Narwhals are not considered to be dangerous animals, as they generally avoid contact with humans. However, here is a funny fact about Narwhals :

“Narwhals have been known to use their long tusks to tap on the ice to check for thin spots, but if you’re ever worried about getting speared by a narwhal tusk, just remember that they’re actually more likely to use them for showboating and impressing potential mates.”
