Isivinini sokunyakaza kofudu emhlabeni nasemanzini: ukuthi ulwandle, umhlaba kanye nofudu olunamadlebe abomvu lugijima futhi lubhukude kanjani (isivinini esimaphakathi nesikhulu sokunyakaza)

Ezinganekwaneni zamazwe ayengaphansi kweSoviet Union, umfanekiso wofudu uhlotshaniswa ngendlela engenakuhlukaniswa nokunensa. EziQhingini zaseFiji, isilwane esihuquzelayo, ngokuphambene nalokho, siwuphawu lwejubane. Izakhamuzi ziyazihlonipha lezi zilwane ngenxa yamakhono azo angenakuqhathaniswa nokushesha okubonisa izilwane ezihuquzelayo emanzini.

Izinto ezithinta ijubane lokuhamba kofudu:

• isisindo kanye nesakhiwo segobolondo;
• i-anatomy yezidladla;
• Ukushisa komzimba;
• isimo somzwelo;
• izici ezingaphezulu;
• ubudala kanye nesimo somzimba.

Ubude bemilenze kubameleli bezinhlobo ezikwazi ukufihla izidladla zabo nekhanda ngaphansi kwegobolondo bufushane, ngakho-ke amandla abo aphansi kakhulu kunalezo zinhlobo ezingakwazi ukwenza lokhu (ufudu olunekhanda elikhulu, i-vulture turtle, izimfudu zasolwandle).

Ijubane lofudu ezweni liphansi kunasemanzini.

Ijubane lomhlaba

Izilwane ezihuquzelayo, izidladla zazo zibukeka njengama-flippers, zihamba ngokunethezeka okuncane, kodwa azihlali zihamba kancane. Ezimweni ezinethezekile, isilwane esihuquzelayo sincamela ukukhasa kancane. Ukwenyuka kwejubane kwenzeka uma isilwane sizwa ingozi, noma sinentshisekelo ejulile entweni ethile ekude. Gijima, ngomqondo ogcwele wegama, okungukuthi, ngesikhathi esithile ungathinti phansi, isilwane esihuquzelayo asikwazi. Kodwa uma kunesidingo, bangasheshisa kakhulu.

Izimfudu ezinomzimba othambile zigijima ngokushesha. Ngenxa ye-ossification ebuthakathaka kanye nesimo esiyisicaba segobolondo, bayakwazi ukusheshisa ngokushesha kumazinga aphezulu. Isivinini esikhulu sofudu olusemhlabeni ngu-15 km/h.

Abantu abasha bayashesha kunabantu abadala, impilo yabo incike kuyo endle.

Amatshe asolwandle emhlabeni azizwa ecindezelekile, ngenxa yesakhiwo sezidladla, okukhumbuza kakhulu ama-flippers. Asezingeni eliphansi kakhulu ngesivinini sokuhamba kunezinhlobo zasemanzini ahlanzekile, kodwa azoqhudelana nezinhlobo zasemhlabeni.

Ijubane lofudu lwasemhlabeni livame ukuhamba kancane kunezinhlobo zamanzi ahlanzekile. Ukudla kwezitshalo akudingeki ukuba kubanjwe, ngakho ukuziphendukela kwemvelo kukhethe igobolondo njengendlela yokuqala yokuvikela. Uma kwenzeka ingozi, kwanele ukuba bafihle ikhanda nezidladla zabo.

Isivinini esikhulu sofudu lwasemhlabeni ngokwesilinganiso asidluli ku-0,7 km / h. Irekhodi elirekhodiwe ngokusemthethweni labekwa ngumuntu oyedwa wohlobo lwengwe futhi lilingana no-0,9 km/h.

Ufudu olukhulu lwaseSeychelles lubonwa njengolunensa phakathi kwezimfudu zasemhlabeni. Ngomzuzu, uyakwazi ukunqoba amamitha angaphezu kuka-6,17, ngoba ijubane lakhe alidluli ku-0,37 km / h.

I-Gopher ne-star turtles igijima kancane, cishe i-0,13 m / s. Ngesikhathi esifanayo bangavala amamitha angu-7,8.

Isivinini esijwayelekile sofudu luyi-0,51 km/h.

Abanikazi bezilwane zase-Asia Ephakathi bayaqaphela ukuthi izilwane ezifuywayo ziyasebenza futhi ziyasebenza. Ufudu lwase-Asia Emaphakathi lukwazi ukuhamba amamitha angu-468 ngehora. Ijubane layo alidluli ku-12 cm/s. Umhlabathi ongemuhle awuyona inkinga kusilwane esihuquzelayo. Imithambeka ewumqansa kanye nezinto ezixegayo ezingaphansi kwezinyawo azikwazi ukumvimbela ukuthi aye phambili.

Isivinini sokunyakaza emanzini

Izinhlobo zasemhlabeni zingaphila emanzini isikhathi esithile, kodwa abantu abaningi abakwazi ukubhukuda. Ukuhlala isikhathi eside ngaphandle kwesici somdabu kuyingozi ezilwaneni. Izidladla ezingenawebhu kanye nedizayini ye-carapace emide ayakhelwe ukugijima emanzini.

Izimfudu zamanzi ahlanzekile zinezimbotshana phakathi kweminwe, igobolondo liphansi futhi libushelelezi. Lokhu kuzivumela ukuthi zithuthukise ijubane elimangalisayo. I-Dynamics inomthelela ekuzingeleni okuphumelelayo kwezinhlanzi nezilwane zasemanzini.

Izimfudu ezinkulu ze-leatherback zibhukuda ngesivinini esiphindwe izikhathi ezingu-14 kunesikashaka waseGreenland futhi cishe elilingana nelomkhomo.

Ijubane lezimfudu zasolwandle emanzini liphezulu, njengoba igobolondo eliqondile, eliyisiyingi kanye nemilenze yangaphambili emise okwe-flipper iyasiza kakhulu ekujuleni. Ngokwesilinganiso, ziphakeme kulezi zinhlobo zamanzi ahlanzekile.

Izibonelo zesivinini sokubhukuda zamatshe olwandle:

• ufudu lwasolwandle - 18 km / h;
• ulwandle oluluhlaza - 32 km / h;
• ufudu lwesikhumba - 35 km / h.

Ukuthi ufudu lubhukuda ngokushesha kangakanani akuxhomekile kuphela emininingwaneni yalo ebonakalayo. Amathuba athonywa isiqondiso sokugeleza, ukuminyana kanye nezinga lokushisa kwamanzi.

Isivinini sofudu olunamadlebe abomvu

Endaweni yayo yemvelo, ukudla kobuhle obunamadlebe abomvu kungama-40% amaprotheni. Amagobolondo nezinhlanzi ezincane ziyadliwa. Ngomzuzu, izinhlanzi zasemfuleni zigcina isivinini esiphakathi kuka-0.3 m, futhi zingafinyelela ku-2 m / s, okungavimbeli isilwane esihuquzelayo ekuzingeleni. Izimfudu zibhukuda ngesivinini esingama-5-7 km / h, futhi isivinini esikhulu se-turtle enamadlebe abomvu singadlula lezi zibalo.

Ezweni, ufudu olunamadlebe abomvu lungaphansi kancane kumarekhodi alo emanzini. Uma kwenzeka ingozi, isilwane sivame ukucasha emthonjeni wamanzi oseduze, lapho sizizwa siqiniseka ngokwengeziwe.

Ufudu olunamadlebe abomvu luhamba phambili ngokuhamba kodade ngokubukeka. Angakwazi ukuhamba amakhilomitha amaningana ngosuku. Ngokuhambisana nohlelo oluhle lokuzala, lokhu kuvumela isilwane esihuquzelayo ukuthi sithuthukise ngokushesha izindawo ezintsha futhi siqhudelane nezakhamuzi zaso. Ufudu olunamadlebe abomvu lufakwe ohlwini olusemthethweni "lwezinhlobo eziyi-100 eziyingozi kakhulu ezihlaselayo" ezivela ku-IUCN.
