Meet our featured animal, the narwhal!

Here are five facts about narwhals:
- The horn on a narwhal is actually a giant, spiraled tooth.
- The long tooth can reach up to 3 m (10 ft.) in length and grows continually to replace wear.
- The name narwhal derives from the old Norse word nar meaning corpse.
- Narwhals travel in groups (or pods) of 15-20 whales.
- Preying on creatures primarily on the bottom of the sea, they dive on average 800 m (.5 mi.), but can go twice that.
There is not a great deal known about the narwhal, a whale most familiar for its long spiraled horn. Researchers are trying to change that by attempting to net and tag a narwhal in Greenland. Thousands of narwhals spend their summer in the cold waters off of Greenland’s shore.
