An orca was seen balancing a salmon on its head in coastal waters in Washington state. Orcas were previously observed doing the same thing in the 1980s. It’s not clear what the behavior means ...
Orcas also prey on larger species such as sperm whales, grey whales, humpback whales and minke whales. [ 84 ] [ 40 ] On three separate occasions in 2019 orcas were recorded to have killed blue whales off the south coast of Western Australia, including an estimated 18–22-meter (59–72 ft) individual.

The research vessel Noctiluca of the Northwest Fisheries Science Center in close proximity to an orca. The southern resident orcas, also known as the southern resident killer whales (SRKW), are the smallest of four communities of the exclusively fish-eating ecotype of orca in the northeast Pacific Ocean.
Killer whales have no predators -- except for humans. Documentaries like 'Blackfish' reveal the exploitation behind whale captivity. In the late 1960's, Famous orca Shamu was the whale who set the ...
Attacks on large whales in the region are relatively rare and no incidents of successful predation have occurred, although isolated incidents of transients harassing gray whales and humpback whales, including predation, have been observed outside the Salish Sea. However, interactions do sometimes become spectacular; in October 2022, a rare ...
It has also been observed in larger cetaceans such as false killer whales and orca, [20] [21] although most larger Odontocetes do not seek out any form of interaction with boats. Bow-riding is the most common form of interactive behaviour with boats across a variety of smaller Odontocete species, such as dolphins in the genera Stenella and ...
Orcas in the Gulf of California appear to have gained special skills to hunt and kill the world’s largest fish, according to a new study.. Whale sharks, which grow up to 18m long, are known to ...
