Idumela lomkhomo obulalayo njengomuntu odla ulwandle olomele igazi lisetshenziswa ngobuciko yibhayisikobho. Uma ubuka i-movie yolwandle, namaqhawe asesimweni esinzima - linda izilo ezimbi ezintantayo. Ngokuqinisekile bazohlasela, futhi lonke uzungu luyovele lusebenzise ukusetshenziswa komkhiqizo othi "killer whale". Ngabe konke kunje ngempela noma kunemibono eminingi?
Indaba yethu ngomkhoma obulalayo izofana nokuqeda izinganekwane. Okokuqala, inganekwane yokuqala igama. Ekuqaleni, lesi silwane sibiza ngokungafanele ngokuthi "Asatka", kulungile ukusho - "KOsatka". Waqanjwa kanjalo ngenxa yesiphetho sesidumbu sabesilisa, esibukeka njengoluko olubukhali esimweni salo.
Ngaphezu kwalokho, kusukela ezikhathini zasendulo, lesi silwane sizitholele udumo ngomzingeli ongenasihe "ogawula izisulu." Ngokuzayo, ngasizathu simbe, ngokuya baqala ukumbiza nge-Asatka. Kuzichazamazwi, zombili izinketho zirekhodwa ngokulingana, futhi ososayensi baphikisana isikhathi eside, kepha abafikanga embonweni, ngenxa yalokho, nabo bamukela womabili amagama.
Ngakho-ke, ungathola womabili amagama emithonjeni ehlukene, kahle, ukuze ungadideki, sizowabiza ngohlamvu "A". Inganekwane yesibili. Lesi silwane sibizwa ngokuthi "umkhomo obulala umkhomo". Okokuqala udinga ukuthola - I-killer whale whale noma ihlengethwa? Akayena umkhomo, yize engowokuhlelwa kwama-cetaceans. Futhi impela akusilo ushaka, yize kukhona isiphetho esisabekayo se-dorsal fin.
I-heroine yethu iyinhlengethwa enkulu kunazo zonke ezidla inyama. Ngokuqondile, kuyisilwane esincelisayo sasemanzini se-suborder yemikhomo enamazinyo yomndeni wamahlengethwa. Ngaphambi kokuqhubeka nokuphikisa izinganekwane mayelana nomkhomo obulalayo, udinga ukumazi kangcono.
Incazelo nezici
Lapho lesi sidlakela esingaphansi kwamanzi sibhukuda siseduze kobuso bamanzi, futhi umphetho waso ngemuva ukhuphuka cishe amamitha amabili ngaphezu kogu lolwandle, kuyacaca ukuthi lokhu ukubhukuda kwabesilisa. Abesilisa bakhulu kunabesifazane, futhi bafinyelela ku-9-10 m ubude ngesisindo samathani ayi-7.5-8. Kwabesifazane, i-fin icishe ibe isigamu ubude futhi igobile. Isilinganiso sobude besifazane singu-7-8 m, isisindo singamathani ayi-4.5.
Inhloko yesilwane esincelisayo incane, inebunzi eliphansi, ngaphandle kwe "dolomo" lehlengethwa. Amehlo mancane futhi. Amazinyo makhulu futhi abukhali, afinyelela ku-13 cm ubude, ngawo ahlukanisa kalula inyamazane enkulu. Amaphiko esifuba - ama-60 cm ubude no-15 cm ububanzi, hhayi akhonjisiwe, kepha abanzi, asondele esilinganisweni se-oval.
Umbala usebenza kahle kakhulu, omunye angase athi - "i-tailcoat pair". Isikhumba se-satin ngemuva nasezinhlangothini ikakhulu simnyama ngejet, kanti isisu simhlophe qwa. Eminye imikhomo yokubulala yase-Antarctic inecala elikhanya kancane kunangemuva. Kukhona indawo empunga ngemuva ngemuva kwephiko, elifana nesimo sesali.
Ezinhlangothini, kunezindawo ezimhlophe zokulungiswa nobukhulu obuhlukahlukene kuyo yonke indawo, kunezindawo ezinjalo ngaphansi kwamehlo. Ukuma kwawo wonke amabala asemzimbeni womkhomo obulalayo kukodwa, kungasetshenziswa ukukhomba isilwane, njengomuntu ngeminwe.
Ngendlela, izindawo ezimhlophe njengeqhwa emzimbeni wesilwane esincelisayo kwezinye izindawo zingaba luhlaza okotshani noma kuphuzi ngenxa yento ebalabala. Kwesinye isikhathi kuba nabantu abamnyama ngokuphelele - ama-melanists, noma abamhlophe ngokuphelele - ama-albino.
Yenza umbono ohlala njalo umkhomo obulala umkhomo esithombeni... Akusona isizathu ukuthi siphinde sakhuluma ngomkhomo lapha, ngoba kwezinye izithombe kubonakala ngokusobala ukuthi isilwane sasolwandle esihle ngokungajwayelekile, esihle futhi esikhulu "sivumela" kanjani umthombo omncane wamanzi. Njengoba nje imikhomo ikwenza.
Izinhlobo
Ezinye izibonelo ezi-2 zingabangelwa uhlobo lwemikhomo ebulalayo:
- Mnyama umbulali whale, noma incane, ibizwa nangokuthi amanga ngoba umbala wayo omnyama ngokuphelele. Iphansi kunaleyo ejwayelekile ngosayizi, njengoba ikhula ifike kumamitha ayi-6 ubude futhi inesisindo cishe sethani - eyodwa nohhafu. Ungu-thermophilic kakhulu kunesihlobo sakhe, futhi wakhetha amanzi endawo enesimo sezulu esishisayo kanye ne-subtropics yokuhlala.
- UPhereza uyinkonyane encane ebulalayo. Ukhule wafika kumamitha amabili kuphela, udla izinhlanzi ezincane futhi uzama ukungabonwa ngabantu. Ipendiwe ngokumpunga okumnyama.
Cishe iminyaka engu-6-7 kwavela umlingisi othakazelisayo ku-Intanethi umbulali whale okuthiwa i-Iceberg. Sikwazile ukuyishutha kabili eduze kwaseCommander Islands. Le vidiyo ibiphelezelwa yi-arya yokuthi kusuka ngo-2008 kuya ku-2015, kwabonakala imikhomo emihlanu enjalo engxenyeni yaseRussia ePacific Ocean. Kodwa-ke, sekutholakele ukuthi lolu akusilo uhlobo olusha lwesilwane, kepha yi-albino. Kungenzeka, umbala omhlophe ube yinkomba ethusayo yendawo engafanelekile.
Indlela yokuphila kanye nendawo yokuhlala
Umkhomo obulalayo utholakala ebuningini boLwandle Lomhlaba, kusukela ezindaweni ezishisayo kuye ezifundeni ezibandayo. Igijima olwandle olungapheli ukusuka e-Antarctica kuya eCanada naseKamchatka, futhi kusuka eNorway kuya endaweni eyeqisayo yeNingizimu Melika. Ikakhulukazi la mahlengethwa amahle futhi ayingozi athandana namanzi asenyakatho yePacific, eningizimu yoLwandle iBering, kanye nensimu engasogwini lweIziqhingi zase-Aleutian nase-Alaska.
Kusukela olwandle, bakhethe futhi oBarents noMhlophe. Awuvamile ukubabona eMedithera. Futhi awatholakali nhlobo oLwandle i-Laptev, kanye naseLwandle Olumnyama, i-Azov naseMpumalanga yeSiberia. ERussia, i-killer whale ihlala eduze ne-Commander Islands kanye nasedeni leKuril. Ikhetha izindawo lapho ulwandle lupholile khona, ngakho-ke ayihlali ezindaweni ezishisayo isikhathi eside.
Ngemuva kocwaningo olude, odokotela be-ichthyologists bahlukanisa la makhosi olwandle ngamaqembu amabili: "abahlali", okungukuthi, izakhamuzi zaphakade zesifunda esithile; futhi "okwesikhashana" noma "ukuhamba", lezo ezihamba ngobukhulu bolwandle. Kusekhona izidliva zokubhukuda mahhala, kepha azifundiswanga kangako, akucaci ukuthi zibhukuda kuphi, zidlani, ngakho-ke ngeke sikhulume ngazo.
"Abahlali" bakha imindeni ephelele, bakha imibhangqwana eshadile engahlukani amashumi eminyaka. Bahlala ezindaweni ezinomkhawulo. Isakhiwo senhlalo sisuselwa kwimatriarchy. Insikazi enamathole abo bobabili ubulili yakha iqembu elilodwa.
Leli qembu lifaka cishe abantu abayi-15. Imikhomo yokubulala ihlakaniphe kakhulu, inemithetho yayo yezenhlalo, iqembu ngalinye linolimi lwalo. Le mikhomo ebulalayo ibhekwa njengokuthula kakhulu, ngomqondo ongokomfanekiso. Imikhomo yokubulala i- “Transit” ayifundwa kangako, amaphesenti ayo mancane kakhulu kunalawo angomphela.
Baqaphele kakhulu, bahamba cishe bathule, banikezwe igama elithi "abazingeli abathule", abakwazi ukubona futhi kunzima ukulandela umkhondo. Zizwa ngemvamisa efanayo nemikhomo futhi zenza imisindo efana naleyo, ngakho-ke azikhulumi ngesikhathi sokuzingela ukuze zingasabisi inyamazane. Uma bebona "umhlali", bavumela indlela ukuze bangangqubuzani.
Ukuhlaziywa kwe-DNA kukhombisile ukuthi la maqembu awazange ahlangane izinkulungwane eziningi zeminyaka. Ngakho-ke, kancane kancane baqala ukwehluka omunye komunye, yize kungenjalo kakhulu. Isibonelo, amaphiko azo omgogodla anezimo ezihlukile. Lawa maqembu futhi anezintandokazi ezahlukahlukene zokunambitha, ngaphezu kwalokho, akhuluma "izilimi" ezihlukile, okungukuthi, anikeza amasiginali womsindo ahlukile.
Ukudla okunomsoco
Yiqiniso, abaningi bayakuthakasela lokho killer imikhomo udle? Lezi zilwane zinemibono ehlukene yokudla okunempilo. Isakhamuzi ngasinye sinokuncanyelwa okuncane. Olwandle lwaseNorway, bayakujabulela ukubamba i-herring edumile, kuthi njalo ekwindla bathuthelezele lona eduze nogu.
Eduze kwabo, abanye abazingeli bagxile kuma-pinnipeds. Uma, ukuze kube lula, sivumelene ngokuhlukanisa imikhomo ebulala izinhlobo ezimbili - "abahlali nezokuthutha", kufanele futhi sibahlukanise ngokuya ngokudla abakuthandayo. Abokuqala badla izinhlanzi, abokugcina badla inyama.
"Izakhamizi" zigxile ku-shellfish nezinhlanzi, zikhetha ukuzingela okuncane kakhulu. Bafola ngohlu lwamaketanga bese bekama ulwandle oluvulekile befuna izikole zezinhlanzi, ngenkathi behlala bexhumana njalo besebenzisa i-echolocation. Sebetholile ijoyinti, balizungeza neqembu lonke bese "belishaya" lifike ebholeni, bese "bengena" kulo, bethola inyamazane yabo.
Kepha "imikhomo yokubulala ezokuthutha" - yizona nje izidlakela ezinonya ezinonya. Ukuzingela kwabo kufana "nemashi" emangazayo eyenzelwe ukubamba ukudla okumnandi kakhulu futhi okunomsoco. Imvamisa, izimvu zamanzi ezimnyama nezimpawu zasenyakatho ezinamalebe, ezaziwa ngathi njenge amabhubesi olwandle, noma I-Steller's enyakatho amabhubesi olwandle (oqanjwe ngegama likadokotela uGeorg Steller, owahamba nohambo ngaphansi komyalo kaBering futhi waba ngowokuqala ukuchaza lezi zilwane).
Imikhomo ebulalayo iphuma iyozingela uphawu olujwayelekile kumathathu noma amane, ishayele isisulu bese iyivala ngemisila enamandla. Emabhubesini akwaSteller, bazozingela kakade abahlanu noma abayisithupha babo. Bangaphishekela inyamazane kuze kube ngamahora angu-2-3, kepha basazuza umphumela oyifunayo - ngemuva kokushaywa okunamandla, bacwilisa isisulu ngemisila yabo.
"Igenge" ephelele selivele lihlangana ngemikhomo emikhulu. Ababulali bazungeze le colossus bese beqala ukumqeda amandla, kumenze azizwe engazweli. Kuchazwe icala: ngasogwini lwaseCalifornia, imikhomo engamashumi amathathu ebulala izungeze i-whale eluhlaza okwesibhakabhaka engamamitha angama-20 yase iyayihlaba.
Omunye wamshaya ekhanda ngomsila ekhanda, abanye bazama ukumshaya ezinhlangothini, abanye bagxuma emhlane noma bacwila besezansi. Ukuhlaselwa kokuphanga okuhlelekile. Ekugcineni, baqala ukuklebhula inyama yakhe. Kwakuyingozi futhi kungenangqondo ukugxambukela kule nqubo. Akunakwenzeka ukumisa imikhomo yokubulala ngenkathi uzingela.
Amabhubesi olwandle, njengoba kutholakele izazi ze-ichthyologists zaseCanada, zehle kakhulu ngenani emashumini eminyaka amuva nje. Uma ngeminyaka yama-80s yekhulu elidlule bekukhona izinkulungwane ezingamakhulu amaningana, manje cishe azizinkulungwane ezingamashumi amathathu. Akukho okuxakile, muva nje lapho abantu bememezele ukumiswa ekuzingeleni kwabo. Kepha imikhomo ebulalayo ayikwazi lokhu.
Inyama yalezi zilwane inamanzi amaningi futhi ithambile, kuningi kwayo, isampuli ngayinye inesisindo esifinyelela kutani. Izilwane eziyizinyamazana zazithanda ukunambitheka kwezingonyama zasolwandle futhi zehlisa kakhulu inani lazo labantu. Kodwa-ke, ngaphezu kwezimpawu nezingonyama zasolwandle, kunezinye izinto zokudoba imikhomo ezibulalayo.
Esiswini sabadli bezilwane ababanjiwe, izinsalela zezimfudu zasolwandle, ama-penguin, amabhere asezindaweni ezibandayo ngisho nokudla, okwamangaza umzingeli wamanzi, kwatholakala - i-moose! Kodwa-ke, ngaphandle kokudla okunje, abazingeli kwesinye isikhathi baziveza njengama-gourmets futhi bathanda ukuzitika ngama-otter asolwandle, noma ngenye indlela ama-sea otters.
Siyazazi lezi zilwane njengama-beavers olwandle namaKamchatka. Zimbozwe ngoboya obukhulu, kuphela lokhu akonakalisi isifiso semikhomo ebulalayo. I-otter yasolwandle inesisindo esingu-16-40 kg, kulula kakhulu futhi icwecwe ukugwinya konke. Ukuze ithole okwanele, idinga ukudla cishe izilwane eziyi-7 nsuku zonke.
Isilwane esisodwa somkhomo esibulalayo ngonyaka sikwazi ukugwinya cishe lezi zilwane zasolwandle ezingama-2000, uma sizizingela nsuku zonke. Ngenxa yalokhu, inani lama-otter asolwandle nalo lehle kakhulu eminyakeni engaphezu kwamashumi amathathu, yize ukuzingelwa kwawo kulinganiselwe.
Ukuzala kanye nesikhathi sokuphila
Izibopho zomndeni ngaphakathi kweqembu elifanayo zivimbela lezi ziqhwaga ekuhlanganiseni ngaphakathi kwepakethe. Ngakho-ke, abantu bemindeni ehlukene bangena emshadweni. Ukuthomba kuza eminyakeni eyi-12-14. Isikhathi sokuzalela siqala ehlobo futhi ngaso sonke isikhathi sihambisana nomdanso omuhle.
"Umnumzane onamandla" ngokoqobo "uzungeze" intombi yakhe ngokunaka, ibhukuda eduze kwayo. Uyamthinta ngazo zonke izingxenye zomzimba wakhe - amaphiko, ikhala, umsila, okwenza lokhu kunyakaza kube mnene ngendlela engachazeki nangokuthinta. Kwenzeka ukuthi isoka linikeza okhethiweyo walo njengezikhumbuzo - izinto ezahlukahlukene ezivela olwandle, amakhorali noma amagobolondo.
Ngaphezu kwalokho, owesifazane angagcina lezi zipho isikhathi eside. Ekugcineni, konke kwahlala esikhathini esedlule - womabili amahora wokuqomisana, futhi nokuxabana okunomona namanye amadoda, inqubo yokukhwelana "isisu nesisu" yenzeka, futhi manje umama okhulelwe uqala inqubo ende yokukhulelwa. Kuthatha izinyanga eziyi-16-18.
Ngalesi sikhathi, wonke umhlambi uyamnakekela futhi umvikele. "Ingane" isivele izalwe ngosayizi ohloniphekile, cishe u-2.5-2.7 m. Ngemuva kokuthi ingane "iwele" emanzini, "u-retinue" ushiya umama kanye ne-cub yedwa, ebanikeza ithuba lokuxhumana ngasese. Ihlengethwa elincane ekuqaleni lizulazula lingenakuzisiza emanzini, kodwa-ke umzali uyalisiza.
Uyamphusha ngamakhala ebusweni bamanzi ukuze adonse umoya, namaphaphu akhe asebenze. Insikazi izala cishe kanye eminyakeni emihlanu. Ngesikhathi sokuphila kwakhe, angazala "iris" ezi-6-7. Cishe iminyaka engama-40-50, le "ntokazi" ingena ocansini, ayisakwazi ukubeletha, futhi ingena esigabeni se- "matron".
Ama-killer whales nama-grindas (amahlengethwa amnyama) ukuphela kwezinhlobo zezilwane, ezifana nabantu, ezihlangabezana nokuguga phakathi kwezihlobo zazo. Futhi esimeni senhlonipho enkulu. Badlula esikhathini sokuya esikhathini bese beqhubeka nokuphila nokuzingela iminyaka engaphezu kweshumi nambili.
"Abesilisa" baphila kuze kube yiminyaka engama-50 ubudala, futhi "abesifazane asebekhulile" baphila kuze kufike ku-75-80, ngisho kuze kube yiminyaka eyi-100. Ekuthunjweni, lezi zikhathi zincishiswa ngesigamu noma kathathu. Akukaze, ngaphansi kwanoma yiziphi izimo, "abahlali" bahlangane nabantu "bokuhamba". Lesi esinye isibonakaliso sokuzihlukanisa ngamaqembu ahlukene.
Kungani umkhoma obulalayo ubizwa ngokuthi i-killer whale?
Ukuthola kungani killer whale killer whale, udinga ukuzicwilisa emlandweni. Ngekhulu le-18 leli dolphin elikhulu labizwa ngabaseSpain ngokuthi "umbulali wemikhomo" - "asesina ballenas", kanye nabaseBrithani abahumusha kabi besuselwa eSpain beya olimini lwabo, kwavela ukuthi "killer whale" - "killer whale". Yile ndlela esathola ngayo inganekwane yesithathu. Eqinisweni, isimo sawo sehlukile, njengathi nje. Banama "couch amazambane" abo kanye nama "vagabonds" abo.
I- "Homebodies" iyikhwalithi ezuzwe kwimikhomo yokubulala "yabahlali". Abakuthandi ukudla izidalwa ezinegazi elifudumele futhi abakhombisi ulaka kubantu nakwezinye izilwane ezincelisayo.
"AmaTramp" ayisici esiseduze nemikhomo yokubulala "yokuhamba". Cishe, udumo olwesabekayo lwabahamba njengababulali. Hhayi ngoba belungele ukubulala noma yisiphi isidalwa olwandle. Okokuqala, babizwa kanjalo ngoba bona, njengabaphangi bangempela, babulala izisulu eziningi kakhulu kunalokho abangakudla. Uma bebulale umkhoma, futhi bengakwazi ukudla isidumbu sonke ngasikhathi sinye, badla kuphela izingxenye ezithile zomzimba, lezo ezinambitheka futhi ezithambile (ulimi, izindebe, njll.).
Ekujuleni kolwandle, imikhomo ebulalayo ayinabaphikisi abafanelekile. Ngisho noshaka omhlophe owesabekayo nonolaka akayona imbangi yakhe, kodwa uyisisulu. Kuzwakala kungenangqondo, kodwa kuyiqiniso: umhlaseli omubi owesabekayo unesitha esisodwa - ihlengethwa elibizwa ngokuthi i-whale dolphin.
Njalo ngonyaka, ososayensi bathola umkhondo wamazinyo akhe emzimbeni wezilwane ezahlukahlukene, futhi abaningi bahlupheke ngaphezu kwesisodwa. Ingaphezu kwengxenye eyodwa kwezintathu yemikhomo yama-humpback, futhi ngayinye yazo ilingana ngesisindo nezindlovu eziyishumi, zathola izibazi-amamaki avela emazinyweni ezilwane ezidlayo.
Futhi imihlambi yemikhomo empunga efudukayo nemikhomo yama-minke whales (minke whales) isengozini engapheli ngenxa yokuhlaselwa komzingeli ongenasihawu, futhi ukuphela kwayo kuvame ukudabukisa, njengoba kufakazelwa amathambo ezilwane atholakala ogwini.
Ukuthanda kwakhe igazi kwaqashelwa ngabantu basendulo. Izilwane eziningi zasolwandle, ngisho nemikhomo ehlobene eduze ye-beluga, ihlupheka kakhulu ngomkhomo obulalayo. Akudingeki ukuthi kuthiwe, uma isigebenga njengekhanda lomnsalo sibaleka ngokuhlazisayo kuye, kwesinye isikhathi sidumaza ababethi bemikhomo abaphuma baya kozingela.
Okuwukuphela kwesitha somkhomo obulalayo uqobo ngumuntu. Vele, ukudoba ngezinga lezimboni kwavinjelwa kubo ngo-1982. Kepha lokhu akusebenzi kubantu bomdabu, nokuzingela kwabo imikhomo ebulalayo, kanye nokubanjwa kwezinhloso zesayensi.
Kepha nakhu okwenzekile ngemuva kokubuka nokutadisha indlela yokuziphatha kwalezi zilwane - i-killer whale inelukuluku lokwazi, kepha endaweni yemvelo, umuntu akamcasuli, futhi bekungekho zimo zokuhlaselwa komuntu olwandle. Ngakho-ke inganekwane yesine yokuthi uyisilo esesabekayo, "ukufa maphakathi nolwandle", seyilahlekile. Uhlasela kuphela ukudla. Akujwayelekile ukuthi abulale ezinye izilwane kanjalo nje.
Ekuthunjweni, angabonisa ukuhlukunyezwa, kodwa kuphela uma elambile noma elimele. Kumahlengethwa agcinwa anezimpawu zasolwandle namahlengethwa endaweni eyodwa futhi aqeqeshwe ndawonye. Ngasikhathi sinye, bondla ukusutha kwabo. Kuze kube manje, azikho izindaba ezisabekayo ezirekhodwe ngokusemthethweni. Kwakunamahlebezi okuhlaselwa komqeqeshi, kepha akekho owanikeza imininingwane yendaba.
Amaqiniso Athandekayo
- Imikhomo ebulalayo inesimo senhlalo esondelene "nogogo" wethu.Abesifazane asebekhulile, abangasakwazi ukuzala inzalo, bakhulisa izingane, bazifundise ukuhlakanipha kwempilo: banquma izisekelo zamasu wokuzingela, imizila yokufuduka, nendawo ye-fairway ezinhlokweni zentsha. Yebo, izinto eziningi zidinga ukukwazi "ukutshela" abasha, ngenkathi isizukulwane esiphakathi sisazingelwa.
- Umkhomo obulalayo ubhekwa njengesinye sezidalwa ezinesihawu kakhulu. Akukona nje kuphela ukuthi abasha banakekela asebekhulile, basiza abagulayo nabalimele, baphinde bahlukanise inyamazane elethelwa iqembu lonke. Lokho, okuncane, kepha kufanele kwanele wonke umuntu!
- Ngaphambi kokungena endaweni engaziwa ukuzingela, killer whale "sonate" it, enze i-sonar ultrasound. Kumele baqonde ukuthi ngabe imizimba yabo emikhulu izokwazi yini ukusuka ngasogwini olungaziwa.
- Ekuzingeleni banobuchule obukhulu, banendlela yabo yokuhlukumeza umuntu ngamunye. Kumuntu "ungagijima" isikhathi eside ngaphesheya kolwandle, ngokusobala ukujabulela ukuhamba, futhi kungcono ukuhlasela umuntu "onenqama". Eminyakeni eyizigidi edlule, lezi zilwane ziye zaqinisa ugebhezi kangangokuthi zingakwazi ukukhokhela indlela enjalo. Kuyamangaza ukuthi ngokomzimba baqagela ngokunembile iphuzu elibuthakathaka leshwa - izigaxa, ikhanda noma isisu.
- Kuyathakazelisa ukuthi kukhona nenhlanzi ebizwa nge- "killer whale" yomndeni we-orca we-catfish oda. Ibizwa futhi ngokuthi "iyancinza" ngenxa yokuthi uma ibanjwa emanzini, yenza imisindo ephezulu yokuncinza.
