The involuntary feeding of whales

Just one interesting tidbit from a fascinating NYT article on whales:

Whales display an incredible degree of coordination and cooperation in their efforts. Aaron Thode, an associate research scientist from the Scripps Institution, who was in Baja doing acoustical studies of grays, told me of another project he is involved in, using the latest research tools to gain insights into how whales perceive the world. He showed me an extraordinary video of sperm whales pilfering catch from fishermen’s lines in Alaska, 50-foot-long, massive-jawed behemoths delicately snatching a single black cod from a longline’s dangling hook, like an hors d’oeuvre from a cocktail toothpick. Fishermen are currently losing 5 to 10 percent of their yearly haul and fear the problem could become worse because whales who have mastered the technique are busily teaching it to others. The news seems to be rapidly spreading, as reports of similar fish-snatching are coming in from fishermen all over the world.
