In this photo released by the Institute of Cetacean Research of Japan, an activist of the Sea Shepherd Conservation Society throws a bottle which the Japanese whalers said contains butyric acid towards the Japanese whaling ship Shonan Maru No. 2 as another activist, right, sends what appeared to be a green laser from the deck of the anti-whaling group's vessel Steve Irwin during their encounter in the Antarctic Ocean on Tuesday, Dec. 22, 2009. The Japanese whaling fleet left Japan last month for the annual 'research whaling' in the Antarctic Ocean.
