What eats a narwhal?

Narwhals are marine mammals that live in the Arctic waters around Greenland, Canada, Norway, and Russia. They are apex predators, meaning they are at the top of the food chain and have no natural predators. However, narwhals are hunted by humans for their meat, blubber, and tusks. Polar bears and orcas are also known to prey on narwhals, particularly young and weak individuals.
