Narwhals



Narwhals inhabit the cold waters around Arctic regions, and can be found along most coastal areas of Greenland. An adult male reach an average length of about 5 m and can weigh as much as 1600 kg, the female is somewhat smaller than the male. The back is greyish and speckled, with a lighter coloured belly, and the dorsal fin is missing. The male has a very characteristic tusk, which are the left front tooth that has grown through the upper lip.
These tusks are about 1.5-3 m long and are used as swords, when the males are battling over the rights to mate with females. For many hundreds of years, people thought that these tusks came from fabulous animals, for example the Unicorn. The narwhal feeds on fish, squids and crustaceans. Female reaches sexual maturity at the age of 4-7 years, while the males are older, 8-9 years.
