Iiminenga: IiNgxilimbela zaseLwandlekazi

Iiminenga ziphakathi kwezilwanyana ezinkulu nezibalaseleyo emhlabeni. Ezi zilwanyana zasolwandle zihlala kwiilwandle kwihlabathi liphela, ukusuka emanzini afudumeleyo ashushu ukuya kwiilwandle ezibandayo ezijikeleze iingongoma.

Ubomi Obungaphantsi Komphezulu

Nangona imikhomo ichitha ubomi bayo emanzini, iphefumla umoya ngemingxuma ephezu kweentloko zayo. Kufuneka ibuyele rhoqo phezu komhlaba ukuze iphefumle ngaphambi kokuba iphinde intywile ifuna ukutya okanye ihambe elwandle.

Iiminenga zinegazi elifudumeleyo, zizala amathole aphilayo, kwaye zincancisa amathole azo ngobisi. Umaleko omkhulu wamafutha abizwa ngokuba yi-blubber uyawanceda ekukhuseleni emanzini abandayo kwaye agcine amandla ngexesha lokufuduka ixesha elide.

Amaqela amabini aphambili

Iiminenga ngokubanzi zahlulwe zibe ziiminenga ze-baleen kunye neeminenga ezinezinyo. Iiminenga ze-Baleen zihluza izilwanyana ezincinci emanzini zisebenzisa iipleyiti eziguquguqukayo ezingaphakathi emlonyeni wazo. Eli qela liquka iiminenga eziluhlaza okwesibhakabhaka, iiminenga ezineempundu, kunye neeminenga ezingwevu.

Iiminenga ezinamazinyo zisebenzisa amazinyo ukubamba iintlanzi, i-squid, kunye nezinye izilwanyana. Uninzi lwazo lukwasebenzisa i-echolocation, luvelisa izandi kwaye lumamele i-echoes ezibuyayo ukuze luqonde indawo ezikuyo. Iiminenga zesidoda, ii-belugas, kunye nee-orcas zeli qela.

Umnenga oBlue

I-blue whale sesona silwanyana sikhulu esaziwayo esakha saphila. Umntu omdala unokukhula ixesha elide kunebhasi yasedolophini kwaye unobunzima obungaphezulu kweetoni ezilikhulu. Nangona inkulu kakhulu, itya kakhulu ii-crustaceans ezincinci ezibizwa ngokuba yi-krill.

Unxibelelwano kunye nokuFuduka

Iminenga inxibelelana ngokusebenzisa ukucofa, iimpempe, iipulse, kunye neengoma ezintsonkothileyo. Ezinye izandi zinokuhamba imigama emide phantsi kwamanzi. Iminenga ye-humpback idume kakhulu ngeengoma zayo ezinde, ezineepateni.

Iintlobo ezininzi zihamba amawaka eekhilomitha minyaka le. Zidla ngokutya emanzini abandayo natyebileyo kwizakhamzimba ngaphambi kokuba ziye kwiindawo ezifudumeleyo apho zidibana khona zize zizale.

Ukukhusela iiminenga

Ukuzingela ngorhwebo kwakukhe kwabangela ukwehla okukhulu kwenani leeminenga ezininzi. Namhlanje, iminenga ikwajongene nezisongelo ezivela kwizixhobo zokuloba, ukungqubana kweenqanawa, ingxolo engaphantsi kwamanzi, ungcoliseko, kunye notshintsho kwiinkqubo zendalo zaselwandle.

Iinkqubo zolondolozo lwendalo, iindlela zokuloba ezikhuselekileyo, iindawo zokuhlala ezikhuselweyo, kunye nentsebenziswano yamazwe ngamazwe zinokunceda ukuba iinkobe zibuyele esiqhelweni. Ukukhusela iinkobe kukwaxhasa ulwandle olusempilweni kuba ezi zilwanyana zidlala indima ebalulekileyo kwiindlela zokutya zaselwandle kunye nemijikelo yezakhamzimba.
