Clip Description

Also called the Unicorns of the Sea, narwhals are strange and beautiful creatures that can be found in the Arctic waters of Canada, Greenland, Norway and Russia. Males (and some females) have a distinctive spiralled tusk that protrudes from their forehead. This tusk, which is actually an elongated tooth, can grow to more than ten feet in length.

In this captivating clip, narwhals are journeying through cracks in the Arctic sea ice as they desperately need to reach new feeding grounds. The cracks (known as leads) can close at any time, cutting off their life-giving air supply. Furthermore, these narrow highways are only wide enough for one-way traffic. What do you think will happen when two pods of narwhals approach each other from opposite directions? Watch the clip to find out.
