Activists are Lame

     It's a scene that brings laughter and cheers from visitors to a Japanese aquarium - two white beluga whales wearing Santa hats.

The beluga whales have been fitted out with the cute Santa hats to entertain the crowds at the Hakkeijima Sea Paradise on Yokohama Island.

But environmentalists are saddened by the sight of what they say is the final humiliation for the whale and Greenpeace has labelled the performance as "unfortunate."
