Narwhals are real animals. They are a type of medium-sized whale. The narwhal is known for its distinct tusk, which is actually a canine tooth that protrudes from its forehead.
Narwhals are found in Arctic waters around Greenland, Canada and Russia. They range from 13 to 18 feet long and weigh 1,800 to 3,500 pounds. Narwhals are the closest living relative to the beluga whale. They live in pods of five to 10 narwhals. They are carnivores that eat different types of fish, shrimp and squid. Narwhals are being threatened by people. They are also hard to keep in captivity.
