Ukuphonononga amazinyo olwandle: Mangaphi amazinyo omnenga?

Makhe sihlolisise iimfihlelo zobomi baselwandle obumangalisayo kwaye sihlolisise i-anatomy emangalisayo yomnenga omkhulu. Xa sisenza umfanekiso womnenga, sisoloko sicinga ngobukhulu bawo, amandla awo okwenza izandi ezichukumisayo, nobuchule bawo bokudubulela esibhakabhakeni ngaphambi kokuba ungene ngaphantsi kwamaza. Kodwa ngaba wakha wazibuza ukuba mangaphi amazinyo omnenga? Esi sihloko sinomdla sivumela ukuba siqonde ngakumbi iyantlukwano kunye nokuguquguquka kwezilwanyana.

Ingaba yonke iminenga inamazinyo?

Ngaphambi kokuba singene ixabiso kwamazinyo, kubalulekile ukucacisa ukuba asiyiyo yonke iminenga enamazinyo. Iminenga yohlulwe yangamacandelo amabini: i-mysticetes kunye ne-odontocetes. I-Mysticetes, okanye i-baleen whales efana ne-blue whales, ayinamazinyo, kodwa ine-baleen eyenziwe nge-keratin bristles evumela ukuba bahluze ukutya kwabo emanzini. Kwelinye icala, ii-odontocetes, eziquka i-orcas okanye iminenga ebulalayo, zinabo.

Iminenga kunye namazinyo awo awodwa

Amazinyo omnenga ahlukile kuninzi lwezinye izilwanyana ezanyisayo. Endaweni yokuba iintlobo ezahlukeneyo amazinyo - incisors, canines, premolars, kunye molars - the Iminenga yeOdontocete inothotho lwamazinyo afana necone ezihambelanayo emlonyeni wakho wonke. La mazinyo, adla ngokuba phakathi kwama-40 nama-50, enzelwe ukubamba nokubamba ixhoba, kungekhona ukuhlafuna.

Ukubala amazinyo omnenga

Inani lamazinyo omnenga analo liyahluka ngokuxhomekeke kwiintlobo zawo. Njengomgaqo jikelele:

• I-Orcas, ekwabizwa ngokuba yiminenga ebulalayo, ihlala inamazinyo angama-40 ukuya kuma-56 ewonke.
• Iminenga emfutshane yePacific inamazinyo amancinane amalunga ne-150 ukuya kwi-170.
• Iminenga yaseBeluga, edume “ngokudumba” kwayo “imelon” phambi kweentloko zayo, inamazinyo angama-34 ukuya kwangama-40.

Ukuzalwa kunye noTshintsho lwezinyo kwiminenga

Las Iminenga, njengezinye izilwanyana ezanyisayo, izalwa ingenamazinyo. Ezi ziqalisa ukuntshula njengoko umnenga ukhula, nangona kunjalo, ngokungafaniyo nabantu, xa umnenga odontocete uphuma elinye lamazinyo awo, awutshintshwa. Kuphononongo olwenziwa ngeminenga ebulalayo, kwafunyaniswa ukuba ezi zigebenga zaselwandle zihlala zigula zizifo zamazinyo ngenxa yokunxiba okanye ukophuka.

Ukudlala Indima Ebalulekileyo kuBomi beMinenga

Enokuba abambe aze akugcine ukutya kwawo, okanye anxibelelane neqela lawo, amazinyo anendima ebalulekileyo kubomi baselwandle beminenga. Nangona zisenokungabi naxabiso lincomekayo, izinyo ngalinye libalulekile ukuze ziqhubeke ziphila. Njengabagcini bendalo, ngumsebenzi wethu ukukhusela ezi zidalwa zikhulu kunye neendawo zazo zokuhlala ukuze nezizukulwana ezizayo zibe nokuzixabisa.
