Arctic Blog’s Animal of the Day: ‘The Narwhal’
These fascinating creatures, known as the ‘unicorns of the sea’ are thought to have started the myth of unicorns on land, due to their horns getting washed up on beaches!
Nobody knows quite what narwhals use their horns for. It has been suggested that they possibly are used to spear food, fight other males or for defence.
They inhabit Arctic seas at all depths and tend to stay close to pack ice, where they maintain breathing holes through the sheets of ice.
