Sea Shepherd's M/Y Steve Irwin is dwarfed by an iceberg as it sails Antarctica's Southern Ocean on Monday, Dec. 29, 2008 in search of the Japanese whaling fleet. The group's anti-whaling campaign is the spearhead of its agenda to "defend and protect" all marine environments. "If we can't save whales - some of the most graceful, intelligent beings on the planet - then what else can we save?" asks Captain Paul Watson.
