Polar bears turn green at Japanese zoo

A polar bear, its fur stained with

algae, stands in its cage at Higashiyama Zoo in Nagoya, central Japan,

Saturday, Sept. 6, 2008. Three polar bears at the zoo changed their colors

in July after swimming in a pond with an overgrowth of algae, prompting

many questions from visitors concerned about whether the animals are sick

or carrying mold, a zoo official said. (Photo: yangtse.com)
