Orcas haben gesehen, wie sie junge Weiße Haie töteten, indem sie sie auf den Kopf stellten: Wissenschaftler haben beobachtet, wie eine spezialisierte Haijagdgruppe im Golf von Kalifornien wiederholt auf junge Weiße Haie zielte, sie auf den Kopf stellte und ihre energiereichen Lebern herausnahm, um sie mit der Schule zu teilen.

I’ve linked to the press release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:

**Orcas seen killing young great white sharks by flipping them upside-down**

An adult great white shark has just one predator: the orca. Until recently, orcas have only been observed regularly preying on these sharks in South Africa, where they usually prefer to hunt larger adults, which provide more food once caught. But now **scientists have observed a specialist shark-hunting pod in the Gulf of California repeatedly targeting juvenile white sharks, flipping them upside-down and taking out their energy-rich livers to share with the pod**. They could be taking advantage of a local shark nursery to hunt younger, less experienced individuals which are easier to catch and subdue.

The scientists spotted two hunts, killing three white sharks, during routine monitoring of the orcas. They recorded the hunts in detail, identifying the individual orcas involved from features on their dorsal fins.

During the first hunt, in August 2020, five orcas were seen pursuing a juvenile white shark. They pushed it to the surface and worked together to turn it upside down. Ultimately, they took it underwater and reappeared with the shark’s liver in their mouths. Shortly afterwards, they did the same with a second juvenile shark. A second hunt, witnessed in August 2022, followed a similar pattern: five orcas pushed a juvenile white shark onto its back and up to the surface. The shark was bleeding from its gills, and its liver was visible. The orcas were seen eating it.

Turning a shark upside down like that induces a state called tonic immobility, by changing the shark’s awareness of its surroundings in a way that paralyzes it.
