Are Narwhals Endangered?

Content: Narwhals have a fairly restricted and specialized diet. Their prey is mostly composed of Greenland halibut, polar/Arctic cod, cuttlefish, shrimp and armhook squid. However other items found in the stomachs of narwhal have included wolffish, capelin, skate eggs and even rocks. Narwhals are believed to feed by swimming towards prey until it is within close range and then sucking it with considerable force into the mouth. One study published in the Canadian Journal of Zoology tested 73 narwhals of different age and gender to see what they ate. The study conducted in 1978 found that the Arctic cod made up approximately 51% of the diet of the narwhals, with the next most common animal being the Greenland halibut (consisting of 37% of the weight of their diet). Deep-water fish such as halibut, redfish and polar cod have also been found in the diet of the males. This means that the narwhals can dive deeper than 1,600 ft (500 m) below sea level. The study also found that the dietary needs of the narwhal did not change among genders or ages. Narwhal Tusks
The most prominent feature of the male narwhal is a single long tusk, which is actually a canine tooth that projects from the left side of the upper jaw, through the lip and forms a left-handed helix spiral.
