Zonke izilwane zidinga ukulala noma okungenani zifake isimo sokuphumula evumela ukuhlanganisa okuhlangenwe nakho okuphilwa ngesikhathi sokuvuka nokuthi umzimba ungaphumula. Akuzona zonke izilwane ezilala ngendlela efanayo, futhi azidingi ukulala inani elifanayo lamahora.
Isibonelo, izilwane ezizingelayo, njengezilwane ezinezinyawo, zilala isikhathi esifushane kakhulu futhi zingalala nokuma zimile. Nokho, izilwane ezidla ezinye zingalala amahora amaningi. Abalali ngokujule njalo, kepha basesimweni sokulala, njengoba kunjalo ngamakati.
Izilwane ezihlala emanzini, njengezinhlanzi, nazo zidinga ukungena kulesi simo sokulala, kodwa kanjani ukulala kwezinhlanzi? Khumbula ukuthi uma inhlanzi ilele njengezilwane ezincelisayo zomhlaba, ingadonswa yimisinga futhi igcine idliwe. Ukuthola kabanzi mayelana nokuthi izinhlanzi zilala kanjani, ungaphuthelwa le ndatshana yePeritoAnimal, njengoba sizochaza ukuthi yiziphi izinhlanzi ezisetshenziswayo nokuthi zilala kanjani. Ngaphezu kwalokho, sizobhekana nezinkinga ezifana nokuthi izinhlanzi zilala ebusuku noma ilala amahora amangaki inhlanzi.
Ukulala kwezinhlanzi? Ukuguquka phakathi kokulala nokuvuka
Eminyakeni embalwa eyedlule, kwaboniswa ukuthi indawo ephakathi kokulala nokuphaphama, okungukuthi, phakathi kwesimo sokulala nokuvuka, iqondiswa izinzwa etholakala esifundeni sobuchopho esibizwa hypothalamus. La ma-neuron akhipha into ebizwa nge-hypocretin futhi ukushoda kwayo kukhiqiza i-narcolepsy.
Ocwaningweni lwakamuva, kwaboniswa ukuthi izinhlanzi nazo zinayo le nucleus ye-neuronal, ngakho-ke singakusho lokho izinhlanzi zilele noma ukuthi okungenani banamathuluzi okukwenza.
Izinhlanzi zokulala: izimpawu
Okokuqala nje, kunzima ukunquma ukulala ezinhlanzini. Ezilwaneni ezincelisayo nasezinyonini, kusetshenziswa amasu afana ne-electroencephalogram, kodwa lawa ahlobene ne-cortex yobuchopho, isakhiwo esingekho ezinhlanzini. Futhi, ukwenza i-encephalogram endaweni yasemanzini akunakwenzeka. Ukubona uma izinhlanzi zilele, kuyadingeka ukuthi unake izindlela ezithile zokuziphatha, njenge:
- Ukungasebenzi isikhathi eside. Lapho inhlanzi ihlala inganyakazi isikhathi eside, ezansi kolwandle, ngokwesibonelo, kungenxa yokuthi ilele.
- Ukusetshenziswa kwesiphephelo. Izinhlanzi, lapho ziphumule, zifuna indawo yokukhosela noma indawo efihlekile ukuzivikela ngenkathi zilele. Isibonelo, umhume omncane, idwala, ezinye izimila zasolwandle, phakathi kwabanye.
- Ukwehla kobuzwe. Lapho zilele, izinhlanzi zinciphisa ukuzwela kwazo ezintweni ezikhuthazayo, ngakho-ke aziphenduli ezenzakalweni ezenzeka ngakubo ngaphandle kokuthi zibonakale kakhulu.
Ezimweni eziningi, izinhlanzi zehlisa izinga lazo lokunciphisa umzimba, zehlisa izinga lokushaya kwenhliziyo nokuphefumula. Kukho konke lokhu, noma singaboni i izinhlanzi zokulala njengoba sibona ezinye izilwane ezifuywayo, lokho akusho ukuthi inhlanzi ayilali.
Inhlanzi ilala nini?
Omunye umbuzo ongaphakama lapho uzama ukuqonda ukuthi izinhlanzi zilala kanjani lapho zenza lo msebenzi. Izinhlanzi, njengezinye izinto eziningi eziphilayo, zingaba izilwane ubusuku, imini noma ukuhwalala futhi, kuya ngemvelo, bazolala ngasikhathi sinye.
Isibonelo, i-tilapia yaseMozambique (Oreochromis mossambicus) ulele ebusuku, ehlela ezansi, anciphisa izinga lokuphefumula kwakhe futhi enze amehlo akhe angasebenzi kahle. Ngokuphambene nalokho, i-catfish enamakhanda ansundu (Ictalurus nebulosus) yizilwane zasebusuku futhi zichitha usuku endaweni yokukhosela nazo zonke izimpiko zazo zikhululekile, okungukuthi, zikhululekile. Abaphenduli emsindweni noma ekuthintaneni nesikhuthazo futhi ukushaya kwabo nokuphefumula kuhamba kancane kakhulu.
I-tench (i-tinea tinea) kungenye inhlanzi yasebusuku. Lesi silwane silala emini, sisele ngezansi ngesikhathi Izinkathi zemizuzu engama-20. Ngokuvamile, izinhlanzi azilali isikhathi eside, amacala afundwe njalo ahlala imizuzu embalwa.
Futhi hlola ukuthi izinhlanzi zikhiqiza kanjani futhi kule ndatshana yePeritoAnimal.
Isilwane esilala sivule amehlo: inhlanzi
Inkolelo evamile eyandile ukuthi izinhlanzi azilali ngoba azilokothi zivale amehlo azo. Lowo mcabango awulungile. Izinhlanzi azikwazi nje ukuvala amehlo ngoba ungabi namajwabu amehlo. Ngalesi sizathu, izinhlanzi balale njalo bavule amehlo.
Kodwa-ke, ezinye izinhlobo zikashaka zinalokho okwaziwa ngokuthi ulwelwesi oluchazayo noma ijwabu leso lesithathu, esebenza ukuvikela amehlo, yize lezi zilwane nazo zingawavali ukuze alale. Ngokungafani nezinye izinhlanzi, oshaka abakwazi ukuyeka ukubhukuda ngoba uhlobo lokuphefumula abakwenzayo ludinga ukuthi bahlale behamba njalo ukuze amanzi adlule emiphefumulweni ukuze bakwazi ukuphefumula. Ngakho-ke, ngenkathi zilele, oshaka bahlala behamba, yize behamba kancane kakhulu. Izinga lokushaya kwenhliziyo yabo nezinga lokuphefumula liyancipha, njengoba kunjalo nangengqondo yabo, kepha njengezilwane ezidlayo, akudingeki bakhathazeke.
Uma ufuna ukwazi kabanzi ngezilwane zasemanzini, bheka le ndatshana ngabakwaPeritoIzilwane mayelana nokuthi amahlengethwa axhumana kanjani.
Uma ufuna ukufunda izindatshana eziningi ezifana ne- Ukulala kwezinhlanzi? incazelo nezibonelo, sincoma ukuthi ufake isigaba sethu se-Curiosities somhlaba wezilwane.
