The narwhal is perhaps one of the most recognizable whale to the public as it may be the basis of the legend of the unicorn. Despite this, little is truly known about this almost mystical creature. The narwhal is a migratory animal, but not much is known as to its migration routes. Preferring cold waters, the narwhal frequents Canadian arctic waters. Narwhals are often victims of poachers, as their long tusks are valued as ivory and fetch a fair sum of money on the black market. Narwhals feed on a variety of cephalopods and fish.
