Content: All about the narwhal tusk
The narwhal is famous among Greenland travellers as well as passengers on Svalbard voyages due to its long ivory tusk that spirals out counter clockwise. However, it is not a tusk like an elephant’s, but an upper-left canine tooth. Some male narwhal’s even have two of them, while only 15 percent of females have the tusk at all. Understanding the tusk’s purpose
To understand more about the narwhal tusk, scientists have partnered with various Arctic communities. By combining scientific research with Inuit knowledge, researchers aim to understand more about why the species have tusks and how they use them day-to-day. With more than 60 scientists integrating their research with Inuit knowledge, researchers have undertaken laboratory and field studies to investigate the physical and dental properties of the tusks. As the studies have an interdisciplinary nature, scientists have also conducted field expeditions and collected over 50 interviews with Inuit community members. One mystery scientists seek to uncover is why narwhal tusks break. Some of the knowledge collected regarding tusks breaking include descriptions of threatened narwhals immediately diving in shallow waters, hitting the sea floor, and breaking their tusks. The narwhal’s sonar
Recently scientists discovered that the tusk of the narwhal enables them to “see” like no other animal on Earth.
