Polar bears at Singapore Zoo turn green
It's a wee bit early for St. Patrick's Day, but Singapore Zoo's two polar bears have turned green.
"The harmless algae is the result of Singapore's warm and humid tropical conditions," Tan said. Polar bears have clear hair shafts that appear white because they reflect light. Sheba's coat was successfully bleached with hydrogen peroxide 2.5 weeks ago and Inuka will be given a similar treatment in three weeks, Tan said. The zoo wanted to observe Sheba's reaction to the treatment before bleaching Inuka, he said. For now, Inuka remains mottled with bright grass-colored splotches behind his ears, on his back and legs. Three polar bears at the San Diego Zoo developed similarly green coats in 1979 but were cured with a salt solution, according to the Web site of Polar Bears International, a nonprofit conservation group based in North America. |
