Isilwane sasolwandle esikhulu kunazo zonke emhlabeni Ingafinyelela kumamitha angama-30 ubude futhi ibe nesisindo esingaphezu kwamathani angama-200. Lokho kwenza lesi silwane singagcini nje ngokuba esikhulu kunazo zonke kodwa futhi sibe esinda kakhulu olwandle.
Uma ufuna ukuthola ukuthi siyini lesi silwane, ungaphuthelwa yisihloko esisilungiselele ngaso, futhi kuphi, ngaphezu kwalokho, Sizokhuluma ngokuthi yiziphi izilwane ezinkulu kunazo zonke emhlabeni.
Isilwane sasolwandle esikhulu kunazo zonke emhlabeni
Abaningi bangase bangamangali lapho bezwa ukuthi isilwane sasolwandle esikhulu kunazo zonke emhlabeni umkhomo. Injalo umkhomo oluhlaza okwesibhakabhaka (Balaenoptera musculus). Singasho ngakho ukuthi iyisilwane esikhulu kunazo zonke, hhayi olwandle kuphela kodwa kuyo yonke iplanethi enguMhlaba. Ubude bayo obujwayelekile buphakathi kwamamitha angama-24 no-27 kodwa kutholwe izibonelo ezifinyelele kumamitha angama-30. Ukuze uthole umbono wobukhulu bemikhomo eluhlaza okwesibhakabhaka, Ubukhulu bayo bukhulu kunobendiza yezohwebo nolimi lwayo lungaba nesisindo esifanayo nesendlovu, okungesinye sezilwane ezinkulu kunazo zonke emhlabeni.
Naphezu kokuba nobukhulu obumangalisayo, imikhomo eluhlaza okwesibhakabhaka ine- umlingiswa onobungane futhi onokuthula. Bangabonakala bebhukuda ngamaqembu emindeni noma ngezinye izikhathi bebodwa befuna ukudla. Ingoma yabo, ngokungangabazeki, ingesinye sezici zolwandlekazi, ezinezandiso ezizwakala kumakhulu amakhilomitha ukusuka kude.
Umkhomo oluhlaza kanye nomlando wawo emhlabeni
Imikhomo eluhlaza okwesibhakabhaka ibihlala olwandle loMhlaba izigidi zeminyaka, lapho okhokho babo bevela ezilwaneni ezincelisayo zasemhlabeni baya ezincelisayo zasemanzini. Kukholakala ukuthi imvelaphi ye-blue whale, isilwane savela ukuze sijwayelane nokuphila olwandle, ngokuba, kokubili ngenxa yobukhulu nombala wayo, esinye sezilwane ezihlaba umxhwele kakhulu olwandle.
Unjani umkhomo oluhlaza?
I-blue whale isilwane esincelisayo sasolwandle esitholakala kuzo zonke izilwandle zomhlaba futhi sidla ama-crustaceans amancane nezinhlanzi. Yake yaba sengozini enkulu yokushabalala ngenxa yokuzingela ngokungakhethi ukuhweba kwemikhiqizo etholakala kuyo. I Imikhomo Zibalulekile ekugcineni ibhalansi ye-ecosystem yasolwandle. Ungafunda kabanzi mayelana ne- izingozi ezibhekene nemikhomo Njengamanje.
Ukudla
Phakathi naleyo minyaka elinganiselwa ezigidini ezingu-20 lapho imikhomo ihamba olwandle, izinikele ekuzingeleni ukudla. Okwakhe Ukudla kusekelwe ku-crustacean encane ebizwa ngokuthi i-krill, nakuba ziphinde zidle izinhlanzi ezincane kanye nama-squid. Ukuze babambe lezi zisulu benza lokho okwaziwa ngokuthi "ukuphakela isihlungi", Imikhomo eluhlaza okwesibhakabhaka itshuza emanzini ajulile futhi ibhukude ivule imilomo, iqoqa amanzi amaningi lapho lezi zilwane zikhona. Bese ivala umlomo wayo ikhiphe amanzi nge-baleen yayo ukuze igcine ukudla. Ngalolu hlobo lokuzingela, badla amathani angu-4 okudla ngosuku. Nakuba kuyisilwane esikhulu kunazo zonke futhi esisinda kunazo zonke, sibhukuda ngesivinini esikhulu, okwenza sikwazi ukubamba konke lokhu kudla. Uma ufuna ukufunda kabanzi mayelana nokudla kwalezi ziqhwaga, bheka isihloko esithi lokho okudliwa yimikhomo.
Ukuzingela
Kuwo wonke umlando, umkhomo ubulokhu uzingelwa kakhulu umuntu. Phakathi nekhulu le-19 nelama-20, Bashushiswa kakhulu ukuze bathole inyama, uwoyela neminye imikhiqizo. Ngenxa yalokho, inani lama-specimens lancipha kakhulu. Ukuze kuvinjelwe lesi simo ukuba sibe sibi kakhulu, ngo-1960 ukuzingela lezi zilwane kwenqatshelwe. Yini enye, namuhla, Imikhomo eluhlaza okwesibhakabhaka ivikelwe yimithetho kanye nezivumelwano zamazwe ngamazwe, ngakho inani lezibonelo liye landa kakhulu kwezinye izindawo.
Kuyiqiniso futhi ukuthi imikhomo eluhlaza okwesibhakabhaka Abekho engozini ngokuphelele, njengoba kusenezinsongo ezisongela ukuphila kwabo, njengokungcoliswa kolwandle, ukushintsha kwesimo sezulu, ngisho nemikhumbi eshayisana nakho. Ngaphezu kwalokho, kuye kwasungulwa izindawo ezivikelwe zasolwandle ukuze lezi zilwane zibe nendawo ephephile olwandle. Lezi zindawo ezihlala emanzini zilinganiselwe izinto ezenziwa abantu ukuze kulondolozwe imikhomo nezinye izilwane esezisengozini. Ukuze uthole ulwazi olwengeziwe mayelana nemithetho evikela lezi zidalwa, ungavakashela iwebhusayithi izinhlobo zemikhomo ekhona
Ukubaluleka kwawo emhlabeni wasolwandle
Imikhomo ibalulekile ekugcineni i-ecosystem yasolwandle ngezizathu ezahlukene. Okokuqala nje, yilawo alawula noma alawula inani lama-krill (ukudla kwawo okuyinhloko). Uma benyamalala, inani labantu abangama-krill belingeke lilawuleke futhi lithinte i-ecosystem. Ngakolunye uhlangothi, ukusetshenziswa kwe-krill kubangela ukuthi bakhiphe inani elikhulu lezakhi ezibalulekile ngendle yabo ukuze inani elikhulu lezitshalo zasolwandle kanye ne-phytoplankton likhule. Konke lokhu kuyabenza isilwane esiyisihluthulelo seketango lokudla olwandle.
Njengokungathi lokhu okungenhla akwanele, nomthelela emjikelezweni wekhabhoni njengoba bemunca isikhutha esiningi emkhathini futhi basigcine ezicutshini zabo. Lapho sifa, leyo carbon idlulela olwandle. Kubalulekile ukuqonda ukuxhumana kwalezi zilwane ezincelisayo nemvelo yasolwandle ukwazisa indima yazo emvelweni, isihloko okukhulunywa ngaso ngokujulile esihlokweni esithi. izilwane ezincelisayo zasolwandle.
Izilwane eziyi-10 ezinkulu kunazo zonke emhlabeni
El Indawo yokuqala esesiyazi ukuthi igcwele umkhomo omkhulu oluhlaza okwesibhakabhaka, kodwa ezinye izilwane ziyalilandela, nakuba sibubona kude ubude bazo.
- 2. Whale shark engafinyelela kumamitha ayi-18 ubude.
- 3. Elephant seal ngamamitha angu-8 ubude.
- 4. Indlovu yase-Afrika efinyelela ku-7 metres.
- 5. Indlulamithi engafinyelela ku-6 amamitha.
- 6. ingwenya yasolwandle ngamamitha angu-6 ubude.
- 7. Ushaka Omhlophe Ingafinyelela kumamitha ayisi-6 futhi.
- 8. Ibhere elimhlophe Ingafinyelela kumamitha angu-3 ukuphakama.
- 9. Ibhere le-Kodiak Ingakwazi futhi ukukala amamitha ama-3.
- 10. Ekugcineni, I-grizzly Ikhula ibe ngamamitha angu-2,8 ukuphakama.
Kuwo wonke, imikhomo eluhlaza okwesibhakabhaka iyaqhubeka nokuba umbukwane kubantu, banjalo izidalwa ezithakazelisayo hambani ngeqembu noma nodwa. Bakhanga ngobukhulu bazo, ingoma yabo, indlela yabo yokubhukuda, nokuziphatha kwabo, kangangokuthi baye baba olunye lwezimpawu eziwuphawu lwezilwane zasolwandle. Baphinde a isikhumbuzo sokuhlukahluka okukhulu esingakuthola emhlabeni kanye nokubaluleka kokulondoloza zonke izidalwa ukuze kugcinwe lokho kuhlukahluka okufanayo.
