Next, the researchers examined a second form of camouflage - disruptive colouration - in which highly visible boundaries on the surface of an animal break up its outline - in the panda's case the borders between the large black and white patches of fur. The results are consistent whether viewed by human, felid or canine vision models the last two represent panda predators. Also, infrequent pale brown pelage tones match ground colour, providing an intermediate colour which bridges the gap between the very dark and very light visual elements in the natural habitat. They discovered that their black pelage patches blend in with dark shades and tree trunks, whereas their white patches match foliage and snow when present. The international team analysed rare photographs of the giant pandas, taken in their natural environment. Perhaps the most famous of all however is the giant panda. While most mammals are drab browns and greys, there are a small number of well-known and intriguing exceptions such as zebras, skunks, and orcas. The results have been published today in Scientific Reports. Researchers at the University of Bristol, Chinese Academy of Sciences and the University of Jyväskylä have used state-of-the art image analysis techniques to demonstrate, counterintuitively, that the unique colourings work to disguise the giant panda.
