Isilingo esisha sokuthola ukuthi hlobo luni lwempilo olukhona olwandle selususe ukuqagela mayelana nethemba lesilo esikhulu impela esicashe ekujuleni kolwandle. Ngushaka omkhulu noma ingwane enkulu? Noma into esabeka kakhulu ukwedlula esake sayicabanga?
Okwamanje, sihlole kuphela u-5% wolwandle lomhlaba, oluhlanganisa ama-70% womhlaba. Abantu bebelokhu behehwa izimfihlo ezisekujuleni kwamanzi.
Isivivinyo se-Great Gator
Ngenkathi ososayensi bezinto zasolwandle uCraig McClain noClifton Nunnally abavela eLouisiana Universities Marine Consortium befuna ukuthola ukuqonda okungcono ngokwenzeka olwandle, benza ucwaningo olwaziwa njenge Isivivinyo seGator Enkulu, okwaveza imiphumela ethokozisayo.
Abaphenyi bacwilisa i-buffet yezidalwa zasolwandle eziyimfihlakalo ezibandakanya ama-alligator amathathu afile, nezinsimbi eziboshelwe kubo. Babenelukuluku lokubona ukuthi izidumbu zabo zizodliwa kanjani izidalwa ezicashe olwandle.
"Ukuhlola indawo yokudla ngaphakathi olwandle, sabeka ama-alligator amathathu afile okungenani amamitha ayi-6,600 51 ezansi eGulf of Mexico izinsuku ezingama-XNUMX," kusho uClifton Nunnally waseLouisiana University.
Okulandelayo kwashaqisa impela
I-gator yokuqala idliwe kungakapheli amahora angama-24 ishaye phansi olwandle. Yamukelwa ngokushesha ngama-isopods amakhulu, okuthi ngokweNunnally, afana namanqe olwandle olujulile. Bese kuthi abanye abahlanzayo njengama-amphipods, ama-grenadier nezinye izinhlanzi ezimnyama, ezingaziwa ezingaziwa zajoyina lo mkhosi. Ama-isopods aqhaqha lesi silwanana ngokushesha kunokuba ososayensi babelindele, asidla ngaphakathi nangaphandle.
I-alligator yesibili yadliwa ngesikhathi eside. Ngemuva kwezinsuku ezingama-51, okusele kuwo kwakuyizigaxa zawo, ezazinombala obomvu.
“Lowo wasimangaza ngempela. Bekungasalanga ngisho nesikali esisodwa noma isihlava esidunjini, ” UMcClain utshele i-Atlas Obscura. Ithimba libe selithumela uhlaka lwamathambo kuGreg Rouse, ongusosayensi wezasolwandle eScripps Institution of Oceanography, ukuze aqhubeke nokuhlolwa.
URouse uthole ukuthi i-gator yayidilizwe iboshwe ngamaketanga wohlobo olusha lwezibungu ezidla amathambo kuhlobo lwe-Osedax. Lokhu bekungokokuqala ukuthi ilungu le-Osedax litholakale eGulf of Mexico, ngokusho kukaMcClain. Abaphenyi babe sebeqhathanisa iDNA esanda kutholakala naleyo yezinhlobo zase-Osedax esezaziwa, futhi babona ukuthi bathole uhlobo olusha lwenhlanzeko.
Naphezu kokutholakala okumangazayo kohlobo olusha lwe-Osedax, kwakuyi-alligator yesithathu eyashiya ososayensi bedideke kakhulu. Lapho bevakashela indawo lapho i-gator yesithathu yafakwa khona, babebona kuphela ukudangala okukhulu esihlabathini - isilwane sase siphelile nya. Ithimba libe selifuna indawo ezungezile kodwa alitholanga mkhondo we-alligator. Kodwa-ke, basitholile isisindo esinamathiselwe ku-gator, esilele cishe ngamamitha ayi-10 ukusuka esizeni.
Lokhu kusho ukuthi isidlakela esikhukhule i-gator sasinkulu ngokwanele ukuthi singasishwabadela siphelele futhi sidonse isisindo esinamathiselwe ibanga elithile. Leli thimba lisola ukuthi lesi sidalwa kungaba yisigaxa esikhulu noma ushaka omkhulu olinde ukutholakala. "Kusamele ngithole ingwane engadla ingwenya yonke, futhi angifuni ukuba semkhunjini uma singake siyithole."
Abacwaningi ababili bashaqeka ngemiphumela, futhi baneliseka kakhulu ngalokhu kuhlola. Ngokusobala, bahlela ukwenza izivivinyo eziningi ngokulandela le miphumela.
Kungenzeka yini ukuthi i-carnivore engaqondakali ingase ibe yiKraken - isilo sasolwandle esidume ngosayizi omkhulu nokubukeka okufana ne-cephalopod kumlando wabantu baseScandinavia? Noma enye into esingakaze siyicabange nokuyicabanga?
Uma ufuna ukwazi nge-Kraken kanye nezidalwa zasolwandle ezijulile ezingaqondakali funda lesi sihloko esimayelana ne-USS Stein monster engaqondakali. Ngemuva kwalokho, funda ngalokhu Izidalwa ezingama-44 eziyinqaba Emhlabeni. Ekugcineni, yazi ngalokhu 14 imisindo engaqondakali ehlala ingachazeki kuze kube manje.
