Imikhomo kulula ukuyibona ngenxa yobukhulu bayo, kodwa ziningi izici zalezi zidalwa ezaziwa kancane. Ukuze siqonde ukuthi uyini umkhomo, ngale kobukhulu bawo, kumelwe sihlole isayensi yezinto eziphilayo, indlela oziphatha ngayo, indlela odla ngayo, indawo ohlala kuyo, namanye amaqiniso athakazelisayo ngawo.
I-Anatomy kanye ne-Physiology ye-Whales
Imikhomo inemizimba emikhulu, emide elungele ukuphila olwandle. Bahlukaniswa ngamaqembu amabili: imikhomo ye-baleen kanye nemikhomo enamazinyo. Abokuqala basebenzisa lezi intshebe ukuhlunga izinto eziphilayo ezincane emanzini, kuyilapho lezi zokugcina zisebenzisa amazinyo ukubamba inyamazane.
Ubukhulu bemikhomo buhluka kakhulu. I-blue whale, isilwane esikhulu kunazo zonke esake saba khona, singafinyelela ubude obungamamitha angu-30 futhi sibe nesisindo esingamathani angu-200. Ngakolunye uhlangothi, umkhomo i-Beluga awumkhulu kakhulu kunehlengethwa.
Ukuziphatha komkhomo
Ukuziphatha komkhomo kuyinkimbinkimbi kakhulu futhi kucebile ngemininingwane. I imikhomo enamazinyo Ngokuvamile bangabantu abaningi emphakathini futhi baziwa ngokuziphatha kwabo kokudlala. Izinhlobo eziningi zaziwa ngokugxuma kwazo okumangalisayo emanzini, okubizwa ngokuthi izikhala.
Ngakolunye uhlangothi, imikhomo ye-baleen Zijwayele ukuba zodwa kakhulu noma zihambe ngamaqembu amancane. Kodwa-ke, le mikhomo futhi inokuziphatha okuthakazelisayo, njengokwenza "ama-bubble amanetha" ukuze ubambe i-krill.
Ukudla komkhomo
Imikhomo inokudla okuhlukahlukene okuncike ezinhlotsheni zayo, ubukhulu kanye nendawo yokuhlala. Eminye, njengemikhomo eluhlaza okwesibhakabhaka kanye ne-fin, idla izinto eziphilayo ezincane njenge-krill nezimfanzi. Basebenzisa izintshebe zabo ukuhlunga lezi zinambuzane ezincane emanzini.
Ngakolunye uhlangothi, imikhomo enamazinyo, njenge-orcas, idla izinhlanzi nezinye izilwane ezincelisayo zasolwandle. Ngokwesibonelo, ama-Orcas aziwa ngekhono lawo lokuzingela izimvu zamanzi ngisho neminye imikhomo.
I-Whale Habitat
Imikhomo itholakala kuzo zonke izilwandle zomhlaba, kusukela emanzini ashisayo ashisayo kuya olwandle olubandayo olubandayo. Ezinye izinhlobo zezilwane, ezinjengomkhomo ompunga kanye ne-humpback whale, zifuduka ngendlela emangalisayo izinkulungwane zamakhilomitha unyaka ngamunye ukuze zondle futhi zizalane.
Eminye, njenge-beluga whale noma i-right whale, inomngcele olinganiselwe futhi itholakala ikakhulukazi ezindaweni ezithile ze-Arctic noma eNyakatho ye-Atlantic ngokulandelana kwazo.
Ilukuluku mayelana nemikhomo
- Imikhomo ingezinye zezilwane eziphila isikhathi eside kakhulu emhlabeni. Kunenkolelo yokuthi eminye imikhomo yase-Arctic ingaphila iminyaka engaba ngu-200.
- Imikhomo inolimi lwayo. Ingoma ye-humpback whale ingenye yemisindo eyinkimbinkimbi kakhulu ekhishwa isilwane.
- Imikhomo inesandla empilweni yemvelo yasolwandle. Lapho umkhomo ufa futhi umzimba wawo ucwila olwandle, unikeza inqwaba yezinto eziphilayo ezingaphansi kolwandle ukudla.
Ekugcineni, imikhomo iyizidalwa ezithakazelisayo nezibalulekile olwandle lwethu. Njengezinye zezixhumanisi eziphakeme kakhulu ochungechungeni lokudla kwasolwandle, zidlala indima ebalulekile empilweni yemvelo yasolwandle. Ukuvikelwa nokongiwa kwazo kubalulekile empilweni yezilwandle zethu.
