1. Narwhal
If you see a herd of unicorns in icy waters, they are surely narwhals. These magnificent creatures are species of whales, who live in Arctic waters. The long tusk, that makes narwhals looking so unique and adorable, is a long, spiral-shaped tooth, which can grow up to 3 meters and weight 10 kilograms! However, the function of it is still undefined. The tusk might be a battle sword or special masculine attraction to get more females, although recent research discovered its high sensitivity, so it might as well serve as a thermometer or barometer.
