SPERM WHALES

The sperm whale is a toothed whale that lives in pods. It has a huge brain that weighs about 20 pounds (9 kg); it is the largest brain of any animal. The sperm whale has a single blowhole that is s-shaped and about 20 inches long. The blowhole is located on the left side of the front if its huge head. The sperm whale has a 4-12 inch thick layer of blubber. They produce ambergris, a dark, waxy substance (related to cholesterol) that is produced in the lower intestines, and is sometimes found containing squid beaks. Ambergris may help protect the sperm whale from the stings on the giant squid, its major food. Large lumps of ambergris may be vomited up by the sperm whale.
