A narwhal is a kind of porpoise. It lives in the Arctic Sea. Narwhals are found near the coasts and sometimes in rivers. They have only two teeth. In males, the top tooth grows to be rather large. The tooth can grow to be nearly
ten feet (3 meters) long. This makes the narwhal look like a unicorn. Narwhals are carnivores, but they do not use
their teeth to hunt. They feed on fish, shrimp, and other small marine life. Like dolphins, they often travel in
groups. In rare cases, narwhal groups can have hundreds or even thousands of members.
