Do killer whales eat bowhead whales?
For the first time, scientists have direct evidence that killer whales are preying on bowhead whales in the U.S. Pacific Arctic. A dramatic loss of sea ice in recent years may be leaving bowheads more vulnerable to killer whale predation.
What animal eats a sperm whale?
Orcas
Orcas are the largest natural threat to sperm whales, though pilot whales and false killer whales are also known to hunt them. Orcas go after entire sperm whale pods and will try to take a calf or even a female, but the male sperm whales are generally too big and aggressive to be hunted.
What eats an orca?

Orcas are the largest of all carnivores on earth that feed on a wide variety of foods, they are found in almost all oceans, from the tropics to the Arctic and Antarctic where they will go deep into the pack-ice to hunt seals and penguins. They are commonest in coastal waters and in cool temperate and sub polar seas.
Do killer whales live in the Arctic?
Killer whales (Orcinus orca) aren’t necessarily newcomers to the Arctic. The killer whales’ presence in the Arctic is proving consequential to other species, including the narwhal (Monodon monoceros), which has become a primary food source for killer whales during the open-water season in the Arctic.
What do orcas fear?
“It’s very unusual that they’re afraid of anything—or seemingly afraid.” Interactions between killer and pilot whales have only been scientifically documented a few times, and Samarra is among the first scientists to have observed this behavior in Iceland.
Do orcas eat blue whales?
The only sea creature known to attack blue whales is the orca whale (scientific name: Orcinus orca) also known as the “killer whale”. They have been known to work in groups to attack blue whales. But blue whales probably see orcas as more of a pest than a predator.

What are orcas afraid of?
Do killer whales prey on bowhead whales?
For the first time, scientists have direct evidence that killer whales are preying on bowhead whales in the U.S. Pacific Arctic. A dramatic loss of sea ice in recent years may be leaving bowheads more vulnerable to killer whale predation.
Do bowhead whales live in the Arctic Ocean?
Bowhead whales are one of the few whale species that reside almost exclusively in Arctic and subarctic waters experiencing seasonal sea ice coverage, primarily between 60° and 75° north latitude. Of all large whales, the bowhead is the most adapted to life in icy water.
How do bowhead whales break through ice?
Bowhead Whales can use their large and powerful skull to break through ice that is up to 24 inches thick. Even though it is quite large, they are able to leap completely out from the water. A Bowhead Whale has two blow-holes. The Bowhead Whale’s scientific name is Balaena mysticetus.
