There's a popular idea that narwhals use their long tusks to spear food, like a nautical kebab. The reality is even stranger

Reputation: Narwhals are mythical creatures – unicorns of the sea. They are "toothed whales" so obviously have teeth in their mouths. They spear their food, and are as aggressive and dangerous as they look. Reality: Narwhals are not mythical. They do not have teeth in their mouths, but their characteristic tusk is actually an overgrown tooth. They do not catch food by spearing it. They are shy and skittish.
