DO WHALES DREAM OF OCEANIC SHEEP?

During the first spring of her stay at SeaWorld, J. J. was always found floating off to one side of her pool, and caretakers feared that she was perhaps suffering from boredom and depression. It soon dawned on them, however, that she was facing north, the direction of the gray’s spring migration. Subsequent necropsies on gray-whale brains revealed that they contain tiny particles of magnetic iron oxide, inner navigational ball bearings of a sort that whir in concert with the earth’s magnetic fields, guiding the whales toward their Arctic feeding grounds and, in the early winter, back down to Baja’s birthing lagoons. (Russian scientists, meanwhile, conducted sleep studies on J. J. and found the first definitive evidence that whales do, in fact, dream.)
