Narwhals play and forage using their amazing tusks

  • Narwhals in the Canadian High Arctic use their tusks for various activities such as foraging, exploration, and play, as shown in drone footage clips.
  • Researchers have used drones to gain insights into narwhal behavior, revealing how they target prey like Arctic char and engage in social behaviors.
  • Narwhals, known as unicorns of the sea, are primarily fish-eaters living in the frigid Arctic waters of Canada, Greenland, and Russia.
  • The narwhal tusk, a spiral-shaped tooth, grows continuously throughout their life and can reach lengths of up to 10 feet.
  • The tusks, possessing numerous nerves, also act as environmental sensors detecting water temperature and salinity.
  • Drone footage captured by researchers revealed narwhals wielding their tusks with agility to investigate and target prey like Arctic char.
  • Narwhals were observed using their tusks for play-like behavior, exploring objects like fish, and potentially exhibiting distinct personality traits.
  • Scientists noted the collaborative and possibly competitive behavior of narwhals using their tusks to interact with fish, including attempts to block others' access to prey.
  • Using drones to study narwhals offers a non-invasive method to understand their behavior and adaptability in response to environmental changes like climate change.
  • By observing narwhals in their natural environment without disturbance, researchers can gather crucial data on their responses to shifts in ice patterns and prey availability.
