The narwhal (Monodon monoceros) is famous for the long ivory tusk which spirals counter-clockwise several feet forward from its head. The tusk may play a role in male dominance and in addition, ongoing research by the WWF collaborators at Narwhal Tusk Research indicates that the tusk has sensory capability, with its millions of open sensory tubules.
The skin of the narwhal, called "maktaq" by Canadian Inuit, is eaten both raw and boiled, and the meat is eaten by the people, or fed to sled dogs. The tusk of the narwhal, made of ivory, is used for carving.Crafts made from this ivory are sold and can be an important source of income for Inuit artists.
Researchers are working with aboriginal groups to ensure that narwhal hunting is carried out in a sustainable way, so that populations remain stable.
For example, it is now believed that tusk has significant sensory capabilities, with up to 10 million nerve endings inside.


The tusk may also serve some role in male dominance hierarchies, and Inuit observations reveal significant differences in morphology and behaviour of narwhals in different parts of their range. Narwhals spend their lives entirely in Arctic waters of Canada, Greenland, Svalbard (Norway) and Russia.
In Baffin Bay-Davis Strait, the bulk of the world’s narwhals winter for up to 5 months under what appears to be total sea ice cover.
A new report from WWF details the problems increasingly noisy oceans are creating for whales. Fight the destructive harvesting and unregulated trade of one of the most attractive inhabitants of our tropical oceans. Where else can you get a gift that can mean so much, so easily, and in a fun and interesting way?


When you work with WWF to build a future in which humans live in harmony with nature, you give your child, and all children around the world, a chance to get to discover our earth as we know it today. Newborns are mottled blue-grey, juveniles are completely blue-black, adults are mottled grey and old narwhals are nearly all white. For centuries now, people have puzzled over the narwhal's unicorn-like tusk, and just what purpose it serves.
Martin Nweeia and science and Inuit colleagues involved with the Narwhal Tusk Research project has unearthed important new evidence.
