Content: Diet of the Narwhal
Narwhal feed primarily on Greenland halibut, Arctic cod, cuttlefish, Polar cod, squid, and shrimp. Scientists believe that they feed by using strong suction to force prey into their mouths. These animals only have two canine teeth, one of which is a tusk, so it is unlikely they can capture prey in any other way. Narwhal Tusk Purpose
Until recently, the purpose of a narwhal’s tusk had been shrouded in mystery. Many scientists hypothesized its possible uses, but there simply hadn’t been enough research done to make a strong conclusion. New studies and video footage have given scientists a better understanding of the function of the tusks. Research has shown that these elusive marine animals can detect chemical changes in the water around them using their tusks. Because the tusk is a tooth, it contains very sensitive nerve endings. These nerve endings have the ability to detect changes in the chemical composition of the water, including salt concentrations. They have also been seen using their tusks to “smack” fish, effectively stunning them.
