Narwhal on an Arctic cruise
What you need to know about the Narwhal
The narwhal is a magical-looking creature, like a cross between a whale and a unicorn. Males most commonly have tusks, and some may even have two. The tusk, which can grow as long as 10 feet, is actually a large tooth. Research indicates that the tusk has sensory capability, with up to 10 million nerve endings on the inside. The tusk may also play a role in the ways males show dominance.
Interesting facts about Narwhal
Narwhals can be found in the Arctic waters of Canada, Greenland, Norway and Russia. The majority of the world’s narwhals live under sea ice for up to five months in the Baffin Bay-Davis Strait area. They use the cracks in the ice to breathe when needed, especially after dives, which can be up to over a mile deep. They feed mainly on Greenland halibut, along with other fish, squid and shrimp.
