I-Yeti Crab, ngokwesayensi eyaziwa ngokuthi kusho ukuthi, ingenye yezilwane eziyinkimbinkimbi nezithakazelisa kakhulu emhlabeni wasolwandle. Ukutholakala kwayo ngo-2005 kwaphawula ingqophamlando kubhayoloji yasolwandle, njengoba ingeyomndeni omusha okuthiwa Kiwaidae. Lezi zidalwa, ezihlala ekujuleni koLwandlekazi iPacific, zithole igama lesidlaliso elithi "Yeti" ngenxa yezimpawu zazo ezihlukile zomzimba, njenge ama-tweezers ambozwe nge-silky filaments okukhumbuza uboya beqhwa elidumile.
Ihlala kuphi inkalankala ye-Yeti?
Inkalankala ye-Yeti ihlala ikakhulukazi e- izindawo ze-basaltic ezungeze izintuba ezishisayo ezishisayo kanye nezindawo ezibandayo ezitholakala ekujuleni kokufika Amamitha angu-2.300. Lezi zimo ezimbi kakhulu, ezibonakala ngamazinga okushisa aphezulu kanye nokungabikho ngokuphelele kokukhanya kwelanga, zenza indawo yazo ibe indawo engathandeki ezinhlotsheni eziningi zezilwane. Nokho, le nkalankala yakhe a ukuzivumelanisa nezimo okuhlaba umxhwele ukuyivumela ukuthi ichume kulezi zindawo ezinezintaba-mlilo.
Ucwaningo lubonisa ukuthi inkalankala ye-Yeti ithanda ama-hydrothermal vents, lapho i- amanzi ashisayo anothile ngamaminerali Inikeza indawo ekahle yokwanda kwamagciwane, abalulekile ukuze aphile. Lezi zilwane zitholakala nasezindaweni ezifana ne-Pacific-Antarctic Ridge kanye namanzi ajulile eduze kwe-Easter Island.
Izici zomzimba ezihlukile
I-Yeti Crab ikala cishe Amasentimitha angama-15 ngobude futhi ibonakala ngomzimba wayo omhlophe, okwenza ibukeke njenge-albino. Le crustacean ayinawo amehlo asebenzayo, okusho ukuthi ayiboni ngokuphelele. Esikhundleni sokubona, isebenzisa imicu yezinzwa yezinsimbi zayo ukuze bona okukuzungezile kanye nesiphakeli.
Ama-tweezers ayo angesinye sezici zayo ezigqama kakhulu. Lezi zimbozwe ngemicu kasilika esebenza njengekhaya lamakoloni amabhaktheriya. Eminye imibono iphakamisa ukuthi la magciwane adlala indima ebalulekile ekukhipheni ubuthi endaweni ezungezile nasekuphakeleni inkalankala, kuyilapho eminye ibonisa ukuthi ingaba yisivikelo ezintweni ezinobuthi ezitholakala emanzini.
Ukudla okunomsoco kanye ne-bacterial symbiosis
El kusho ukuthi unokudla okusekelwe ikakhulukazi amabhaktheriya ekhula emadlazini ayo. Le nqubo yenziwa ngokuhamba njalo kwezitho zayo, okunyakazisa amanzi anamaminerali azungeze imicu yawo, ngaleyo ndlela kukhuthaze ukwanda kwamagciwane. Ngaphezu kwalokho, kuye kwaphawulwa ukuthi iphinde idle ama-microorganisms, izimbaza kanye namanye ama-crustaceans amancane akhona endaweni yawo.
Ubudlelwano be-symbiotic namagciwane buyisihloko esithakaselwa kakhulu ngokwesayensi. Imibono yamanje iphakamisa ukuthi la magciwane angasiza inkalankala ye-Yeti ukuba ukubola izinto ezinobuthi noma isebenze njengomthombo oqondile wokudla, njengoba isimiso sokugaya inkalankala siklanyelwe ukucubungula izinto eziphilayo eziyinkimbinkimbi.
Ukukhiqiza kanye nomjikelezo wempilo
Ngenxa yobunzima bokufunda lolu hlobo endaweni yaso yemvelo, kuncane okwaziwayo mayelana nokuzala kwalo. Kodwa-ke, njengamanye ama-crustaceans, inkalankala ye-Yeti kucatshangwa ukuthi yenza a ukukhulelwa kwangaphandle. Ezisikazi cishe zithwala amaqanda avundisiwe esiswini aze achanyuselwe. Inzalo kufanele ibhekane nobunzima bendawo eyeqisayo kusukela ekuzalweni, okubonisa ukuphakama izinga lokufa ezigabeni zokuqala zokuphila.
Izinsongo nesimo sokulondolozwa
Nakuba okwamanje ingabhekwa njengezilwane ezisengozini yokushabalala, inkalankala ye-Yeti ibhekene nezinsongo ezingaba khona ngenxa yokuxhashazwa kwensiza yangaphansi kolwandle, njengokumba emapayipini ashisayo kanye nokungcoliswa kolwandle. Le misebenzi ingashintsha kakhulu indawo yazo futhi ithinte izimo ezibucayi ezidingekayo ukuze baphile.
Ngaphezu kwalokho, i ukushintsha kwesimo sezulu kungaba nomthelela omubi kuma-hydrothermal vents, ukuguqula amandla ekhemikhali emanzini kanye nebhalansi ye-ecosystem lapho inkalankala ye-Yeti ihlala khona.
Ilukuluku mayelana nenkalankala ye-Yeti
- Igama lesayensi UKiwa livela kunkulunkulukazi wasezinganekwaneni zasePolynesia ezihlobene nezimbaza.
- Ngaphezu kokuthi kusho ukuthi, ezinye izinhlobo zomndeni sezihlonziwe Kiwaidae, njenge- I-Kiwa purelife, etholwe ngo-2006, kanye ne I-Kiwa tyleri, edume ngelika-"Hoff crab" ngenxa yokufana kwayo nesifuba esinoboya somlingisi uDavid Hasselhoff.
- Kuye kwaphawulwa ukuthi izinkalankala ze-Yeti zivame ukuhlangana ndawonye ngokuminyana okufika phezulu Abantu abangama-600 ngemitha yesikwele eduze kwama-hydrothermal vents.
Inkalankala ye-Yeti iyaqhubeka iwuphawu lwezimanga ezifihlwe ekujuleni kolwandle. Ukuzijwayeza kwayo okungavamile kwenye yezinto eziphilayo ezidlulele kakhulu emhlabeni akugqamisi nje kuphela ngobungqayizivele bayo, kodwa futhi kuphakamisa imibuzo ethakazelisayo ngempilo ezimweni ezimbi kakhulu kanye nobudlelwano be-symbiotic enabo nendawo yayo yebhaktheriya. Uma nje isayensi iqhubeka nokuhlola ulwandle olujulile, le crustacean enelukuluku izoqhubeka nokumangala ngezimfihlakalo zayo.
