Inverted triangle, relatively flat. According to the Animal Encyclopedia, the panda's nose is an inverted triangle, relatively flat, black and a little moist. Panda is a herbivore among carnivores. Its staple food is bamboo, and its nose is flat and moist, which can help it better smell and taste the taste and nutrients of bamboo. Another important function of the panda's nose is to find mating objects through its sense of smell. Female pandas generally choose male pandas with good sense of smell to pair up.
