Isingeniso: Umhlaba Othakazelisayo Wemvelo Yezilwane
Umbuso wezilwane uwumhlaba ohlukahlukene futhi oyinkimbinkimbi ongahluleki neze ukusimangaza ngezici zawo eziyingqayizivele nokuzivumelanisa nezimo. Kusukela ezinambuzaneni ezincane kakhulu kuya ezilwaneni ezincelisayo ezinkulu kunazo zonke, izilwane ziye zavela ukuze ziphile ezindaweni zazo ngokuzivumelanisa nezimo ezihlukahlukene zomzimba nokuziphatha. Esinye sezici ezithakazelisa kakhulu zokwakheka kwezilwane ubukhulu nengxenye yezingxenye zabo zomzimba, ikakhulukazi ikhanda.
Usayizi Wekhanda kanye Nezilinganiso Zomzimba Embusweni Wezilwane
Ezilwaneni, ubukhulu nengxenye yekhanda maqondana nomzimba iyahlukahluka kakhulu ezinhlotsheni zezilwane. Ezinye izilwane zinamakhanda amakhudlwana kunemizimba yazo, kanti ezinye zinamakhanda amancane uma kuqhathaniswa. Ubukhulu kanye nengxenye yekhanda ngokuvamile kubonisa indlela yokuphila yesilwane nendawo yokuhlala. Isibonelo, izilwane ezidla ezinye izilwane ngokuvamile zinamakhanda amakhulu kanye nemihlathi eqinile ukuze zibambe futhi zibulale inyamazane, kuyilapho izilwane ezidla uhlaza zivame ukuba namakhanda amancane nezintamo ezinde ukuze zifinyelele uhlaza.
Ukubaluleka Kosayizi Wekhanda Ekuphileni Kwezilwane
Ubukhulu nengxenye yekhanda kungaba nomthelela omkhulu ekusindeni kwesilwane. Ikhanda elikhudlwana linganikeza izinzuzo ngokuzingela, ukuzivikela, noma ukuncintisana kwabalingani. Ikhanda elincane lingavumela umnyakazo osebenza kahle kakhulu noma ukufinyelela kangcono izinsiza. Ukwengeza, ezinye izimo zekhanda zingabonisa ukuzivumelanisa nemisebenzi ethile, njengokumba, ukumba, noma ukubhukuda.
Isilwane Esinekhanda Elikhulu Ngokuphathelene Nosayizi Womzimba
Isilwane esinekhanda elikhulu kunawo wonke uma kuqhathaniswa nobukhulu bomzimba ushaka okhanda ikhanda. Isimo sekhanda likashaka we-hammerhead esiyingqayizivele, esifana nesando, sinikeza izinzuzo eziningana. Amehlo abanzi avumela ukubona ukujula okungcono kanye nenkundla yombono ebanzi, kuyilapho ukwakheka okufana nesando kunikeza ukuzinza okukhulu nokuhamba kahle emanzini. Ikhanda likashaka we-hammerhead lingaba ubude obukodwa kokuthathu bomzimba walo.
Isilwane Esinekhanda Elincane Kakhulu Esihlobene Nosayizi Womzimba
Isilwane esinekhanda elincane kakhulu elihlobene nobukhulu bomzimba yi-Etruscan shrew. Lesi silwane esincelisayo esincane, esingamasentimitha ambalwa ubude, sinekhanda elingaphansi kwengxenye eyodwa kwezintathu ubude bomzimba waso. Ikhanda elincane le-Etruscan shrew liyivumela ukuba ihambe kalula emigudwini emincane nemigodi ifuna izinambuzane nezinye izilwane ezincane.
Isiphi isilwane esinekhanda elikhulu kunomzimba waso?
Isilwane esinekhanda elikhulu kunomzimba waso yi-sunfish. I-sunfish, eyaziwa nangokuthi i-mola mola, iyinhlanzi enamathambo esinda kakhulu emhlabeni futhi ingaba nesisindo esingamakhilogremu angu-2,200. Naphezu kobukhulu bayo obukhulu, i-sunfish inomzimba omncane uma iqhathaniswa nekhanda layo elikhulu, eliyindilinga. Ukuma kwekhanda eliyingqayizivele le-sunfish kucatshangwa ukuthi linikeza ukukwazi ukulawuleka kanye nokuzinza okukhulu emanzini, kanye nendawo engaphezulu yokunamathisela imisipha yomhlathi enamandla ukuze iyisize icoboze inyamazane yayo.
I-Anatomy Yesilwane Esinenhloko Enkulu Ngokungalingani
Ikhanda le-sunfish elikhulu ngokungenakulinganiswa libangelwa ukuhlangana kwamathambo ogebhezi lwekhanda abe yisakhiwo esisodwa esiqinile. Umhlathi we-sunfish nawo uhlanganiswe nogebhezi lwekhanda, oluvumela ukuba lukhiqize amandla amakhulu okuluma. Isikhumba se-sunfish siwugqinsi futhi siqinile, okusiza ukuyivikela ezilwaneni ezidla ezinye nezilokazane.
Umsebenzi Wekhanda Elikhulu Endaweni Ehlala Izilwane
Inhloko enkulu ye-sunfish inikeza izinzuzo eziningana endaweni yayo. Ukuma kwe-sunfish eyisicaba, eyindilinga kuyivumela ukuba ikwazi ukumunca ukukhanya kwelanga okwengeziwe, okusiza ukulawula izinga lokushisa lomzimba wayo. Ikhanda elikhulu le-sunfish liphinde linikeze umuzwa omkhulu wokulinganisela nokuzinza emanzini, okubalulekile enhlanzini echitha isikhathi esiningi eduze kwendawo. Ngaphezu kwalokho, ikhanda elikhulu le-sunfish nemihlathi enamandla kuyivumela ukuba icoboze inyamazane yayo, ehlanganisa ikakhulukazi i-jellyfish.
Izinzuzo kanye Nobubi beNhloko Enkulu
Ikhanda elikhulu linganikeza izinzuzo eziningana esilwaneni, njengamandla amakhulu, ukuzinza, nokuqonda kwezinzwa. Kodwa-ke, ikhanda elikhulu lingabuye libe nokubi, njengokunyuka kwezindleko zamandla, ukunciphisa ukuhamba, nokuba sengozini kwezilwane ezidla ezinye.
Ezinye Izilwane Ezinezitho Zomzimba Ezingalingani
I-sunfish akusona sodwa isilwane esinezitho zomzimba ezinkulu ngokulinganayo. Ezinye izibonelo zihlanganisa ikhala ende lenyamazane, intamo ende yendlulamithi nolimi olude lukanwabu. Lezi zimo zivumela izilwane ukuthi zifinyelele kangcono ezindaweni ezithandayo zokudla noma zizivikele ezilwaneni ezidla ezinye.
Iqhaza Lezilinganiso Zomzimba Ekuguqukeni Kwezilwane
Ubukhulu nengxenye yezingxenye zomzimba, kuhlanganise nekhanda, kunendima enkulu ekuziphendukeleni kwezilwane. Njengoba izilwane zijwayela indawo yazo nendlela yokuphila, ziba nezici zomzimba nezokuziphatha ezizivumela ukuba ziphile kangcono futhi zizalane. Ngokuhamba kwesikhathi, lezi zimo zingaholela ekwakhiweni kwezinhlobo ezintsha zezilwane kanye nokushabalala kwezinye.
Isiphetho: Ukuhlukahluka Kwemvelo Yezilwane
Ubukhulu nengxenye yezingxenye zomzimba embusweni wezilwane kuhlukahluka njengezindawo nezindlela zokuphila zezakhamuzi zakhona. Kusukela ekhanda elikhulu le-sunfish kuya ekhanda elincane le-Etruscan shrew, izilwane ziye zashintsha ukujwayela okuyingqayizivele ukuze ziphile futhi ziphumelele ezindaweni zazo. Ukuqonda lezi zimo kunganikeza ukuqonda emhlabeni othakazelisayo we-anatomy yezilwane kanye nenqubo eqhubekayo yokuziphendukela kwemvelo.
