in Spain show it already had one of its own, so the two thumbs evolved independently. ## A Full-Time Bamboo Job Bamboo makes up about 95 percent of a red panda's diet, and unlike a giant panda, which eats nearly every above-ground part of the plant, a red panda feeds selectively: choosing the most nutritious leaf tips and, when available, tender shoots. Its gut can extract only about 24 percent of the bamboo it eats, so it needs to eat 20 to 30 percent of its own body weight every day, roughly 2 to 4 pounds (1 to 2 kilograms). A red panda rounds out the diet with berries, blossoms, eggs, insects, and occasionally a small rodent. ## Built for the Cold and the Climb San Diego Zoo Wildlife Alliance puts adults at 20 to 25 inches (51 to 64 centimeters) long, not counting a tail of 11 to 19 inches (28 to 49 centimeters) that makes up almost half the animal's total length. It gives females 6 to 10 pounds (3 to 4.5 kilograms) and males 10 to 14 pounds (4.5 to 6.2 kilograms), while Smithsonian's National Zoo says adults typically weigh 8 to 17 pounds (3.6 to 7.7 kilograms). They differ on lifespan too: San Diego says a red panda typically lives eight to ten years, and up to 15 in zoos; the Smithsonian says they may live as long as 23. Dense fur covers even the soles of its feet, helping it climb wet, slippery branches and walk on icy rocks. Extremely flexible ankles, with a fibula that can rotate on its own axis, let it climb straight down a tree trunk headfirst. In the cold it curls into a tight ball to conserve body heat, and its long, bushy tail helps shield it from harsh cold and wind. > **A Nose Built Into the Tongue** A red panda tests odors using the underside of its tongue, which has a cone-like structure for collecting liquid and carrying it close to a gland inside its mouth. It is the only carnivore with this adaptation. ## One Name, Two Species? A study of 65 whole genomes argues that "the red panda" is really two species: a Himalayan red panda and a Chinese red panda. The two split apart about 220,000 years ago, around the time a glaciation bottlenecked both populations. The IUCN Red List, which assessed the red panda as a single species in 2015, lists it as Endangered. San Diego Zoo Wildlife Alliance says red panda numbers may have fallen by as much as 40 percent over the last 50 years; Smithsonian's National Zoo says researchers believe the population fell 40 percent in the past two decades. Estimates of the surviving population range from about 2,500 to 10,000 adults. ## Frequently Asked Questions ### What is a red panda's 'false thumb', and what does it do? It is an enlarged wrist bone, the radial sesamoid, that works like an opposable thumb for gripping bamboo. The giant panda has one too, but a Miocene red panda relative found as a fossil in Spain already had a false thumb of its own, which indicates that the two thumbs evolved independently. *(Source: [Salesa et al. 2005]())* ### Are red pandas closely related to giant pandas or raccoons? Neither, exactly. They were first classified with raccoons, then, citing some agreement in DNA, moved in with bears, but genetic research now places them in their own family, Ailuridae, of which they are the only living member. They are probably most closely related to the group that includes weasels, raccoons and skunks. *(Source: [Smithsonian's National Zoo and Conservation Biology Institute]())* ### How does a red panda survive freezing Himalayan winters? Dense fur covers even the soles of its feet, helping it climb wet, slippery branches and walk on icy rocks, and its bushy tail, almost half its total body length, helps shield it from harsh cold and wind. In cold weather a red panda curls into a tight ball to conserve body heat. *(Source: [San Diego Zoo Wildlife Alliance]())* ### Why doesn't the cyanide in bamboo poison red pandas? Bamboo contains toxic cyanide compounds, and members of the order Carnivora, which includes the red panda, have low levels of a key cyanide-clearing enzyme in their tissues compared with plant-eaters. A red panda's gut bacteria may pick up the slack: in one study, they were significantly richer in genes likely to code for cyanide-degrading enzymes than the gut bacteria of typical plant-eating mammals, one of the traits red pandas share with the giant panda for coping with a bamboo diet. *(Source: [Zhu et al. 2018]())* ## Sources 1.
