Iziqhingi zaseGalapagos ziphinde zashiya umphakathi wesayensi ungenalutho. Kulokhu bekungengenxa yezimfudu zazo ezidumile noma ama-iguana asemhlabathini, kodwa ngenxa yokutholakala ekujuleni lapho ukukhanya kwelanga kuyinkumbulo ekude. Ithimba labacwaningi lichaze ngokusemthethweni lokhu I-Microeledone galapagensis, uhlobo olusha lwe-octopus encane engafinyeleli usayizi webhola legalofu futhi evelele ngombala wayo oluhlaza okwesibhakabhaka omangalisayo kanye nenyama yayo ethambile.
Ukuhlangana kokuqala kwenzeke ngesikhathi sohambo lomkhumbi wocwaningo i-E/V Nautilus, ngokubambisana neCharles Darwin Foundation. Ngenxa yerobhothi elingaphansi kwamanzi elihlola amanzi azungeze iDarwin Island, kwathathwa isampula futhi ibilokhu icwaningwa kabanzi. I-Field Museum yaseChicagoLokho okwakubonakala sengathi ithoyizi elincane lasolwandle elithambile sekuphenduke ingxenye ebalulekile ekuqondeni ukuvela kwama-cephalopods ekujuleni kolwandle, indawo iSpain namanye amazwe aseYurophu ayiqapha ngokucophelela ngenani layo lemvelo.
Ubuchwepheshe obusezingeni eliphezulu bokugwema ukulimaza isampula
Ukutadisha isilwane esincane kangaka, okukhona kuso isampula eyodwa kuphela engaphelele, kuletha inselele enkulu kososayensi bezinto eziphilayo. Ngokwesiko, ukuchaza uhlobo kudinga yenza ukuhlukaniswa Ukuze babheke izitho zangaphakathi, umlomo noma i-radula, kodwa kulokhu, uchwepheshe uJanet Voight wakhetha ikhambi eliyinkimbinkimbi kakhulu. Ososayensi basebenzise i-micro-computed tomography enezinqumo eziphezulu, eyabavumela ukuthi bakhiqize i- imodeli enemininingwane emithathu kwesimo sayo sangaphakathi ngaphandle kokususa ngisho nelilodwa itende endaweni yalo.
Ngenxa yalobu buchwepheshe be-X-ray, kwatholakala ukuthi isampula yayiyisifazane esivuthiwe esasinezimbongolo. Amaqanda amakhulu ayi-13 akhulayo ngaphakathi. Le ndlela engonakalisi ibeke isibonelo esibalulekile ekuhleleni kwesimanje, okuvumela isampula kuphela etholakalayo Ihlala isesimweni esifanele sokubonisana esikhathini esizayo emnyuziyamu, ngaleyo ndlela igweme ukulahleka kolwazi lwebhayoloji olungenakufakwa esikhundleni oluvame ukwenzeka ngezindlela zokutadisha zakudala.
Ingwane ephula isikhunta esimisiwe
Lesi silwane esincane esihlala emanzini ajulile singowomndeni wakwaMegaleledonidae, iqembu elivame ukuhlotshaniswa namanzi abandayo kakhulu, njengalawo ase-Antarctica. Kodwa-ke, ukuthola amanzi abandayo I-Microeledone galapagensis emanzini ase-equator Iqiniso lokuthi lingaphansi kwamamitha angu-1.773 liphoqe ukuthi kucatshangelwe kabusha amamephu okusatshalaliswa kwalezi zilwane, afana nendawo yokuhlala neyase-US. i-dumbo octopusLesi sidalwa sinesikhumba esibushelelezi ngendlela emangalisayo futhi asinayo isikhwama seyinki, into esingayenza, masibe neqiniso, Akusizi kakhulu. ebumnyameni obukhulu bolwandle.
Enye yezinto ezithakazelisa kakhulu ngale octopus yindlela yayo yokuzifihla ngemuva. Nakuba umhlane wayo uphaphathekile, ingxenye engaphakathi yengubo yayo ine- onsomi ojulile noma oluhlaza okwesibhakabhakaOchwepheshe bakholelwa ukuthi lokhu kuyasiza ekufihleni ukukhanya okuvela ezilwaneni ezidlayo. Lokhu kuvimbela isisu saso ekukhanyeni njengesibani futhi kudonsele izilwane ezinkulu ezicashe endaweni. ukuzivumelanisa nezimo okumangalisayo kokuziphendukela kwemvelo ukusinda kwalasha.
Ukuxhumana nalo lonke uLwandlekazi iPacific
Ucwaningo lusikisela ukuthi le ngwane inesihlobo esiseduze, i-M. mangoldi, esitholakala eNew Caledonia, empumalanga ye-Australia. Lokhu kubonisa ukuthi kukhona isixhumanisi esijulile sokuziphendukela kwemvelo phakathi kwezinhlobo ezihlukaniswe ngamakhilomitha ayizinkulungwane zamanzi, okuphakamisa ukhokho ofanayo owayehlala ezindaweni eziphakathi kwePacific. Lolu hlobo lokuthola lugcizelela ukuthi kuncane kangakanani esikwaziyo ngempela ngeplanethi yethu, njengoba kulinganiselwa ukuthi asikayihlolisisi kahle i- ingxenye encane kakhulu yolwandle.
Kubalulekile ukukhumbula ukuthi lezi zindawo zemvelo azinakulimazwa. Ukushintsha kwesimo sezulu nakho kuyathinta kuya ekujuleni okukhulu, kushintsha izinhlelo esingakaqedi ngisho nokuzihlela ngaphambi kokuba zinyamalale. I-Microeledone galapagensis iyisikhumbuzo sabacebile ukuhlukahluka kwezinhlobo zasolwandle okusacashe ngaphansi kwamagagasi kanye nokubaluleka gcina imizamo yokulondoloza ezindaweni eziphephile zasolwandle zomhlaba wonke ukuvikela laba omakhelwane abanolwazi bale planethi esiphila nabo.
Ukutholakala kwale octopus encane eluhlaza okwesibhakabhaka kuphawula ingqophamlando ekuhlolweni kweziQhingi zaseGalápagos ngokuveza uhlobo lwe-cephalopod olunezimo ezihlukile zokuphila olwandle olujulile. Ngenxa yalokhu ukubambisana kwesayensi kwamazwe ngamazwe Ngenxa yokusetshenziswa kwezindlela ezingangenisi uhlaselo ezifana ne-tomography, lesi silwane esincane sitholakale ngaphandle kokubeka engcupheni ubuqotho besampula yokuqala. Lokhu kutholakala akugcini nje ngokwandisa uhlu lwezinhlobo ezitholakalayo zalesi siqhingi, kodwa futhi kunegalelo idatha ebalulekile ngokuziphendukela kwemvelo kwezilwane ezijulile ePacific kanye nesidingo esiphuthumayo sokuqhubeka nokuhlola indawo enkulu kangaka nengaziwa.
