Isilwane sezilwane zasolwandle esisolwandle

Cabanga ukuthi ngenkathi uhamba olwandle ngezansi uzothola isisindo esishiyekile, ngisho nombala obomvu. Amazing? Yebo! Ikakhulukazi ngoba kungase kube yilezi zilwane ezingavamile kakhulu zesayensi yanamuhla. Izakhamuzi zamanzi olwandle nolwandle ngokuvamile aziqondi kahle. Yingakho kuyathakazelisa kakhulu ukufunda okuthile okusha kusuka kwizilwane. Ake sizame ukuqonda lokho okuhlala khona olwandle - isobho elibomvu.

I-sock noma igxiliwe ibhola?

Lesi simangaliso semvelo saqala ukutholwa eminyakeni engaphezu kwengu-60 eyedlule futhi, ngaphezu kwamagama asesayensi ezisemthethweni, aqine ngokuqinile ngemuva kwawo uqobo igama elingabizwa ngokuthi "i-purple sock". Incazelo yalesi silwane sasolwandle sincishisiwe kulezi zimpawu: umbala obomvu, umumo ongapheli okukhumbuza inzwane ekhonjiwe noma ibhaluni, elalikhunjulwa, nebhodi elilodwa elincane.

Igama elisemthethweni lesayensi le-puzzle ye-sea yi-Xenoturbella. Emvelweni kukhona izilwane zamasayizi ahlukahlukene, amakhulu kunawo wonke afinyelela isigamu semitha ubude. Ngenxa yobukhulu obukhulu kakhulu, lezi zinhlobo zitholakale kusigaba esihlukile, zibiza nge-Xenoturbella monstrosa. Kulezi zici ezithile zesilwane esibizwa ngokuthi "i-sock purple" ekupheleni, kodwa ukungavamile kuqalile nje.

Izitho ezengeziwe?

Ukucwaninga okuningiliziwe kwalesi sihlala phansi kwamanzi angaphansi kwamanzi ososayensi abaphazamiseke kakhulu. Kwakukhona ukuthi isobho elibomvu yisilwane sasolwandle esingenalo ubuchopho, umgogodla noma ngisho namathumbu okugaya ukudla. Isigungu esisodwa esitholakalayo emzimbeni walesi simangaliso sivulekele ngesikhathi esifanayo sokungena nokuphuma kokudla.

Ekuqaleni, ososayensi bakwazi ukuhlukanisa i-DNA ye-sock ebomvu, okwakubonisa ukuthi kwakuyimeleli yekilasi lezimvukuzane. Kodwa ngokuhamba kwesikhathi kwavela ukuthi isobho elibomvu limane likopishe i-DNA yezokudla okukudlayo.

Ukuqhubeka kusukela eqinisweni ukuthi abameleli bezinhlobo zezilwane zasolwandle bavame ukutholakala ezindaweni zokuhlala zezimvukuzane, kungacatshangwa ukuthi yibo abadla ukudlala. Kodwa njengoba kwenzeka - ngoba ososayensi, futhi, imfihlakalo.

Iqiniso liwukuthi i-sock ebomvu ayinayo amazinyo, noma i-villi yokuxosha ukudla, noma i-proboscis. Ngakho-ke, ngokuqondile ukuthi ukudla kungena kanjani ekuvulekeni komlomo, kuhlala futhi esigabeni esingenakuqondakala.

Ungayitholaphi lesi simangaliso semvelo?

Ngeshwa, nje ukubhukuda ehlobo elwandle, isimangalo esinjalo asitholakali. Indawo yokuhlala yalesi sidalwa i-Pacific Ocean. Ngesikhathi sokuqala bathola i-sock ebomvu ngo-1949. Njengoba lesi silwane sitholakala njalo, isibalo saso sincane kakhulu.

Indawo esiseduzane nomuntu, lapho ungathola khona lezilwane zasolwandle, ungunxweme lwaseCalifornia.

I-Sock ene-mission ephezulu

Izingxabano zesosayensi ngokuhlelwa kwe-Xenoturbella zafinyelela isivumelwano sokuthi lesi silwane singezilwane ezilula kakhulu ezihlobene nezibungu. Ukucwaninga kwalo kuqhubeka, kodwa abacwaningi basolwandle basho ngokungaqondile - lesi silwane sasolwandle sifike kithi kusukela ezinkathini zokuqala zokuziphendukela kwemvelo, ukuze singabizwa esinye sezizakhamuzi ezindala kunazo zonke emhlabeni.

Ucwaningo oluningiliziwe lwe-sock elibomvu luzovumela ososayensi ukuba bagcwalise izikhala ezikhona ngolwazi mayelana nenqubo yokuziphendukela kwemvelo futhi baqiniseke ngesibonelo esibonakalayo. Ngemuva kwalokho konke, i-Xenoturbella, noma i-sock ebomvu, isilwane izitho zayo ezingakakhuliswa. Ngakho-ke, ulwazi lalesilwane lubonisa ukuthi izitho ezinjalo ezibalulekile njengezobuchopho, amehlo, amathumbu nabanye, ngaphandle kokunye okuphilayo okungeke kube khona, kwakhiwa ngesikhathi sokuziphendukela kwemvelo, futhi i-lilac sock isebenza.

Phakathi naleso sikhathi, le mfihlakalo yezilwandle ayifuni ukudalula zonke izimfihlo zayo: ososayensi abazange bakwazi ukubona indlela i-sock ebomvu ethatha ngayo ukudla futhi ikhululiwe ekudleni okuvele kulayishiwe.
