I-Dumbo octopus yaqoshwa okokuqala ngqa oLwandle lwase-Argentina. ngesikhathi sohambo lwesayensi lwe-Continental Slope IV, nesibonelo sohlobo lwe-Grimpoteuthis olubonwe ekujuleni okungamamitha angu-3.781 e-Mar del Plata Submarine Canyon ngenxa yemoto esetshenziswa ukude i-ROV SuBastian.
Ngamaphiko ayindilinga phezu kwamehlo kanye nombala obomvana, I-cephalopod yavela endaweni engenakukhanya, cishe ngo-2 °C nokucindezela okukhulu, ekuqapheliseni okungahlanyisi okuhlanganiswe i-Schmidt Ocean Institute ngokubambisana nochwepheshe abavela ku-CONICET kanye ne-INIDEP.
Irekhodi elingakaze libonwe eMar del Plata Canyon
I-submarine slope kanye nomsebenzi wokuhlola we-canyon ubuchwepheshe obusezingeni eliphezulu obuhlangene nobungcweti bebhayoloji ukubhala ingwane ngaphandle kokuyisusa endaweni yayo, ukulondoloza umongo wemvelo nokuziphatha kwemvelo kwesilwane.
Ithimba lisebenzise i-ROV SuBastian cishe amakhilomitha amane ngaphansi komhlaba futhi ithwebule izithombe ezicacile ze-Grimpoteuthis ezihamba phezu kwenhlabathi ihamba kahle, iqhutshwa amaphiko ayo kanye nolwelwesi oluxhuma izingalo zayo.
Ababephethe ucwaningo bakugqamisa lokho Leli irekhodi lokuqala emanzini kazwelonke yengwane evela kuleli qembu, egqamisa ukungajwayelekile kombala obomvana ochazwe kanye nokubaluleka kokuwubuka uphila endaweni yawo.
Ibukeka kanjani ingwane ye-Dumbo nokuthi kungani iheha
Ingwane ebizwa ngokuthi i-Dumbo octopus ingeyohlobo I-Grimpoteuthis, ebonwa amaphiko avela ngenhla kwamehlo futhi Zifana nezindlebe, isici esivumela ukuthi ikwazi ukunyakazisa futhi iziqhubele ngokwawo ngokusebenza kahle okukhulu emanzini ajulile. Uma ungathanda ukufunda okwengeziwe ngezici zale cephalopod, ungavakashela Olunye ulwazi mayelana nengwane ye-Dumbo.
Ifakwe phakathi kwalokho okuthiwa izambulela octopus, iqembu eliboshwe ulwelwesi ukuthi ihlanganisa izingalo bese yenza iphrofayili ehlangene ne-gelatinous, ilungele ukuhamba ngobuhlakani phansi olwandle.
Izilinganiso ezijwayelekile zizungezile 20-30 amasentimitha, nakuba kuye kwachazwa abantu abakhulu. Umzimba wayo othambile, ocwebezelayo wenza kube lula ukufihla kanye nokushintshashintsha kokungathathi hlangothi.
Ngokungafani nama-octopus amaningi, akanalo isaka likayinkiEbumnyameni obukhulu, ukufihla i-chromatic nokunyakaza okuthulile kusebenza kangcono kunokukhulula ifu.
Idla izilwane ezingenamgogodla ezingaphansi, kuhlanganise ama-mollusk amancane, izikelemu nama-crustaceans, eliwathwebula ngezinkomishi zokumunca ezinemicu yezinzwa bese liholela emlonyeni ophakathi nendawo ezingalweni.
Ukuzijwayeza kwalasha: igazi eliluhlaza, ukudla nokunyakaza
Ukusetshenziswa kwe-Dumbo octopus i-hemocyanin ecebile yethusi, okunikeza umbala oluhlaza okwesibhakabhaka egazini futhi kuthuthukise ukuthuthwa komoyampilo ngaphakathi amanzi abandayo kakhulu futhi angenawo umoya-mpilo, izici ezijwayelekile zendawo ye-abyssal. Ibhayoloji nokuziphatha kwabo nakho kwembula ukuzivumelanisa okumangalisayo nokuphila ekujuleni.
Isu labo lokudla lisekelwe thola, ncela, futhi ugwinye inyamazane yonke, umsebenzi owenziwe ukungabikho koqhwaku oluqinile oluvelele kanye nekhono layo loku shintsha umbala ukuze ungabonwa izilwane ezidla ezinye.
Ngokuqondene nokuhamba kwayo, ishintshanisa nokubhakuzisa amaphiko ayo ukunyakaza okuguquguqukayo kwejazi nezingalo, ikhiqiza inqubekelaphambili ezinzile, eyonga amandla, ilungele indawo lapho zonke izisetshenziswa zibalulekile.
Lezi zilwane nginesizungu okukhiqizwa kwawo kwenzeka ngezikhathi ezithile; owesilisa udlulisa iphakethe lesidoda bese owesifazana ungayigcina isikhathi eside ukuvundisa nokubekela amaqanda lapho izimo zivuma.
