Killer Whale attack in the Southern Ocean

12/04/14 - Searching the waters on the west side of the Antarctic Peninsula the National Geographic Explorer encountered a pod of Type A Killer Whales trying to separate a Minke whale calf from its mother.


Type A Killer Whales are the largest of all Killer Whale on our planet. Easily recognized by their very large white eye patch, these apex predators are known for their keen strategies that succeed in taking down much larger prey.

Successfully separating the calf from its mother, the pod decided to split. Half staying to begin the work of drowning the Minke calf, while the others pursued the mother to see if they could add her to the menu.

In perfect unison, the pod toppled upon the calf. Denying it the ability to break the surface in order to breathe. Here we see the calf lunging for air as the pursuit continues.


Greatly outnumbered, the Minke whale calf had little chance of survival. Here we see a large male biting down on the submerged calf.

And the resulting wound.

Wounded and exhausted the Minke calf makes one last attempt to breathe.
Before succumbing to the inevitable.

It was our great luck to have two NOAA whale biologists on board - Dr. John Durban & Dr. Holly Fearnbach. With a cross bow delivery system, they tag these Killer Whale populations with satellite transmitters enabling a wealth of data to be collected concerning the behaviors and locations of these magnificent creatures. Note the satellite tag attached to the end of the arrow.


With each tag costing several thousand dollars, Dr. Durban must wait for the perfect shot in order that the tag stick firmly within the dorsal fin. This ensures that it will stay fixed and transmitting for 3-4 months.

As John waits for his moment to fire, we witness the true size of this male. That dorsal fin can reach six vertical feet. Killer Whales this size are not found anywhere else in the world.


Successfully tagging several Killer Whales this day, John & Holly are now tracking their movements and YOU CAN TOO!!!

CLICK HERE to go to NOAA's website to track these Killer Whales.

In the right hand column, click on the drop down menu for WHALES and select Dec 4 as the date to track these specific Killer Whales. A very unique opportunity to follow along - too cool not to share!
