  In Moby Dick, Herman Melville wondered how - or what - whales see with eyes
on opposite sides of their heads. "It is plain that he can never see an object
which is exactly ahead... Is his brain so much more comprehensive, combining
and subtle than man's that he can at the same moment of time attentively
examine two distinct prospects, one on one side of him, and the other in an
exactly opposite direction?" he asked. It's a good question. But if Melville
were alive today he might have pondered something perhaps even more intriguing:
Can whales see the stars?
