Narwhals

     The unicorn of arctic waters must be a fascinating site up close. Male narwhals have a huge tusk that seems to come out of its head, just like a unicorn. This makes scientists wonder what the purpose of the tusk is. Some suggest it helps them hunt. Talking about food, narwals hunt bottom dwelling fish in the winter and cod as well as other fish in the summer. These whales are usually between 3.5 to 4 meters long if you don't count the tusk. Like many whales, narwhals are social creatures living in groups that have between 15 to 20 members.
