Antarctic Killer Whales Hunting Weddell Seals


NOAA scientists studying killer whales in Antarctic waters have found that these pack hunters prefer Weddell seals over any other prey. They often wash the seals off ice floes by creating waves or confusing them with their flukes or blowing bubbles underwater to make the surface turbid.

"These killer whales would identify and then attack Weddell seals almost exclusively, even though they made up only about 15 percent of the available seal population," said Pitman.

We’ve had several orca-hunting encounters of our own, including this one where a pack of Type B orcas train a juvenile in pack hunting.
