Narhwals are cousins of the beluga whales but with a big tusk. Narwhals usually live in groups. They can stay underwater for 20 minutes. The narwhal tusk is made for fighting but some scientists think that it is made for impressing or attracting females. You can easily tell who is a female and who is male. The difference is that the male has a bigger tusk and the female has a smaller or no tusk. The tusk is not a horn but it is actually a tooth that is connected to the skull. In one year, there are 500 narwhals with 2 tusks. Scientists are not sure why they have 2 tusks.
