Penguins WWF Wall Calendar: Penguins are remarkable creatures that have adapted successfully to some of the harshest environments on earth—the Adelie and the emperor penguins inhabit regions too frigid to support almost any other known life form. This fascinating calendar includes images of these two hardy species along with kings and chinstraps and gentoos foraging, preening, courting, parenting, and more. In the U.S. and Canada, World Wildlife Fund (WWF) receives 50 cents for each 2014 WWF calendar purchased, with a guaranteed contribution of $50,000. EAN: 9781620211106
