Umnenga osemazantsi sisidalwa saselwandle esimangalisayo, uneempawu ezikhethekileyo ezinomtsalane kakhulu, ezinobukhulu obugqithisileyo bomzimba, obungaphezulu kakhulu kunabo nawuphi na umntu ophakathi. Fumana, kwaye ufunde ngakumbi ngesi silwanyana.
Descripción
Ubude bayo busuka kwi-512 ukuya kwi-intshi ezingama-590 kwinkunzi kwaye malunga ne-intshi ezingama-630 kwimazi. Ziziswa kwihlabathi kunye neemitha ezi-3 ukuya kwezi-5, ukusuka empumlweni ukuya emsileni. Ubunzima bayo buphakathi kweetoni ezingama-40 xa sele benobomi obuphuhlileyo.
Iifowuni zingabonwa, eziphakamisa iindawo zesikhumba ngaphezu kwe-5 cm ubukhulu, kunye nokuqina kwe-corneal, ebekwe kwiindawo ezahlukeneyo zentloko. Ukusasazeka, ubukhulu, kunye nemeko ye-calluses iyaguquguquka iqala ngecandelo elinye lomnenga kwaye emva koko, nangona kunjalo, azitshintshi ngokukhula.
Iicalluses zenziwa kwisigaba sosana olungekazalwa kwaye lunomthunzi omnyama, ezi calluses zibonisa inani elishinyeneyo le-amphipods ezincinci ezibizwa ngokuba zii-cymacids (iintwala zomnenga) kwaye ngamanye amaxesha zixutywa neecirripedes ezenza iicallus zibonakale zimhlophe, tyheli, orenji okanye ipinki ekhanyayo.
Ngaba banamarhamncwa endalo?
I-Southern Right Whales iyaziwa ngokuba lixhoba le Patagonian Gulls. Iingabangaba zibangela amanxeba amaninzi esikhumbeni seminenga, nangona kunjalo, iminenga ichitha amandla amaninzi isuka kwiingabangaba, nto leyo ethetha ukuba ichitha ixesha elincinane inyamekela amathole. Abaselula nabo abanamandla okumelana neminenga ebulalayo nookrebe abakhulu abamhlophe.
Ii<em>southern right whales zikwazi njani ukuziphilisa?
La ukutya komnenga wasekunene Iquka inani elikhulu lezi zilwanyana eziginya imijelo emikhulu yamanzi zize ziwanyanzele ukuba anqumle ngeendlela ezithile zokusikwa, ezivunyiweyo njengeenwele zobuso, ezihambisa amanzi kunye nokumisa ukutya okufunyenwe kwindawo yokudonsa.
Ngoko ke ukutya okubhaqwe kwiindiza kutyiwa, iminenga iyahluka kumalungu entsapho yayo kuba iqubha kwizikolo zekrill ivule imilomo, ifunze ikrill njengoko ihamba. ubukhulu obukhulu, ukuthathwa kwabo kulawulwa.
Ngaba bayancokola?
Abachongwa ngaphakathi izilwanyana zasemanzini ezisengoziniBanomdla kakhulu kwaye babonisa amandla amaninzi kunye nomdla xa bephakathi kwabantu. Kukho iimeko apho baye badinga ukuthwala iipontoon ezincinci kunye nee-kayakers ngasemva. Ukongezelela, banxibelelana kamnandi namahlengesi kunye neminenga enehumpback.
Indawo yokuhlala
Ngumnenga othatha indawo ebanzi ukusuka kuma-20 ukuya kuma-60° kuMzantsi wePasifiki, kuMzantsi weAtlantiki, nakuMazantsi oLwandlekazi lwaseIndiya. Ukusukela ngokungalindelekanga kule mizekelo kukubeka emngciphekweni wokususwa. Ukusukela ngenkulungwane ye-90, abemi bayo abakhethekileyo behle nge-XNUMX%.
Ngoku kukho malunga ne-8000 ephindwe kabini. Nangona bakwicala le-ikhweyitha kunye ne-axis esemazantsi, i iintlobo zeminenga zolusapho zizalela kumanzi ashushu ngexesha lasebusika. Ngoko zifumaneka kwiindawo ezahlukeneyo zehlabathi.
Ezi zidalwa zinegazi elifudumeleyo zinokakayi olude ukuya kuthi ga kwi-33% yobude bomzimba wonke, ekuqikelelwa ukuba xa umntu emdala buphakathi kwe-15 kunye ne-17 yeemitha. Zine-maxilla ethintelweyo kunye negobile, enika ezi zidalwa iprofayili eyahlukileyo kwezinye iintlobo.
Le milo ivumela ukusondela kwizinwele ezinde zobuso, eziziimitha ezi-5 ukuya kuma-25 ubude. Ngokungafaniyo neentlanzi, iminenga inemisila ejinga kwinqwelo-moya, nto leyo eyenza kube lula ukuba iphakamele phezulu, apho kufuneka inyuke ukuze iphefumle, nangona inokuhlala iyure ingaphantsi kwamanzi.
Caza
Njengoko isisidalwa esidada ngokuthe ngcembe size sityibilize xa sele sifile (ngokungafaniyo nezilwanyana ezinethambo lomqolo ezahlukeneyo), akukho nto inzima ukuyisukela, nto leyo esongeza kwindlela umzimba waso ovelisa ngayo oko kunokuthelekiswa nemiphanda yeoli engama-40 (iilitha ezingama-7200).
Isikhumbuzo seNdalo
NgoSeptemba 28, 1984, kwavunywa uMthetho No. Olu khetho luvela kwimfuno egqithisileyo yokuvumela ukhuseleko olufanelekileyo.
Ukuzala nokuncancisa amantshontsho azo kumanzi asezantsi. Ummandla waseRío Negro wawuvakalisa njengophawu oluphawulekayo njengendawo ngoMthetho onguNombolo 4066, owavunywa ngoAprili 6, 20067 kunye nePhondo laseSanta Cruz ngeNombolo 2643, wamkelwa ngoMatshi 13, 2003. Ithuba lokwenza indawo yokusabela. ukugcinwa kolu hlobo kuMzantsi weAtlantiki kuyagxininiswa.
Zinjani izithethe zokuthandana kwi-southern right whales?
Abasetyhini bafikelela kuphuhliso lwezesondo malunga nobudala be-9. Bakhawula inzala rhoqo emva kweminyaka emi-3 ukuya kwemi-4. Ixesha lokuvuselela liqala phakathi kukaJulayi ukuya ku-Agasti, kwaye imazi ijikelezwe ngabantu abanomdla. Uya kuqengqeleka emqolo ukuze agcine abucala akhe phezulu, ngaphandle kwamanzi, kwaye aphume kwikhampasi yamadoda ade abe sele elungile.
Curiosities
Skwaye ivelele phakathi kwayo iimpawu ze-southern right whale Abanayo lamina emqolo. Iigonads zolu sapho lweminenga zezona zikhulu emhlabeni, zinobunzima obungama-500 kg nganye.
Ngenxa yobuninzi bamaleko aluhlaza, iminenga esemazantsi ayinakungena kumanzi akweleenjiko njengoko ingakwazi ukusasaza ubushushu ngokukhawuleza ngokwaneleyo. Iminenga yaseSouthern right, ngamaxesha athile, ikhuphela intshinga yomsila emanzini ize iwuvumele umoya ubatyhale. Oku kuziphatha kwaziwa ngokuba "kukukhanya" kwaye kubonakala ngathi bakwenzela ukuzonwabisa.
