Green polar bears

Algae-dyed polar bears puzzle Japan zoo visitors

TOKYO - Green-coloured polar bears are drawing questions from puzzled visitors at a Japanese zoo.

Three normally white polar bears at Higashiyama Zoo and Botanical Gardens in central Japan changed their colour in July after swimming in a pond with an overgrowth of algae.

The sight of green polar bears has prompted many questions from visitors concerned about whether the animals are sick or carrying mould, zoo official Masami Kurobe said Sunday.
