Often dubbed the unicorns of the sea, narwhals are strange and beautiful creatures with long tusks protruding from their heads. The narwhal tusk — most commonly found on males — is actually an enlarged tooth with sensory capability and up to 10 million nerve endings inside. Some narwhals have up to two tusks, while others have none. The spiraled tusk juts from the head and can grow as long at 10 feet. This beautiful narwhal headband celebrates this beautiful and graceful ocean mammal.
