Umkhomo i-humpback noma i-humpback whale - ungowomndeni wakwa-minke futhi wenza izinhlobo zegama elifanayo. Ngeshwa, muva nje isibalo salezi zinhlobo zezilwane sehle saya emikhawulweni ebucayi, ngakho-ke sifakiwe encwadini ebomvu. Lesi simo sezindaba singenxa yemiphumela emibi ngokwedlulele yemisebenzi yabantu - ukuqothulwa kwabantu abaningi ngezinhloso zezimboni kanye nokuwohloka kwezimo zokuphila kuholele emiphumeleni emibi kangaka.
Imikhomo ebizwa ngokuthi i-humpback imaphakathi kwabamele izilwane zasendulo ezedlula zonke, okuqinisekiswa yimiphumela yezifundo ezenziwa - kutholakala ukuthi isineminyaka engaphezu kwemihlanu ubudala. Amarekhodi okuqala alesi silwane asukela ku-1756. Empeleni-ke waba negama lakhe - ngenxa yesimo se-dorsal fin nendlela yokubhukuda eyinqaba.
Ngenxa yokubukeka kwayo, cishe akunakwenzeka ukudidanisa i-humpback nezinye izinhlobo zemikhomo. Ngokumangazayo, kepha kulokhu, abesifazane bangaphezu kwabesilisa. Ubude babamele lolu hlobo lwezilwane buhluka kusuka kumamitha ayi-13.9 kuye kwayi-14.5. Abesilisa kuyaqabukela bekhula bafike kubude obungamamitha ayi-13.5. Isisindo esimaphakathi sabo bobabili abesilisa nabesifazane singamathani angama-30. Ngasikhathi sinye, cishe amathani ayi-7 abalwa ngamafutha kuphela.
Kumele kuqashelwe ukuthi phakathi kwabo bonke abamele ama-cetaceans, kuphela imikhomo nemikhomo eluhlaza okwesibhakabhaka ehlukile kuleli nani lamafutha angaphansi.
Indawo yokuhlala
Ngaphambili, ngisho nangesikhathi senqwaba yabantu bayo, umkhomo i-humpback wawutholakala cishe kuzo zonke izilwandle nolwandle. Izinombolo ezinkulu kunazo zonke zazisezilwandle zaseMedithera naseBaltic. Ngobulungiswa, kufanele kuqashelwe ukuthi yize isibalo sezingqinamba sehlile, basakhetha indawo yokuhlala engahleliwe - abantu bangatholakala bobabili ezilwandle nasolwandle.
Ngakho-ke, imihlambi emibili emikhulu ihlala eNyakatho ye-Atlantic. Emanzini e-Antarctic yaseningizimu yezwe, kunezikole ezinhlanu ezinkulu ze-humpbacks, ezishintsha indawo yazo ngezikhathi ezithile, kepha azisuki kude "nendawo yazo yokuhlala unomphela". Futhi kwatholwa isibalo esincane e-Indian Ocean.
Ngokuqondene nendawo yaseRussia, i-humpback ingatholakala eBering, Chukchi, Okhotsk naseLwandle lwaseJapan. Kuyiqiniso, inani labo lapha lincane, kepha bangaphansi kokuvikelwa okuqinile.
Indlela Yokuphila
Yize iqiniso lokuthi imikhomo i-humpback yakha imihlambi emikhulu, ngaphakathi isathanda ukuqhubeka nokuphila impilo eyodwa. Okuhlukile ngabesifazane, abangaze bashiye amaphuphu abo.
Ekuziphatheni kwabo, afana ncamashi namahlengethwa - ayadlala impela, angenza izigaxa ze-acrobatic ezingakaze zibonwe futhi angabi nankinga ngokuqhuma, avula ama-torpedoes amanzi ngaphezu kobuso bamanzi obude obukhulu nje.
Imikhomo yama-humpback ayinankinga nokwazi abantu, yize bekungumsebenzi wabo oholele ekwehleni kwamanani. Ngaphezulu kwamanzi, zingatholakala kaningi, futhi abantu ngabodwana bangahamba nomkhumbi isikhathi eside.
Ukudla
Kuyaphawuleka ukuthi ebusika, i-humpback cishe ayidli. Umane usebenzisa amasheya anqwabelene ehlobo. Ngakho-ke, ebusika, i-humpback ingalahlekelwa kufika ku-30% wobukhulu bayo.
Njengemikhomo eminingi, imikhomo idla ngokutholakala olwandle noma ekujuleni kolwandle - ama-crustaceans, izinhlanzi ezincane ezifunda isikole. Ngokwehlukana, kufanele kuthiwe ngezinhlanzi - i-humpback ithanda i-saury, i-cod, i-herring, i-mackerel, i-Arctic cod, ama-anchovies. Uma ukuzingela kuphumelele, khona-ke kufika ku-600 kilograms yezinhlanzi inganqwabelana esiswini somkhomo.
Umkhomo i-humpback, ngeshwa, usengcupheni yokuqothulwa. Ngakho-ke, izindawo ahlala kuzo zivikelwe ngokuqinile. Mhlawumbe lezi zinyathelo zizosiza ukubuyisa inani le-humpback.
