Ukunciphisa ukuThambisa izilwanyana kwiLizwe
Ngokumalunga kakhulu ne-armadillos kunye neendawo zokudlala, ama-sloth avela eMzantsi Melika kwixesha elide lase-Eocene, "ukusa kwimihla yokuphila kwangoku," xa uMzantsi Melika "waba yindlu ekhethekileyo yezilwanyana ezinamafutha, ama-edentates, ama-marsupial, kunye neentaka ezininzi ezingenamanzi. (Phorusrachids). " Kwakukho ngezinye iintlobo ezingama-35 zeelnet, ukusuka kwi-Antartica ukuya kwi-Central America. Ngoku kukho izilwanyana ezimbini ezihlala ezintlangeni zemvula zaseCentral naseMzantsi Melika.
Kukho iintlobo ezimbini ze-sloth ezinamacala amabini eMzantsi Melika-(iCholoepus hoffmanni okanye i-Unau) efumaneka kwimimandla ehlathini enyakatho eMzantsi Melika ukusuka e-Ecuador ukuya eCosta Rica, kunye no- Choloepus didattylus eBrazil. Kukho iintlobo ezintathu zentlanzi ezintathu (Bradypus variegatus) kwi-Ecuador yonxweme, ngokusebenzisa i-Columbia neVenezuela (ngaphandle kweLlanos, kunye ne-delta e-Orinoco), eqhubekayo kwimimandla ehlathini yase-Ecuador, ePeru, eBolivia, ephuma eBrazil kwaye isondela kwingxenye esenyakatho yeArgentina ne-Central America,

Ukwahlukana phakathi kweentlobo, njengoko kuthiwa, kusemagqabeni angaphambili, njengoko zombini umgca uneminyango emithathu kwienyawo zawo, kodwa azixhamli iintsapho.
Izilwanyana ezihamba ngokugqithiseleyo zehlabathi, iintlanzi zaseMzantsi Melika zihlala kwiimithi, ezikhuselekileyo ezisuka kumhlaba. Benza ininzi yemisebenzi yabo exhomekeke phantsi emithini. Badla, balala, baqabane, bazala, kwaye banamathele abantwana babo abasemhlabeni.
Kuthatha iminyaka engamashumi amabini nesigxina ukukhula ubukhulu obukhulu, phakathi kweenyawo kunye neyesibini kunye nesiqingatha seenyawo. (Okhokho babo, i-Giant Sloth ephelayo, ikhulile ibe yindlovu.) Bahlala iminyaka engamashumi amane.
Ngenxa yobomi "obunqamlekileyo", izitho zawo zangaphakathi ziindawo ezahlukeneyo.
I-Sloths iyancipha kakhulu emhlabeni, ihamba kuphela malunga neenyawo ezingama-53 ngeyure.
Ngokukhawuleza kwimithi, banokuhamba malunga neenyawo ezili-480 / iiyure, kwaye kwiimeko zengxamiseko ziye zalandelwa zihamba ngeenyawo ezili-900 / iyure.
I-Sloths ikhetha indlela yokuphila ekhawulezayo. Bachitha ixesha elininzi lokuphumla komhla nokulala. Ebusuku, badla, behla baye emhlabathini kuphela ukufudukela kwenye indawo okanye ukuxhathisa, ngokuqhelekileyo kanye ngeveki.
Izitiya zaseMzantsi Melika zizityalo kwaye zidla amaqabunga omthi, amahlumela kunye nezinye iziqhamo. Iintlobo ezimbini zentlanzi nazo zidla amahlumela, iziqhamo, kunye nezilwanyana ezincinci. Iinkqubo zabo zokugaya zincinci, ngenxa yeendlela zabo zokuzonwabisa ezinokuzonwabisa, ezivumela ukuba baphile ngokutya okuncinci. Bafumana amanzi abo emanqeni okanye ijusi emaqabini. Le nqanaba ephantsi ye-metabolism yenza kube nzima kubo ukuba balwe nezifo okanye iindawo ezinzima.
Zinexesha elide, iminqamlezo ephihliweyo evumela ukuba bathabathe isebe lomthi kwaye baxhomeke nangona balele. Basebenzisa imilomo yabo, enzima kakhulu, ukutshala amaqabunga. Ukukhula ngokuqhubekayo nokuzimelela, amazinyo abo agaya ukutya kwabo. Bangasebenzisa amazinyo abo ukuba bathoxise kwisilwanyana.
I-Sloths isebenzisa iinwele zabo ezide, ezininzi ezimnyama okanye ezibomvu, ngokuqhelekileyo zihlanganiswe nge-blue algae ngexesha lezimvula, njengemibala yokukhusela. Iinwele zabo zibafihla zisuka kwisisu ukuya emva, ziwa phezu kwazo njengoko zixhomekeke.
Abaxhasi baquka iinyoka ezinkulu, i-harpy nezinye iintaka, iigagu kunye ne-ocelots.
Izitifiketi zaseMzantsi Melika zineentloko ezimfutshane zentlanzi, iintsuku ezifutshane kunye neendlebe ezincinci. Jonga ezi zithombe. Ngaphandle kwenani leenzwane zangaphambili, kukho ukungafani phakathi kweentonga ezimbini kunye neentonga ezintathu:
- Iintlanzi ezimbini ezinamazinyo zineentandathu ezisixhenxe okanye ezisixhenxe ze-vertebra
- Iintlanzi ezimbini ezinamazinyo azikho imisila. Imilenze yabo yangaphambili nangemuva ibukhulu obufanayo
- Iintala ezinamacala amabini unentamo emfutshane, amehlo amakhulu kwaye ihamba rhoqo phakathi kwemithi
- Iintlanzi ezimbini zomlenze akulula ukuhamba. Basebenzisa amazinyo abo e-canine ekuhlaleni.
- Iintlanzi ezintathu zontonga zineentsimbi ezithoba
- Iintlanzi ezintathu zentonga zinomsila omncinci. Iinyawo zabo zangaphambili zide kunezo zangaphambili
- Izintambo ezinamathathu zineentamo ezimfutshane kunye neenyawo ezincinci
- Iintlanzi zintathu ezintathu zinobubele, okwenza kube lula ukuba bathabathe izilwanyana. Ngoku bahlala kwiindawo zengozi ezisengozini.
Ngoxinzelelo olusisigxina ngumntu kunye nomatshini emahlathini emvula eMzantsi Melika, i-slots, njengamanye amaninzi asezidlangalaleni ezisehlathini, zisengozini.
