While there are no animals that specifically hunt narwhals, some larger marine animals may occasionally prey on young or weak individuals:
* Polar bears: While polar bears are known to scavenge narwhal carcasses, there is no evidence they actively hunt them.
* Orcas (killer whales): Orcas are known to prey on various marine mammals, including beluga whales (close relatives of narwhals), but there is limited evidence they actively target narwhals.
* Greenland sharks: Greenland sharks are slow-moving, deep-water predators that could potentially prey on narwhals, but this is largely speculation.
Overall, narwhals are well-adapted to their Arctic environment and have few natural enemies. Their primary threats come from human activities such as climate change, pollution, and hunting.
