red panda shares this feature with the giant panda, which has a larger sesamoid that is more compressed at the sides. In addition, the red panda's sesamoid has a more sunken tip while the giant panda's curves in the middle. These features give the giant panda more developed dexterity. The red panda's skull is wide, and its lower jaw is robust. However, because it eats leaves and stems, which are not as tough, it has smaller chewing muscles than the giant panda. The digestive system of the red panda is only 4.2 times its body length, with a simple stomach, no noticeable divide between the ileum and colon, and no caecum. Distribution and habitat The red panda inhabits Nepal, the states of Sikkim, West Bengal and Arunachal Pradesh in India, Bhutan, southern Tibet, northern Myanmar and China's Sichuan and Yunnan provinces. The global potential habitat of the red panda has been estimated to comprise at most; this habitat is located in the temperate climate zone of the Himalayas with a mean annual temperature range of . Throughout this range, it has been recorded at elevations of . In Nepal, it lives in six protected area complexes within the Eastern Himalayan broadleaf forests ecoregion. The westernmost records to date were obtained in three community forests in Kalikot District in 2019. Panchthar and Ilam Districts represent its easternmost range in the country, where its habitat in forest patches is surrounded by villages, livestock pastures and roads. The metapopulation in protected areas and wildlife corridors in the Kangchenjunga landscape of Sikkim and northern West Bengal is partly connected through old-growth forests outside protected areas. Forests in this landscape are dominated by Himalayan oaks (Quercus lamellosa and Q. semecarpifolia), Himalayan birch, Himalayan fir, Himalayan maple with bamboo, Rhododendron and some black juniper shrub growing in the understoreys. Records in Bhutan, Arunachal Pradesh's Pangchen Valley, West Kameng and Shi Yomi districts indicate that it frequents habitats with Yushania and Thamnocalamus bamboo, medium-sized Rhododendron, whitebeam and chinquapin trees. In China, it inhabits the Hengduan Mountains subalpine conifer forests and Qionglai-Minshan conifer forests in the Hengduan, Qionglai, Xiaoxiang, Daxiangling and Liangshan Mountains in Sichuan. In the adjacent Yunnan province, it was recorded only in the northwestern montane part. The red panda prefers microhabitats within of water sources. Fallen logs and tree stumps are important habitat features, as they facilitate access to bamboo leaves. Red pandas have been
