Some high-end perfumes use a rare type of whale poop that costs more than silver

A small percentage of sperm whales produce ambergris, a clump of squid beaks and fatty secretions that likely exits through the whales' bowels. It's coveted by perfumers for its unique scent. Quality pieces of ambergris, which ambergris hunters snatch up as they wash ashore, can garner more than $7,000 a pound.
