"Unicorns of the Sea"
Narwhals are often called the "unicorn of the sea" because of their unique horns, which only male narwhals have. A male narwhal's horn is actually one of its two teeth. All narwhals have two teeth, but the more prominent left tooth for male narwhals grows out from its upper lip to form an ivory, sword like tusk. Most tusks grow to be 9-10 feet long. The myth of the unicorn was started when people started finding narwhal horns that were washed up on beaches. Narwhal horns can sell for up to 5 times its weight in gold.
