Transcripts - Narwhal integrated studies
The Narwhal lives in the Arctic where it is cold year round and its one of the toughest places for anything to live. It has a thick layer of blubber around its body to protect it from the cold. For them to the communicate through icy water they make high pitched clicking sounds. They can hold there breath up to 20 minutes underwater to stay hidden from predators. It has a very flexible neck so it can capture prey faster. There tusks have at least 10 million nerves in them and scientists think they use it to measure thickness of the ice, temperature, pressure, to make holes in ice, and reproduction. They can survive 3 hours a day 800 meters deep where there’s a lot of pressure.
