In the past, whalers have sought out the Sperm whale for the valuable spermaceti oil, which makes an extremely fine lubricant. They are amongst the most intelligent creatures on Earth; they have large brains, show complex behaviour including the ability to teach others and learn from one another. The bowhead whale is another species of baleen whales found in the arctic and the sub-arctic waters. Humpbacks, blue whales and fin whales are gulpers; their throats are expandable and enable them to take enormous mouthfuls of seawater and sieve out their prey; gray whales are bottom feeders and sift prey from mouthfuls of mud on the seabed.
