Narwhals spotted using tusks for non-mating fun

With their long, spiral tusks, narwhals (Monodon monoceros) look like something out of a fairy tale. Primarily seen in male narwhals, these single elongated teeth that can grow up to 10 feet. These gregarious whales typically travel in pods of two to 10 individuals, but are a bit elusive and difficult to study in the wild. Scientists believe that the tusks are primarily used in competition for mates, but that might not be the whole story. New drone evidence detailed in a study published February 28 in the journal Frontiers in Marine Science found that narwhals can use their tusks to forage, explore their surroundings, and even play.
