For the first time, scientists have captured video evidence of orcas cooperatively hunting whale sharks, the largest species of fish on Earth. This graphic footage proves that whale sharks are a regular part of some orcas’ diets, and solves the mystery of how they are able to kill the massive fish.

The method of hunting may imply that some orcas in the Gulf of California have acquired a special set of skills–like going after the ventral side of young whale sharks–that help them prey on these enormous fish. Orcas may have learned to do the same thing in other parts of the world, but evidence is limited, according to the team.

Orcas in the Gulf of California hunt whale sharks using advanced techniques. This highlights the need for conservation efforts.

Marine biologists documented the never-before-confirmed behavior among orcas living in the Southern Gulf of California.

Orca pods have learned to hunt whale sharks, study shows Marine biologist Austin Gallagher discusses a new study that orcas have learned to hunt whale sharks and other shark species and explains their techniques.

A pod of killer whales has developed "unique" skills to hunt the world’s biggest fish. The orcas have been spotted in the Gulf of California hunting whale sharks - which grow up to 18 meters (59 ft) long - in "coordinated" attacks.

Known to travel in groups or pods, killer whales can sabotage their victims by encircling them en masse before they attack
