Moscow Zoo’s Polar Bear Surprises Visitors With Green-Tinted Fur

A polar bear named Terpey was spotted with greenish fur at the Moscow Zoo. A video showing the animal was published by Novosti Moskvy Telegram channel. However, the unusual appearance is considered normal. The fur of polar bears is hollow, and the hairs are filled with air, which helps the animals retain heat. During warmer periods, microscopic algae can settle and grow inside these hollow structures, causing the fur to take on a greenish tint. This does not indicate illness or any health problems in the animal.
