(Ⅲ)        Walking along the beach in Dorset with his dad, the boy found something looked like a rock. He and his dad used Google to help to know what it is. The rock was actually an ambergris. Weighing more than a pound, it is said to be worth up to U.S. $63,000.       The price of ambergris is high because it is hard to be collected. Ambergris is made by sperm whales. Squid is the main diet of sperm whales but its beak can't be digested by sperm whales. Therefore, sperm whales digest these beaks by coating them with ambrein. Ambergris, thus, is a mixture of squid beaks, ambrein and another digestive product inside the sperm whales. When sperm whales vomit, they also throw ambergris up. There is little chance of finding ambergris because only one of a hundred sperm whales has ambergris. Although it sounds terrible to collect what sperm whales vomit, many people still love ambergris because of its good smell.
