 It's been two weeks since a whale washed ashore on a South Island beach in New Zealand, and there may be a silver lining in that otherwise sad incident because scientists there say that whale could be the world's rarest. According to New Zealand's Department of Conservation, no live sighting of this particular whale species has ever been recorded. No one knows what it eats or where it lives, and no one has ever been able to get a good look at a dead one because they're usually buried.
