What happens to the bones of whales when they die in the ocean?

There was a story on BBC's Blue Planet about exactly this. Essentially, it sinks to the ocean floor, where it becomes a beacon of life in an otherwise barren desert of lightless sand. Sharks are the first to feast, ripping off chunks of the carcass, while scavengers like crabs move in for the remainder. Many different types of life will feast on the remains for over a year, eventually leaving a completely clean skeleton on the ocean floor to eventually be ground to dust.
