"Tooth-brushers?
Just like humans, Narwhals brush their teeth.
The narwhal’s tusk, or modified tooth comprises 10 million tiny nerves.
Tusking - in which two males rub their tusks together - may therefore be a way of cleaning encrustations from the surface, just like brushing teeth.
Other theories on \"tusking\" are that it is a form of aggression similar to medieval jousting.",
"Corpse whales?
Narwhals are born a gray color, darken as a teenager, and whiten with age.
The word \"narwhal\" comes from the Old Norse meaning \"corpse whale\" since its white color resembles that of a floating corpse.
Narwhals are hunted by Inuit people for their skin, oil, meat, and tusks.",
"Into the icy depths...
Narwhals can dive for up to 20 minutes.
They make their home in the icy waters of the Arctic sea, and rarely stray far from the ice.
In summer they occasionally venture into estuaries, deep fjords, and bays.
They dive for between 7 and 20 minutes at a time.",
"Big babbies.
At birth narwhals weigh about 175 pounds. When born they measure about 5 feet long.
They grow much larger than this, adult males grow to about 16 feet long and weigh about 1.8 tons.
Females are slightly smaller than males, averaging 13 feet long, and one ton in weight.",
"Unicorn?
It is believed that narwhal sightings started the unicorn legends.
The tusk is between 7 and 10 feet long and is usually twisted in a counter-clockwise direction.
The tusk is a formidable jousting weapon in courtship and rivalry for male dominance.
It is also useful in obtaining food, and for amplifying sonar pulses.",
