  • Unicorn Whales' Sonar Secrets: Narwhal Is the World’s Best Animal Navigator

    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.
