Call me Ishmael. Some years ago – never mind how long precisely – having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world. So begins Herman Melville’s epic struggle between man and the great leviathan. Of course Melville died in poverty and obscurity, never knowing he had written the great American novel, but the mighty sperm whale lives on (despite the best effort of Yankee whalers to the contrary). Of all the great whales this species has captured my imagination (and camera) the most. Here is just a beautiful glimpse at sunset in the Gulf of California (Sea of Cortez), Mexico.
