For the first time ever, there's video footage of narwhals using their long tusks in a hunt.
Narwhals are a species of toothed whale that are most closely related to the beluga whale. The males have evolved an extra long left canine tooth that can grow up to 2.7 meters or 9 feet long and bursts through the upper lip and protrude from the head like the horn of a unicorn. In a research published in PLOS One, it was revealed that narwhals have the most directional sonar of any species on Earth.
Scientists from McGill University in Montreal, Canada, recently learned a little more about the elusive marine creatures known as narwhals by focussing on newborns.
Narwhal's use their toothy horn in unique ways. Contrary to popular opinion, however, hunting is not one of them. Here's what it's really used for.
Using a new, specialized net, a team of researchers recently collected polar cod (Boreogadus saida) from their icy homes in order to better understand the fishes' large-scale distribution and origin as well as the predators that feed on them.
