Isingeniso: Yiziphi izilwane ezingenazinwele?
Izinwele ziyisici esichazayo sezilwane eziningi, kodwa akuzona zonke izidalwa ezibusiswe ngejazi elinoboya. Ezinye izilwane azinazo izinwele ngokuphelele, kanti ezinye zinezimbotshana ezinjengamazenga, izimpaphe, noma amagobolondo. Ukuqonda ukuthi yiziphi izilwane ezingenazo izinwele kungasisiza sazise izinhlobonhlobo zezinto eziphilayo eMhlabeni.
Inhlanzi: Izilwane zasemanzini ezingenaboya
Izinhlanzi zingelinye lamaqembu ezilwane ahluke kakhulu emhlabeni, anezinhlobo ezingaphezu kuka-30,000. Naphezu kwalokhu kuhlukahluka, zonke izinhlanzi zihlanganyela isici esisodwa: azinazo izinwele. Esikhundleni salokho, banongqimba lwamafinyila amancane avikela isikhumba sabo futhi abasize bahambe emanzini ngokuphumelelayo. Ezinye izinhlanzi, njengoshaka, zinamazenga amakhulu afeza injongo efanayo.
Ama-Amphibians: Izidalwa ezincane ezingenabo uboya
Ama-Amphibians yiqembu lezilwane ezinegazi elibandayo ezivame ukuchitha ingxenye yempilo yazo emanzini futhi ingxenye emhlabathini. Leli qembu lihlanganisa amaxoxo, amaxoxo, ama-salamanders, nama-newts. Ngokungafani nezilwane ezincelisayo, izilwane eziphila emanzini nasezweni azinazo izinwele noma uboya. Esikhundleni salokho, banesikhumba esimanzi, esithambile esibasiza ukuthi babambe umoya-mpilo futhi bahlale bemanzi. Ezinye izilwane eziphila emanzini nasezweni zinamapuleti amathambo noma imigogodla esikhumbeni sazo ukuze zivikeleke.
Izilwane ezihuquzelayo: Isikhumba esinesikhumba esingenazinwele
Izilwane ezihuquzelayo zingelinye iqembu lezilwane ezinegazi elibandayo ezingenazinwele. Kunalokho, anezikali ezenziwe nge-keratin, into efanayo eyenza izinwele nezinzipho zethu. Lezi zikali zinikeza isivikelo ezilwaneni ezidla ezinye futhi zisiza izilwane ezihuquzelayo ukulawula izinga lokushisa lomzimba wazo. Ezinye izilwane ezihuquzelayo, njengezinyoka, zichitha amazenga azo ngezikhathi ezithile njengoba zikhula.
Izinyoni: Abangane abanezimpaphe abangenabo uboya
Izinyoni ziyizilwane ezinegazi elifudumele ezavela kuma-dinosaur. Ngokungafani nezilwane ezincelisayo, azinazo izinwele noma uboya. Kunalokho, anezimpaphe, ezenziwe ngekeratin njengamazenga ezilwane ezihuquzelayo. Izimpaphe zisiza izinyoni ukuba zindize, zilawule izinga lokushisa lomzimba wazo futhi zihehe abalingane. Izinyoni zinezinhlobo ezihlukahlukene zezimpaphe, kusukela ezimpapheni ezithambile ezifika phansi kuye kweziqinile zokundiza.
Izinambuzane: Izidalwa ezincane ezingenazinwele
Izinambuzane ziyiqembu lezilwane ezihluke kakhulu eMhlabeni, ezinezinhlobo ezingaphezu kwesigidi ezaziwayo. Ngokungafani nezilwane ezincelisayo, azinazo izinwele noma uboya. Kunalokho, bane-exoskeleton eqinile eyenziwe nge-chitin, into eqinile, evikelayo. Izinambuzane zinemilenze ehlangene, amaphiko nezimpondo, ezizisiza ukuba zinyakaze futhi zizwe indawo ezikuyo.
Mollusks: Izilwane ezinomzimba othambile ezingenazinwele
I-mollusk iyiqembu lezilwane ezihlukahlukene ezihlanganisa iminenke, ama-clams, ama-octopus, nama-squid. Ngokungafani nezilwane ezincelisayo, azinazo izinwele noma uboya. Kunalokho, anemizimba ethambile, enenyama evikelwe igobolondo eliqinile noma alikho nhlobo. Amanye ama-mollusk, njengama-octopus, angashintsha umbala nokuthungwa kwesikhumba sazo ukuze ahlangane nendawo ezizungezile.
Ama-Arachnids: Izidalwa ezinwabuzelayo ezingenabo uboya
Ama-arachnids yiqembu lezilwane ezinemilenze eyisishiyagalombili ezihlanganisa izicabucabu, ofezela kanye nemikhaza. Ngokungafani nezilwane ezincelisayo, azinazo izinwele noma uboya. Kunalokho, bane-exoskeleton eqinile eyenziwe nge-chitin, njengezinambuzane. Amanye ama-arachnid, njengezicabucabu, asonta usilika ukuze enze amawebu noma asonge inyamazane yawo.
I-Crustaceans: Izilwane ezinamagobolondo aqinile ezingenazinwele
Ama-crustaceans yiqembu lezilwane ezihlanganisa izinkalankala, ama-lobster, nezimfanzi. Ngokungafani nezilwane ezincelisayo, azinazo izinwele noma uboya. Esikhundleni salokho, bane-exoskeleton eqinile eyenziwe nge-chitin, njengezinambuzane nama-arachnids. Amanye ama-crustaceans, njengezinkalankala, angakwazi ukuvuselela izitho ezilahlekile.
Ama-Echinoderms: Izidalwa ezinamaphiko ezingenazinwele
I-Echinoderms iyiqembu lezilwane ezihlanganisa izinkanyezi zasolwandle, ama-urchin olwandle, namakhukhamba olwandle. Ngokungafani nezilwane ezincelisayo, azinazo izinwele noma uboya. Esikhundleni salokho, bane-exoskeleton eqinile, e-spiny evikela imizimba yabo ethambile. Amanye ama-echinoderm, njengezinkanyezi zasolwandle, angakwazi ukuvuselela izingalo ezilahlekile.
Izikelemu: Izilwane ezinyakazayo ezingenaboya
Izikelemu ziyiqembu lezilwane ezihlukene ezihlanganisa iminyundu, iminyundu, namaflatworm. Ngokungafani nezilwane ezincelisayo, azinazo izinwele noma uboya. Kunalokho, zinemizimba ethambile, ezacile ezisiza ukuba zihambe enhlabathini, emanzini, noma kwezinye izindawo. Ezinye izikelemu, njengama-leeches, zinamasucker noma imihlathi ukuze zizisize zidle.
Isiphetho: Izinhlobonhlobo zezilwane ezingenazinwele
Izinwele zingase zibe isici esichazayo sezilwane eziningi, kodwa akudingekile ukuze ziphile. Izilwane eziningi ziye zashintsha ezinye izembozo, njengezikali, izimpaphe, noma amagobolondo, asebenza imisebenzi efanayo. Ngokuqonda ukuthi yiziphi izilwane ezingenazo izinwele, singabonga ngokuhlukahluka okumangalisayo kwempilo eMhlabeni.
