Most of their communication is accomplished through scent marking throughout their habitat and territory. During mating, they become very vocal, relying on extremely detailed vocalizations to express all shades of mood from amorous to angry. Giant pandas do occasionally vocalize when playing. Giant pandas live in dense, fog-enshrouded stands of bamboo that obstruct a direct line of sight and any potential visual communications. It is thought that giant pandas never developed these visual accessories due in part to their habitat and solitary nature.
They have no crest or mane to erect, and their ears are not flexible enough to cock forward or flatten. Their tails are stubs and therefore cannot flag signals to other giant pandas. Giant pandas do not exhibit body characteristics that communicate visual signals. Many people find these chunky, lumbering animals to be cute, but giant pandas can be as dangerous as any other bear. Giant pandas have large molar teeth and strong jaw muscles for crushing tough bamboo. The panda's thick, wooly coat keeps it warm in the cool forests of its habitat. It is a highly specialized animal, with unique adaptations. The giant panda has lived in bamboo forests for several million years. Unfortunately, there is no one conclusive theory as to why giant pandas are black and white. Another theory suggests that the black absorbs heat while the white reflects it, helping giant pandas maintain an even temperature.
Another thought is that the pattern may accentuate social signals in some way, or help giant pandas to identify one another from a distance so they can avoid socializing, as they are typically a solitary animal. This theory does not work, however, when considering that giant pandas have no natural enemies to hide from. In patches of dense bamboo, an immobile giant panda is nearly invisible, and virtually disappears among snow covered rocky outcrops on a mountain slope. Although scientists do not know why these unusual bears are black and white, some speculate that the bold coloring provides effective camouflage. It has black fur on its ears, eye patches, muzzle, legs, and shoulders. The giant panda, a black-and-white bear, has a body typical of bears.
