Narwhal+Facts!

 Narwhals, or Monodon monoceros (their scientific name), are a critically endangered type of whale. Climate change has greatly effected them. Like all whales, narwhals need to surface to breathe air. The effects of global warming has cause many rainstorms in the arctic, where narwhals live, which causes massive sheets of ice to form on the water. If the water if covered by ice than the narwhals have no way to get air.

 Narwhals are an amazing whale. They are very different than any other species of whale, but at the same time still very alike other species. While they are still mammals that swim and breathe air like other whales there are still a lot of noticeable differences. The biggest difference is probably their large tusk that looks a lot like a unicorn horn. This tusk is actually a tooth that grows and protrudes from the male narwhal's face. Sometimes a female narwhal's tooth will grow also, but it would be shorter. It's not known what these long tusks are actually used for, but many scientists believe they are used to either sense for fish around them.
