great white shark has the most formidable foe. The electronic tag data found that white sharks flee their feeding areas when orcas are present and do not return until the following season."When confronted by orcas, white sharks will immediately vacate their preferred hunting ground and will not return for up to a year, even though the orcas are only passing through," said Dr.
But in the great showdown between shark and orca, who benefits? An unlikely background character, the elephant seals!Elephant seal colonies in the Farallones were shown to indirectly benefit from the interactions between these two top predators. Great white sharks gather at the Farallones every year between September and December to hunt young elephant seals. Past data has shown that they typically spend more than a month circling this region.
To give you an idea of how ginormous the data sources that Tietz mentions are, here's the breakdown: the group is using data from 165 white sharks tagged between 2006 and 2013, and compiled 27 years of seal, orca and shark surveys at the Farallones. To determine when the dueling predators co-occurred in the region, researchers compared data from the electronic shark tags with field observations of orca sightings.
Great article! I wonder if the data from South African White Shark population mirrors that of Californian White Sharks.
I'm a mammal, so I've got to get behind the mammals: Orcas, baby, Orcas!
Well orcas hunt in family groups , great whites are generally loners. Give it to the orcas JustSayin Sharks Killerwhales

Obviously orcas aka killer whales
I’ll be honest haven’t read the article but saw a shark week thing on this and was surprised but also like wtf? How ..it was weird bc great whites are super fast and strong I’m still like “maybe the marine biologists are confused about all this”..seriously doubt that..just odd
