“Ukuthula kunomsindo, ngakho lokho bekukubi kakhulu,” kushoUBertie Gregory, i-National Geographic Explorer kanye nomsingathi we-Animals Up Close ku-Disney+.

UGregory wayedabule iDrake Passage ehlukanisa iNingizimu Melika nezwekazi eliseningizimu kakhulu ukuze enze ifilimu eyivelakancane.i-orcainani labantu elibizwa nge-B1. Aziwa ngesu lawo eliyingqayizivele lokudala amagagasi avala izingcezu zeqhwa, lawa ma-orcas e-Antarctic ahluke ngofuzo, cishe anenani elilinganiselwa ku-100. Unodoli Wocansi Wonodoli

Ngakho-ke lapho u-Gregory nethimba lakhe labakhi bamafilimu nososayensi beqala ukulandela i-pod encane yama-B1 ukuzingela izimvula eqhweni elishayelayo, bacabanga ukuthi bazoshaya i-jackpot. Kodwa lokho ababengakwazi ngaleso sikhathi ukuthi ama-orcas ayengewodwa.

Okokuqala, i-pod yahlasela inyamazane yabo—aWeddell sealilele i-smack-dab phakathi nesiqephu esikhulu seqhwa. Udoli Wocansi Wamadoda Unodoli Owufenda

(Funda ukuthi i-orcas ingabulala kanjani isilwane esikhulu kunazo zonke emhlabeni.)

UGregory uthi: “Babhukuda ngaphansi kweqhwa, njengoba nje bevame ukwenza, kodwa asibonanga gagasi eliqhumayo, futhi ngathi, ‘Oh, kumelwe ukuba baliphazamisile. "Kodwa esikhundleni salokho babenza i-shockwave ngaphansi kwamanzi."

Ngendiza yasemoyeni, izisebenzi zabukela njengoba i-orcas ihlakaza isiteji esineqhwa ngaphansi. Yasebenza, yafaka uphawu emanzini, lapho i-pod yabe isichitha imizuzu eminingana ikhathaza isilwane.

“Khona-ke, kungazelelwe, ababiliimikhomo ye-humpbackvuka nje,” kusho uGregory. “Benza lo msindo wecilongo omangalisayo [o]mkhulu kakhulu, uzwakala esikhumbeni sesikebhe, njengendlovu ikhala.”

Ososayensi babone futhi bathwebula ama-humpback, adla ama-crustaceans amancane abizwa ngokuthi ama-krill, aphazamisa ukuzingela kwe-orca izikhathi eziningi, kodwa izikhathi ezimbalwa kuphela phakathi kwe-B1 orcas. Ngoba izilwane ezidla ezinye ngezinye izikhathi zikhomba amankonyane angama-humpback, Doll Sex Doll

imikhomo ingase icasule ama-orcas lapho iyibona izingela, kusho ochwepheshe. (Funda kabanzi:Kungani ama-humpback whale avikela ezinye izilwane emikhomoni ebulalayo.)

Kulesi sibonelo, ama-humpbacks abesephuzile kakhulu ukungenelela egameni le-seal, kodwa phakathi kokukhala kwecilongo kanye nesinqumo sokubhukuda ngqo ku-orca pod, u-Gregory ukholelwa ukuthi laba ababili bebezama ukumosha ukuzingela kwe-orca ngisho nokuvikela uphawu.

Leigh Hickmott, isazi sezinto eziphilayo zomkhomo e-University of St. Andrews eScotland kanye nomhlanganyeli kaGregory emsebenzini wokutadisha ama-B1, bayavuma.

"Ngicabanga ukuthi kukhombisa izimpawu ezicacile zokuzicabangela," kusho u-Hickmott.
