Spectacular brand-new video footage records the minute adult whale thoroughly teach their calves how to hunt, showing how to press a seal a little bit of ice before getting the young to try themselves.

The clip reveals a group of 7 whales– 4 grownups and 3 calves– as they circle a seal on a small portion of ice in western Antarctica’s Marguerite Bay. The lesson, which lasted over an hour, was recorded for the brand-new PBS program “Nature: Expedition Killer Whale,” which follows an impressive group of pack ice whale (Orcinus whalethat live off the coast of Antarctica.

“The biggest surprise was the careful, measured way in which the females kept the seal corralled close to the piece of ice without fatally injuring it, so that it would climb back out onto the ice,” Leigh Hickmotta whale biologist and science consultant for the program, who observed the encounter from a boat close by, informed Live Science in an e-mail.

“This allowed the females to show the calves a number of different approaches to gain access to the seal, all in one teaching session,” he stated. The searching methods they taught the calves consisted of “wave washing, tipping the ice, bubble blowing to flush the seal from under the ice and taking hold of the seal by its hind flippers to prevent injury from its teeth.”

In the video footage, a female whale leads the lesson, showing how to pull the seal the ice by its tail, as the calves see and find out. She lets the seal escape, and after it leaps back on the ice, the calves take turns practicing the method– a habits that’s duplicated over and over.

Orcas are extremely smart peak predators. They are social, residing in household pods, and hunt in packs. They’re amongst the couple of types understood to actively teach their young (and one another) various abilities, which can lead to ingenious brand-new habits
