The Narwhal is also called Narwhale - and rightfully so, as it is indeed a species of whale. It's a medium-sized whale, to be more specific. What makes this sea creature unique and extra special is that it has a really long tusk that makes it entirely different from other species of whales (and other sea animals, for that matter). Also, its tusk, which is similar to an elephant's tusk, is actually a tooth. Have you ever seen a tooth as big (and as long)? Needless to say, this creature's tusk is its main attraction. Some people see it as a sword - although that's not an accurate description with regards to its use since the Narwhal really doesn't use its tusk as a weapon. There is something really special about the shape and overall structure of the Narwhal's tusk though. Their tusks were actually worth a lot of money in the past because they were sold as Unicorn's horns. Since a Unicorn is a magical creature, their horns are thought of as magical and lucky. Moreover, because of their Unicorn-like tusk, Narwhals are also called Unicorns of the Sea - even to this very day. Have you seen a Narwhal? Would you like to meet it? You can get to know it better and see it up close through the pages of this book.
