Japanese whalers apparently have a new technique to get rid of environmental activists - dropping iron grappling hooks on their inflatable boat.
Three members of the Sea Shepherd group were injured in the latest conflict in the Southern Ocean.
But captain of the Steve Irwin, Paul Watson, says they've managed to disrupt the whaling season, and the whalers are getting frustrated:
"We're confident it's not going to be a very good season for them, but they're getting increasingly more angry and more aggressive," he says.
More confrontations are expected as the activists continue to pursue the whalers.
