## Natural History & Behavior
### The Lowdown
The orca (*Orcinus orca*) is the largest member of the dolphin family and the ocean's apex predator, with no natural predators once grown, though young orcas may be attacked by other killer whales or large sharks. Orcas rely on underwater sound to feed, communicate, and navigate. The Southern Residents, a fish-eating population in the eastern Pacific, hunt by echolocation, clicking out sound and reading the echoes so precisely that they can tell one salmon species from another. Echolocation lets killer whales detect fish up to 500 feet away, much farther than they could see in dark water. Each pod also has its own dialect of calls, learned and culturally passed on between whales, and one study puts the average detection range of resident orcas' long-range calls at 10 to 16 kilometers, about 6 to 10 miles, in a calm sea.
Different ecotypes have their own learned hunting tactics. Off the Antarctic Peninsula, groups of pack ice killer whales work together to make waves that wash Weddell seals off ice floes. In one study they caught 12 of the 16 Weddell seals they attacked, and a successful attack took four waves on average. Off northern Norway, orcas use carousel feeding: they herd herring into a tight, dense ball near the surface, then slap its edge with their tail flukes to stun the fish before eating them one by one.
> **Dialects that shift** A study that recorded two resident orca families for 12 to 13 years found one of their call types changing, in a similar way in both families. Hunting skills are taught as well, passed to younger whales in the pod through apprenticeship.
Off the coast of South Africa, a killer whale has been filmed trying to roll a [great white shark](/animals/great-white-shark/) upside down, into a position that sends sharks into tonic immobility, a paralysis-like state, before biting into its abdomen just behind the pectoral fins. That matches the attack researchers had suspected from shark carcasses missing their livers, and one study estimated that the liver of an adult white shark of about 428 kilograms holds roughly as much energy as an adult male orca needs in a day. At California's Southeast Farallon Island, transient orcas killed a white shark in 1997 and ate only its liver. In 2009, orcas stayed just over two and a half hours and were not seen killing any shark, yet the island stayed virtually shark-free for the rest of that season.
## Frequently Asked Questions
### Do different orca pods have their own dialects?
Yes. Animal Diversity Web reports that each pod has its own dialect, which sounds slightly different from other pods'. NOAA Fisheries says the calls are learned, culturally transmitted between whales, and serve as family badges. *(Source: [Animal Diversity Web, University of Michigan]())*
### How big do orcas get, and how long do they live?
NOAA Fisheries puts killer whales at up to 32 feet long and up to 11 tons. In the wild, males live about 30 years on average and can reach at least 60, while females typically live about 50 years and can reach at least 90. *(Source: [NOAA Fisheries]())*
### How do orca calves learn to hunt?
In the Crozet Archipelago, researchers followed two young female orcas learning to hunt elephant seal pups by stranding themselves on the beach. They first practised the technique on their own at four to five years old and were first seen trying to catch a pup this way at five to six, when they still needed an adult female's help to get back into the water with their prey. *(Source: [Guinet & Bouvier 1995]())*
