Inkcazo yeCalderon
I-pilot whale sisilwanyana esihle xa usijonga nje. Bebeyinxalenye yeGlobicephala, bahlukaniswa ngobukhulu babo kunye nomgaqo-siseko owomeleleyo. Ngokwahlukileyo kumahlengesi amaninzi, ibunzi lawo lingqukuva, kungoko bafumana igama labo: i-pilot whale. Inkangeleko yayo eyomeleleyo ibangelwa kukutyeba kwamafutha akhusela umzimba wayo, okuyimfuneko ukuze iphile kumanzi abandayo apho ihlala khona. Zimbini iindidi eziqatshelweyo, umnenga oyi-gray pilot (Globicephala macrorhynchus) kunye ne-pilot whale emfutshane (Globicephala melas).
Zombini iintlobo ze-pilot whale zibonisa uphawu dimorphism ngokwesondo. Iinkunzi zikhulu kakhulu kunemazi, zifikelela kwiimitha ezi-6,5 ubude kwaye zinobunzima obufikelela kwiitoni ezi-4. Iimazi, kwelinye icala, azifane zibe ngaphezu kweemitha ezi-5 kwaye ubunzima bazo buphakathi kwe-1 kunye neetoni ezi-2.
Indawo yokuhlala kunye nokuhanjiswa
Ubomi obubangela umdla bomnenga oyipilot lwenzeka kwiilwandlekazi ezinkulu zehlabathi. Nangona kunjalo, uhlobo ngalunye lunokhetho oluthile malunga ne ubushushu bamanzi. Umnenga we-pilot ongwevu unobudlelwane namanzi afudumeleyo etropikhi kunye ne-subtropical, kwaye unokufumaneka kulwandlekazi lweAtlantiki, iPasifiki, kunye nolwandle lwaseIndiya. Kwelinye icala, lo mnenga uthanda amanzi abandayo akuMntla weAtlantiki nolwandle lwaseAntarctic.
Ngaphandle kokukhetha kwabo ubushushu, zombini zizilwanyana zepelagic. Bakhetha amanzi anzulu, amaxesha amaninzi amakhulu eemitha ubunzulu.
Ukutya kunye nokutya
Ngexesha lokutya, iminenga eyi-pilot ngabazingeli abasebenzisa amathuba. Iminenga eyi-pilot itya kakhulu intlanzi kunye neskwidi, nangona zikwatya iingwane kunye nezinye izilwanyana ezingenamqolo.
Baziwa ngokusebenzisa iindlela ezahlukeneyo zokuzingela. Amanye amaqela antywila emajukujukwini ukuze akhangele amaxhoba, ngoxa amanye eleqa yaye ekoneni izikolo zentlanzi phezu komhlaba. Ngelixa ezingelayo, iminenga eyi-pilot inokusebenza kunye ukuze ibambe ixhoba layo.
Ukuziphatha kweNtlalo kunye nokuVelisa
Umnenga oyipilot waziwa ngokuziphatha kwawo ekuhlaleni. Bahlala kumaqela eentsapho ezintsonkothileyo. Amalungu eqela ayancedana ekukhuliseni abancinci, ekukhuseleni kwizisongelo, kunye nobuchule bokuzingela. I amaqela eminenga yokulinga Zinokubandakanya abantu abali-10 ukuya kwangama-50, kodwa iipods ezinkulu zinokuqulatha amawaka abantu.
Ngokuphathelele ukuzala, iminenga eyi-pilot zizilwanyana zesithembu. Indoda eyongamileyo iya kukhwelana neemazi ezininzi kwiqela layo. Emva kwexesha lokumitha elimalunga neenyanga ezili-15, iimazi zizala ithole elinye, elithi lityiswe kwaye linyanyekelwe ngunina kunye namanye amalungu eqela.
Izoyikiso kunye noLondolozo
Phezu kwabo nje ubomi obubangel’ umdla, le minenga ijamelene nezisongelo ezininzi. Esona sisongelo kwaba bazingeli abanganelisekiyo Ungcoliseko lwaselwandle, nto leyo esongela indawo yawo yokuhlala nokutya kwawo. Kweminye imimandla, iminenga eyi-pilot nayo ixhomekeke ekuzingeleni ukuphila, nto leyo ebeka isoyikiso esongezelelweyo.
Ngokubhekiselele kulondolozo, kukho imfuneko ebalulekileyo yokwandisa ulwazi loluntu kunye nomthetho wokukhusela ezi zilwanyana zibalaseleyo. Ukukhusela indawo abahlala kuyo yeyona nto iphambili ekugcineni iminenga engumlinge esempilweni kwiilwandle zethu.
