Orcas are one of the most successful species in the sea , prevail at the top of the solid food chain in every ocean . And one of the cause they are so successful is simple : they ’re really , really clever .
Orcas ( Orcinus orca)have rich and distinct social life sentence and have learn a singular variety of hunting strategy to take down everything from blue whales togreat clean shark . Here are 10 examples oforcaintelligence that prove killer whale are killer chic .

They get caught up in fads
Orcas are social assimilator and at times get caught up in fads — a impermanent conduct started by one or two individuals , adopted by others and then fleetly abandoned . For example , a population in the Pacific run through a phase of don salmon as hats in the 1980s . The trend started when a distaff killer whale began carrying around numb salmon on her head , and in the weeks that conform to , the behavior spread to two other pod in the same community .
Researchers spotted the salmon - wearing orcas doing the same deportment the following year and then never picture them pack Pisces on their head again , according to a 2004 follow-up of nonhuman cultivation published in the journalBiological Conservation . Recentorca attacks on boatsin Europe may be another case of a killer whale fad .

They engage in “greeting ceremonies”
Killer whale have refine societal rituals and even engage in what research worker call " greeting ceremonies . " These interactions are the orca equivalent of a mosh pit , with orcas line up in two rows and then tumbling together , Smithsonian Magazinereported . During one such event , the greeting coincided with a birth . Three orca pods reunited in the Strait of Juan de Fuca on the boundary between the U.S. and Canada in 2020 , and as the orcas whistled and snap to each other , a pregnant female produced a calf , KUOW , Seattle ’s National Public Radio news station , reported . The orcas were n’t forage and appeared to be there just to socialise on the day of the birth .
They have distinct dialects
Orcas live in pods based around related mothers and their descendants . Each fuel pod has its own typical birdcall , like different idiom of the same language . The metal money can read to mimic raw sounds , which may help them form these dialects .
Researchers taught a absorbed femaleorca called Wikie to mime human wordslike " hello " and " bye - bye , " as well as the calls of some other animals . Wikie study quickly and could reproduce some new sound on her first endeavour .
They employ specialized hunting strategies
Orcas learn highly specialized hunt strategies and pass that noesis to their offspring . Some Orcinus orca whales in Argentina beach themselves to snatch up seal on the shore , while in Antarctica , other populations create Wave to push seals off floating ocean ice .
And it ’s not just seal they learn unequalled scheme for ; killer whales are salmon specialists in portion of the Pacific , beaked whale hunter off Australia and sting - ray snatcher off New Zealand , according to the International Union for Conservation of Nature ’s ( IUCN)Red List .

They’re picky eaters
Some orca population seem to have learned that shark liver are particularly plentiful in nutrients and that it ’s deserving killing sharks and discarding the rest of their carcasses just to get to the nourishing organs . research worker have documented killer heavyweight population targeting the livers of a variety of sharks , includingattacking bully white sharks(Carcharodon carcharias ) off South Africa andtearing open giant sharks(Rhincodon typus ) off Mexico .
They appear to have friends
A 2021 survey published in the journalProceedings of the Royal Society Bfound that orca societal bonds are comparable to those seen in primates , including humans . A killer whale interacts more with sure member of its pod , usually those of a similar eld and of the same sex .
Michael Weiss , research theatre director of the Center for Whale Research in Washington land , lead the study and spoke toScienceabout two distantly related young males that were always together during the research . " Every time you see a chemical group of whales , those two are mightily there interacting with each other , " Weiss said . " I would n’t hesitate to use the word friendly relationship here . "
They seem to grieve
In 2018 , researchers blemish a seemingly brokenheartedness - stricken female killer whale pushing her beat newborn calfskin around . The orca , named Tahlequah , pushed her lifeless calf for at least 17 twenty-four hour period , covering 1,000 miles ( 1,600 kilometers ) of ocean before she finally let go of it . TheCenter for Whale Researchdescribed it as a " tour of grief . "
Wildlife charityWhale and Dolphin Conservationnoted on its site that researchers have documented several species of heavyweight and dolphins carrying gone calves or juvenile , and these " mourning demeanour " are in all probability mutual among social , long - live mammal . scientist have historically been reluctant to practice words like " grief " for fear of send off human emotions onto animal , BBC Earthpreviously report . The motivations behind this deportment still are n’t in full understand .
They can be trained
homo have been training captive Orcinus orca for decades . At SeaWorld , for case , killer whales strike poses , splash crowds , wave their pectoral fins and broadly throw - flop around on command .
Keeping grampus whales in an unreal environment is controversial , with some experts argue that it causes stress andcontributes to disease . SeaWorld announcedit was ending its killer jailed training curriculum in 2016 , and the orcas it has now will be the last generation in its care .
They care for one another
Researchers have documented legion examples of orcas affirm their fellow pod members . For example , orcas have aid injured or deform family penis survive by catch nutrient for them , the Daily Mailpreviously reported . Killerwhale mothers also care for their Word well into adulthood , and sea wolf grannie care for their grandchild after they go through menopause ( one of a handful of species to do so ) .
A 2015 study print in the journalCurrent Biologyfound that older female also guide their seedpod members to solid food , specially during tough times when food is scarce , suggesting that orcas that no longer procreate stomach the survival chance of the fuel pod by transmit wiseness .
Their brains are big
A killer whale ’s mastermind can weigh as much as 15 Ezra Pound ( 6.8 kilograms ) and is well equipped for analyse submersed environments , theOrlando Sentinelreported in 2010 . One of the species ' most impressive intellectual tools involve echolocation . Orcas click to create sound wave and locate quarry by detecting when those waves bounce off something . researcher believe that southerly resident killer whale , an orca population that lives off the Pacific Northwest glide , can signalize snow eater Salmon River from other Pisces the Fishes by detecting the sizing and orientation of Salmon River swim bladder , which give off unique acoustic signatures , according to theNational Oceanic and Atmospheric Administration .

For around 1,000 year , a population of orcas off the coast of Australia hunt alongside autochthonal multitude , and later European whaler . They would hit the water to alarm human race to the whales ' presence and would sometimes tow them to their locating using a rope . In interchange , the man commit the orcas the whales ' back talk and tongues . The relationship became known as the " Law of the Tongue . " It continued until the thirties , by which sentence commercial-grade whaling had caused baleen whale broth to plump . The killer whale left , and this orca whale population is now think to be dead .
