Arena - Philip Hoare's Guide to Whales - Toothed

Acclaimed author and whale-watcher Philip Hoare takes us into the world of toothed whales, from the plight of the captive killer whale to the fate of the stranded London whale. In the deep waters off the mysterious islands of the Azores, he encounters common dolphin swimming spectacularly in the clear ocean, and the world's greatest predator, the sperm whale, which once provided man with oil and light.
