A narwhal is a member of the Monodontidae whale family. The narwhal has a body of a dolphin and swims on its back or belly up, and thus is called the corpse whale. Narwhals can be found in the Arctic ocean. They travel in small family groups, lay motionless for several minutes, are remarkably quick, communicate through squeals, whistles, clicks and trills. The name of the narwhal comes from an old German language from back in the middle ages called Old Norse words, which mean whale or corpse. The narwhal scientific name is Monodo monoceros and from research it is hard to tell who discovered the narwhal. However, it is believed that a man by the name of Carl Linnaeus discovered and documented narwhals in 1758.
This marine organism started the legend of the unicorn. The narwhal has a bluish-gray skin and males have a tooth up to 10 feet in length. It weighs around 1.8 tons and is around 16feet long. In medieval times, narwhal tusks that washed ashore were thought to be from the mythical unicorn. The tusks of the narwhal was considered to have healing powers that came from a horse. The narwhal is considered to be the unicorn of the ocean and is one of the rarest whales in the world.
