A review study about the role hair plays in collecting dirt on animals and insects and the roles it plays in helping to keep them clean. A honeybee and a squirrel have the same amount: 3 million. A beaver has about 300 million. A moth has 10 billion. The study also identifies true surface area: the total area where dirt can possibly collect on an animal. A sea otter has the true surface area of a hockey rink.
