Scientists admit they are baffled by a rise in aggressive orca activity, with the whales ramming boats along the Spanish and Portuguese coasts, according to reports by the Guardian. Researchers speculate that it might be competition for tuna populations along the coast that has led to some distress among the whale populations. Alfredo Lopez, coordinator for the Study of Marine Mammals in Galicia, said orcas make their way up the coast each September to chase tuna. “We see marks caused by fishing lines,” Jörn Selling, a marine biologist for Firmm whale watching and research foundation, told the Guardian. "I've seen these orcas grow from babies, I know their life stories, I've never seen or heard of attacks."
