Isingeniso: Izilwane ezingenazo izinselo
Izinselo ziqinile, zinezimpondo, futhi ziyisivikelo ezinyaweni zezilwane ezithile ezincelisayo. Banikeza ukusekela futhi basize isilwane ukuba sihambe ezindaweni ezihlukahlukene. Nokho, akuzona zonke izilwane ezinenselo. Eqinisweni, kunezinhlobo eziningi zezilwane ezikhona ngaphandle kwalezi zakhiwo. Kulesi sihloko, sizohlola izinhlobonhlobo zezilwane ezingenazinselo futhi sixoxe ngezinye zezinto ezihlukile eziye zasungulwa yilezi zilwane.
Izilwane ezincelisayo ezingenazinselo
Nakuba izilwane ezincelisayo eziningi zinezinselo, zikhona futhi eziningi ezingenawo. Ngokwesibonelo, izimfene ezinjengabantu, izimfene nezinkawu zinezandla nezinyawo ezinezinzipho esikhundleni sezinselo. Ezinye izilwane ezincelisayo ezingenazinselo zihlanganisa imikhomo, amahlengethwa, ama-porpoise, nezimvu zamanzi. Lezi zilwane ziye zavela ukuze ziphile ezindaweni ezihlala emanzini futhi sezakhe imizimba namaphiko alula esikhundleni samanqina ukuze zizisize zibhukude.
Izinyoni ezingenazo izinselo
Zonke izinyoni zinezinyawo, kodwa akuzona zonke ezinenselo. Ngokwesibonelo, izinyoni eziningi zasemanzini njengamadada, amahansi, namadada anezinyawo ezinezintambo ezilungele ukubhukuda, kuyilapho izinyoni ezidla inyama njengezinkozi, oklebe nezikhova zinezinzipho ezibukhali zokubamba inyamazane. Ezinye izinyoni ezingenazo izinselo zihlanganisa izintshe, ama-emmu, nophengwini, abaye bazijwayeza ukuphila ezweni noma emanzini.
Izilwane ezihuquzelayo ezingenazo izinselo
Izilwane ezihuquzelayo eziningi zinezinzipho noma izinzipho ezinyaweni zazo, kodwa zimbalwa kakhulu ezinezinselo. Izibonelo zifaka i-Gharial, uhlobo lwengwenya olutholakala e-India nase-Nepal, olunezinyawo ezinezintambo ezijwayele ukubhukuda. Ezinye izilwane ezihuquzelayo ezingenazo izinselo zihlanganisa izibankwa, izinyoka, nezimfudu, ezithembele emazengeni nasezinzipho ukuze zivikeleke futhi zinyakaze.
Ama-Amphibians ngaphandle kwamaHooves
Ama-Amphibians yiqembu elihlukahlukene lezilwane ezihlanganisa amaxoxo, amaxoxo, ama-salamanders, nama-newts. Nakuba zinezinyawo, ayikho neyodwa yazo enezinselo. Kunalokho, zinesikhumba esimanzi, esinamathelayo esizivumela ukuba zimunce umoya-mpilo esikhumbeni sazo. Izilwane ezihlala emanzini ziphinde zibe nolimi olude, olunamathelayo lokubamba inyamazane nemilenze eqinile yokugxuma nokubhukuda.
Izinhlanzi ezingenazo izinselo
Izinhlanzi yizilwane zasemanzini ezingenazo izinyawo nezinselo. Kunalokho, zinezimpiko ezizisiza ukuba zibhukude futhi zihambe emanzini. Izimpiko zezinhlanzi ziza ngezinhlobo nobukhulu obuhlukahlukene, okuhlanganisa amaphiko angemuva, angemuva, ne-pectoral, azivumela ukuba zilawule ukunyakaza kwazo emanzini.
Izinambuzane ezingenazo izinselo
Izinambuzane ziyiqembu elihlukahlukene lezilwane ezinemilenze eyisithupha esikhundleni sezinyawo noma izinselo. Izinambuzane zisebenzisa imilenze yazo ukuhamba, ukugxuma, nokukhuphuka. Ezinye izinambuzane, njengezimpukane nomiyane, ziye zajwayela ukundiza futhi zakha amaphiko ukuze zizisize zihambe emoyeni.
Ama-arachnids ngaphandle kwama-Hooves
Ama-arachnids yiqembu lezilwane ezihlanganisa izicabucabu, ofezela kanye nemikhaza. Zinemilenze eyisishiyagalombili esikhundleni sezinselo noma izinyawo. Ama-arachnid asebenzisa imilenze yawo ukuzingela, ukuzivikela, nokunyakaza. Amanye ama-arachnid, njengezicabucabu, aye akhiqiza izindlala zikasilika ezikhethekile ezikhiqiza ubulembu bokubamba inyamazane.
Ama-crustaceans ngaphandle kwama-Hooves
Ama-crustaceans yiqembu lezilwane ezihlanganisa izinkalankala, ama-lobster, nezimfanzi. Zinemilenze esikhundleni sezinselo futhi ziyisebenzisela ukukhasa, ukubhukuda nokubamba inyamazane. Ama-crustaceans ane-exoskeleton eqinile evikela imizimba yawo futhi ibasize ukuba bahambe ezindaweni ezihlukahlukene.
Ama-mollusk ngaphandle kwama-Hooves
Ama-mollusk yiqembu lezilwane ezihlanganisa iminenke, ama-clams, nama-squid. Azinazo izinselo noma izinyawo kodwa zisebenzisa unyawo olunemisipha ukuze zinyakaze. Amanye ama-mollusk, njenge-squid, asungule i-jet propulsion ukuze abaleke ezilwaneni ezidla ezinye.
Echinoderms ngaphandle Hooves
I-Echinoderms iyiqembu lezilwane ezihlanganisa i-starfish, ama-urchins olwandle, namakhukhamba olwandle. Azinazo izinselo noma izinyawo kodwa zisebenzisa amakhulukhulu ezinyawo zamashubhu amancane ukuze zinyakaze futhi zidlise. Ama-echinoderm ane-exoskeleton eqinile evikela imizimba yawo futhi ibasize ukuba bahambe ezindaweni ezihlukahlukene.
Isiphetho: Ukuhlukahluka Kwezilwane Ezingenayo Izinselo
Sengiphetha, kunezinhlobo eziningi zezilwane ezingenazo izinselo. Kusukela ezilwaneni ezincelisayo kuye kuma-mollusk, iqembu ngalinye lenze ukujwayela okuhlukile ukuze lizisize zinyakaze futhi ziphile endaweni yazo. Nakuba izinselo ziwusizo ezilwaneni ezithile, ukuhlukahluka kwezilwane ezingenazinselo kubonisa ukuthi ziningi izindlela zokuhamba nokuchuma ezilwaneni.
