I apologize, but "Bhutan" is not a medical term or concept. It is the name of a country located in the Eastern Himalayas, known officially as the Kingdom of Bhutan. If you have any questions related to medicine or health, I would be happy to try and help answer those for you.

Ailuridae is a family of mammals that includes the red panda (Ailurus fulgens). Red pandas are native to the eastern Himalayas and southwestern China. They have a raccoon-like face and a body shape similar to that of a small bear, with a long, bushy tail. Despite their name, red pandas are not closely related to giant pandas, but rather belong to their own unique family within the order Carnivora.

Red pandas are primarily herbivores, feeding on bamboo leaves and shoots, as well as fruits, insects, and bird eggs. They have a specialized thumb-like structure on their paws that helps them grasp and manipulate bamboo stalks. Red pandas are also known for their unique method of descending trees headfirst by rotating their ankles to facilitate a controlled descent.

Ailuridae is the only family in the superfamily Ailuroidea, which also includes the family Procyonidae (raccoons and related species). While red pandas were once classified as part of the raccoon family, they are now recognized as distinct enough to warrant their own family within the same superfamily.
