Nautilus pompilius - ummeleli omkhulu ongavamile wama-cephalopods avela kuhlobo olwaziwa kakhulu i-Nautilus. Lolu hlobo luhluke ngempela, njengoba ososayensi abaningi nabadwebi bakha izinto ezinhle ezivela kumagobolondo alo ngesikhathi se-Renaissance. Namuhla, indalo yabo ingabonakala kuKhabinethi Yezinto Ezifuna ukwazi. Into ejwayelekile kakhulu engabonakala yisitsha sokucwila, okwenziwe ngama-jeweler hhayi ukusetshenziselwa okusebenzayo, kepha kwenziwa umhlobiso wasekhaya kuphela.
Umsuka wezinhlobo nencazelo
Isithombe: Nautilus pompilius
Kufanele siqale ngeqiniso lokuthi, ngokujwayelekile, i-nautilus iyona kuphela uhlobo lohlobo ngokwesiko olunikezwe uhlobo lwesimanje se-nautiloid subclass. Kwamukelwa ngokuvamile ukuthi ama-nautiloid okuqala avela ngesikhathi seCambrian, okungukuthi, asuka ezigidini ezingama-541 kuya ezigidini ezingama-485 edlule. Lolu hlobo lwakhula ngokushesha ngesikhathi sePaleozoic (eminyakeni eyizigidi ezingama-251 edlule). Kwakukhona isikhathi lapho bacishe bafa, njengezihlobo zabo ama-ammonite, kepha lokhu akwenzekanga, izinhlobo, njengohlobo lonke, zisaphila kuze kube namuhla.
Zonke izinhlobo ze-nautilus ziyefana. Okwamanje, kuyaziwa ngokuba khona kwezinhlobo ezi-6 zala ma-mollusk, kepha, izinhlobo esizicabangayo, ngokusho kososayensi, zingenye yezokuqala ezavela emhlabeni. Izigidi eziningi zeminyaka edlule, ubukhulu bazo bebungafinyelela kumamitha ayi-3.5 ubude. Namuhla, igobolondo lezinhlobo ezinkulu kakhulu lisukela kumasentimitha ayi-15 kuye kwangama-25 ububanzi.
Nautilus pompilius inokubukeka okuthakazelisa ngempela. Imollusk ihamba ngokungavamile ngaphansi kwamanzi, ngakho-ke umuntu ojwayelekile, ngokwesibonelo, osanda kuqala ukudilika, akakwazi ukusho ngokuqinisekile ukuthi hlobo luni lwesidalwa. Isilwane, ngendlela esingazwakala ngayo, sihlala sisesimweni esithile sokuwa ngenxa yokuma kwegobolondo laso, esizokhuluma ngalo ezigabeni ezilandelayo.
Ukubukeka nezici
Isithombe: Nautilus pompilius
Nautilus pompilius inezici ezithile ezisiza ukuhlukanisa nezinye izinhlobo zohlobo lweNautilus. Njengoba kushiwo ngaphambili, namuhla kunabantu abakhulu kakhulu, ububanzi begobolondo obufinyelela kumasentimitha angama-25. Lezi zinhlobo yi-nautilus pompilius esiyicabangayo.
Ake sikhulume ekuqaleni ngegobolondo lesilwane. It is twisted in a spiral, kanti ngaphakathi kuye kwahlukaniswa kwaba amakamelo. Isigaba esikhulu kunazo zonke sisebenza emzimbeni we-mollusk, kanti konke okunye kusetshenziselwa ukucwilisa noma ukukhuphuka. La magumbi angagcwaliswa ngamanzi, avumela i-nautilus ukuthi yehlele ekujuleni okukhulu, noma ngomoya, oyivumela ukuthi inyuke iye phezulu. Igobolondo lesilwane linombala we-brindle.
Umzimba we-mollusk, njengezinye izilwane eziningi, ulinganayo, kodwa futhi unokwehluka kwawo. Njengoba sazi, ama-cephalopods amaningi anamaswidi ezingalweni noma ezintendeni zawo, kepha lokhu akusebenzi ezinhlotsheni esizicabangayo. Imilenze yabo isetshenziswa kakhulu ukubamba isisulu nokuhamba emanzini. Umlomo we-nautilus pompilius unamahlumela angaphezu kwama-90.
Amehlo asekhanda lesilwane atholakala, njengamanye amalungu ohlobo, kepha awanayo i-lens. Futhi kule ngxenye yomzimba kunamathente amaningana wokuvunda asabela kumvelo yangaphandle.
Ihlala kuphi i-nautilus pompilius?

Namuhla, i- nautilus pompilius ingatholakala olwandle olunjengePacific naseNdiya. Indawo yabo yokusabalalisa ayinabanzi kakhulu, kepha kwezinye izindawo inani labo lingafinyelela amanani ahlaba umxhwele impela. INautilus ihlala ekujuleni kwamamitha ayi-100 kuye kwangama-600, kepha izinhlobo esizicabangayo kaningi aziweli ngaphansi kwamamitha angama-400.
Njengendawo yazo yokuhlala, lezi zilwane zikhetha ukuhlala emanzini asezindaweni ezishisayo. Zivame ukutholakala eduze kwemifula yamakhorali ekujuleni kwamanzi. Phakathi kwalawa makhorali, angacasha kalula futhi avikele engcupheni engase ivele.
Ukukhuluma ngendawo yezwe, kubalulekile kuqala ukuphawula ogwini lwalawo mazwe lapho kuhlala khona inani elikhulu lalezi zinhlobo. Ngakho-ke, i-nautilus pompilius ingatholakala eduze kwezindawo eziningi:
- I-Indonesia
- IPhilippines
- ENew Guinea
- IMelanesia (iqembu leziqhingi ezincane ezisePacific Ocean)
- E-Australia
- Micronesia (iziqhingi ezincane ezifana ne-Oceania njengeGilbert, Mariana, Marshall)
- IPolynesia (isifunda sase-Oceania esifaka iziqhingi ezingaphezu kwe-1000)
Yini edliwa yi-nautilus pompilius?

Ukudla kwe-nautilus pompilius akuhlukile kakhulu kwabanye abamele uhlobo lwe-shellfish. Njengoba behola indlela engokwemvelo yokuphila futhi baqoqa izilwane ezifile nezinsalela zezinto eziphilayo, kungabikwa eqenjini labagcobi. Kukho konke lokhu, kaningi badla izinsalela zamagobolondo ama-lobster. Kodwa-ke, lokhu kudla kuthatha kuphela isigamu sokudla kwabo.
Ingxenye esele ukudla kwezilwane. Ngezikhathi ezithile, le mollusk ayiphikisani nokudla ama-crustaceans amancane, okuyi-plankton. Ngaphezu kwalaba bameleli abaphilayo bezilwane, amaqanda noma izibungu zezinhlanzi eziningi ezihlala olwandle nazo zingaba yisisulu sabo. Lokhu kudla kumane kuthathe ingxenye esele yokudla kwalolu hlobo.
INautilus pompilius, njengoba sishilo ekuqaleni, abanayo i-lens yamehlo, ngakho-ke ababoni kahle isisulu sabo. Ngaphandle kwalokhu, zinhle impela ekuhlukaniseni imibala ethile emanzini futhi sezingakwazi ukunquma isidlo sasemini ngazo.
Izici zobuntu nendlela yokuphila
Isithombe: Nautilus pompilius
Nautilus pompilius kuhola indlela yokuphila ezolile nenesilinganiso. Angase angazifuneli ukudla isikhathi eside, esihlala inyanga eyodwa. Isikhathi esisele sihlala cishe endaweni eyodwa yokuhlala kwaso, ngokwesibonelo, eduze kolwandle oluthile lwamakhorali. Lezi zinhlobo zilawula ukuqhuma kwazo ngendlela yokuthi zikwazi “ukundiza” zinganyakazi endaweni eyodwa isikhathi eside. Isikhathi sokuphila se-nautilus pompilius siyahluka kusuka eminyakeni eyi-15 kuye kwengama-20.
Isilwane sigcina ekujuleni okuphansi emini - kusuka kumamitha angama-300 kuye kwangama-600, kanti ebusuku, uma kunesidingo, sikhuphukela kumamitha ayi-100 ukuzitholela ukudla. Akalinqobi uphawu lwamamitha ayi-100 ngokunembile ngoba izinga lokushisa lamanzi lapho liphakeme kakhulu kunelejwayelekile. Ekujuleni okungajulile, i-nautilus pompilius ingafa.
Iqiniso elithakazelisayo: isilwane siyehla senyuka njengohlobo oluthile lwesikebhe solwandle. Yingakho anikezwa elinye igama - isikebhe solwandle.
Esikhathini esingengakanani esidlule, abacwaningi benza ucwaningo, ingqikithi yalo okwakungukuthola amakhono engqondo omele izilwane. Bafaka isicupho socingo, futhi ngaphakathi babeka izingcezu ze-tuna njengesithiyelo. UNautilus wabhukuda lapho futhi, ngeshwa, akakwazanga ukubuyela emuva. Leli qiniso libonisa amakhono aphansi engqondo ohlobo.
Isakhiwo senhlalo nokuzala
Isithombe: Nautilus pompilius
Izinhlobo ze-nautilus pompilius zingowesilisa nowesifazane, kepha, ngenxa yokuba khona kwazo njalo ekujuleni okuphezulu ngokwanele, isimilo sazo ngesikhathi sokukhwelana asikaze sifundwe nakwabanye abamele izilwane zasolwandle.
Ososayensi bathole ukuthi ngaphambi kokukhulelwa, abesilisa balwa bodwa, okufana nokulwa komqhudelwano. Ngakho-ke, bancintisana nommeleli wesifazane oyifunayo. Ngokusobala, le nqubo yenzeka ngenxa yesilinganiso esiphansi sabesilisa nabesifazane emadwaleni afanayo. Kungahlukahluka kuye ngesibalo sabantu, kepha kuzo zonke inani labesilisa liyinhloko.
Ngemuva kokukhetha owinile, owesifazane ukhuleliswa ngqo. Ngenxa yezinsimbi zayo eziguquliwe, owesilisa udlulisela imbewu emhlubulweni wodonga lomzimba wesifazane, olusemngceleni wesikhwama sangaphakathi nomlenze, kwakheka uhlobo lwephakethe.
Ngemuva kokukhulelwa, abesifazane bahlanganisa amaqanda, anegobolondo elijiyile, ematsheni ajulile ngangokunokwenzeka endaweni abahlala kuyo. I-Nautilus pompilius ivame ukuqanduselwa ngemuva kwezinyanga eziyi-12. Izingane zivame ukuba ngamasentimitha ama-3 ubude, futhi amagobolondo azo aqukethe ikamelo elilodwa elinikezelwe emzimbeni. Ngokwesilinganiso, abantu abangavuthiwe bakhula ngamamilimitha ayi-0.068 ngosuku.
