Battlestar Galactica star Jamie Bamber is going naked to save the Canadian Black Bears.

The actor, who plays Captain Lee “Apollo” Adama on the popular Sci-Fi Channel series, has teamed up with People for the Ethical Treatment of Animals to call attention to the slaughter of Canadian Black Bears, which are used to make the ceremonial caps worn that are worn by the Queen of England’s Royal Guard.

“The obvious alternative is to make caps out of faux fur. You know, use synthetic materials to avoid killing a beautiful animal,” Jamie says. “They’re not to keep warm. It’s not particularly freezing outside Buckingham Palace. You could wear something else. And you could certainly wear faux fur.”

Jamie’s PETA ad is not the first time the actor has gone without clothes. Fans of the show will fondly remember “Apollo’s” infamous locker room scene, where the actor barely sported a towel.
