What is the gray whales predators?

Gray whales have very few natural predators in the open ocean, especially when they are adults. This is due to their large size and the fact that they are primarily bottom feeders in deeper waters.

However, there are some threats they face:

* Orcas (Killer Whales): Orcas are known to prey on gray whales, particularly calves and juveniles. They are the most significant threat to gray whales.

* Polar Bears: Polar bears can sometimes attack gray whales in shallow waters, especially when the whales are migrating along the coast.

* Sharks: While rare, large sharks like Great Whites and Tiger Sharks can occasionally pose a threat to gray whales.

* Humans: Human activity, including fishing gear entanglement, vessel strikes, and pollution, can also pose a threat to gray whales.

It's important to note that these threats are infrequent and don't significantly impact the overall gray whale population. Gray whales have adapted to their environment and have a relatively low risk of predation in the wild.
