Based on experimentation involving familiar sounds of Orcas that consume fish and unfamiliar vocalizations of mammal-hunting Killer Whales, one study suggests that long-finned pilot whales can distinguish between familiar and unaccustomed types of Orca, noting behavioral differences like the ceasing of feeding when mammal-hunting Orcas' sounds ...
Killer whales are apex predators, meaning that they themselves have no natural predators. They are sometimes called the wolves of the sea, because they hunt in groups like wolf packs. Killer whales hunt varied prey including fish, cephalopods, mammals, sea birds and sea turtles.
The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, it is found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
In orcas, false killer whales, short-finned pilot whales, narwhals, and belugas, there is an unusually long post-reproductive lifespan in females. Older females, though unable to have their own children, play a key role in the rearing of other calves in the pod, and in this sense, given the costs of pregnancy especially at an advanced age ...
An orca pod in the Pacific Ocean off the coast of Mexico has devised a cunning strategy to hunt and kill whale sharks — the world’s largest fish that can grow up to 18 meters (60 feet) in ...

These orcas have a killer fashion sense. Always head of the curve, blackfish off the West Coast are bringing back a fad that hasn’t been seen in the last four decades: salmon hats. The ocean’s ...
This is the first time orcas have been documented using this precision feeding technique in this region. [11] Starboard was first filmed via drone killing a great white in May 2022 around Mossel Bay, alongside four other orcas [12] – this was the first time ever this predation has been filmed. After the attack, white sharks in the area fled ...
