Definition: Narwhaling, also known as whaling or whaling of marine whales, is a form of commercial fishing in which humans catch and sell whale meat. The practice began in the 18th century when the English explorer Robert Hare went whale-hunting for food. Today, it involves the killing of thousands of adult, female killer whales every year to obtain their flesh, fins, and blubber. Whales are large marine mammals that can grow up to 20 feet long
