The narwhal lives in the Arctic where its thick layer of blubber and ability to stay underwater for over 20 minutes helps it survive in the cold conditions. Its tusk contains many nerves and is used to detect ice thickness, temperature, and pressure and for reproduction. Narwhals are related to extinct four-legged whales and are the only whale with a tusk, which can grow over 8 feet long.

2.  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.

4.  The Narwhals oldest extinct
