A beluga whale that was first spotted nearly three months ago in the River Thames is still feeding healthily east of the British capital and facing a lone Christmas hundreds of miles from its normal Arctic habitat. “The whale pops up, and I am not exaggerating, for literally three to four seconds and then he disappears for 10 or 15 minutes and he moves in a wide, dark river, so you see how hard it is to track his precise location,” the spokesman said.
