I-southern right whale iyisidalwa esimangalisayo sasolwandle, inezici ezikhethekile ezikhangayo kakhulu, ezinobukhulu bomzimba obukhulu kakhulu, obukhulu kakhulu kunabo bonke abantu abavamile. Thola, futhi ufunde okwengeziwe ngalesi silwane.
Descripción
Ubude bayo busuka ku-512 kuya ku-590 amayintshi owesilisa futhi azungeze ama-intshi angu-630 kwabesifazane. Zilethwa emhlabeni ngamamitha ama-3 ukuya ku-5, ukusuka ekhaleni ukuya emsileni. Isisindo sawo sihluka phakathi kwamathani angu-40 uma sebenempilo ethuthukisiwe.
Ama-calluses angabonakala, okuyizindawo eziphakanyisiwe zesikhumba ezingaphezu kuka-5 cm ubukhulu, ezinokuqina kwe-cornea, etholakala ezingxenyeni ezihlukahlukene zekhanda. Ukusabalala, ubukhulu, nesimo sama-calluses kuyashintshashintsha kuqala ngengxenye eyodwa yomkhomo bese kuthi elandelayo, nokho, angashintshi ngokukhula.
Ama-calluses akhiwa esigabeni se-fetus futhi anomthunzi omnyama, lawa ma-calluses ahlanganisa inqwaba yama-amphipod amancane abizwa ngokuthi ama-cymacids (izintwala zomkhomo) futhi ngezikhathi ezithile axutshwa nama-cirripedes okwenza ama-calluses abonakale amhlophe, aphuzi, awolintshi noma apinki okhanyayo.
Ingabe banazo izilwane ezidla ezinye zemvelo?
I-Southern Right Whales iyaziwa ngokudliwa yi-Patagonian Gulls. Ama-Gulls adala izilonda eziningi esikhumbeni semikhomo, naphezu kwalokhu, imikhomo ichitha amandla amaningi isuka kuma-gulls, okusho ukuthi ichitha isikhathi esincane inakekela amathole. Ezintsha nazo azinamandla okumelana nemikhomo ebulalayo noshaka abakhulu abamhlophe.
Ama-southern right whale aziphilisa kanjani?
La ukondla imikhomo engakwesokudla Iqukethe inani elikhulu lalezi zilwane ezigwinya imisele emikhulu yamanzi bese iziphoqa ukuba ziwele ngokusebenzisa imiphetho ethile, egunyazwe njengoboya bobuso, obuhambisa amanzi futhi bumise ukudla okutholakala lapho kuhudulwa.
Ngakho-ke ukudla okubanjwa obishini kudliwa noma kunjalo, imikhomo iyahluka kumalungu omndeni wayo ngokuthi ibhukuda phakathi kwezikole ze-krill ivule imilomo, iqhubekisela phambili ama-krill njengoba ihamba. ubukhulu obukhulu, ukudla kwabo kuyalawulwa.
Ingabe banobudlelwane?
Abahlonzwa ngaphakathi izilwane zasemanzini ezisengoziniBanelukuluku lokwazi futhi bakhombisa amandla amaningi nomdlandla lapho bephakathi kwabantu. Kunezimo lapho beye badinga ukuthwala ama-pontoon amancane nama-kayakers ngemuva. Ngaphezu kwalokho, baxhumana kahle namahlengethwa nemikhomo yama-humpback.
Habitat
Iwumkhomo othatha indawo ebanzi esukela ku-20° kuya ku-60° eSouth Pacific, eSouth Atlantic, naseSouth Indian Oceans. Ukuphishekela okungalindelekile kwalezi zibonelo kukubeka engcupheni yokususwa. Kusukela ngekhulu le-90, inani labantu bakhona eliyingqayizivele lehle ngamaphesenti angama-XNUMX%.
Njengamanje kunezimpinda ezingaba ngu-8000. Nakuba zisohlangothini lwenkabazwe kanye ne-axis eseningizimu, i izinhlobo zemikhomo zalo mndeni zizalela emanzini afudumele ebusika. Ngakho zitholakala ezindaweni ezihlukahlukene zomhlaba.
Lezi zilwane ezinegazi elifudumele zinogebhezi olude olufinyelela ku-33% wobude bomzimba wazo, okuthi lapho sezikhulile kulinganiselwa ukuthi buba phakathi kwamamitha ayi-15 no-17. Zine-maxilla ekhawulelwe futhi egobile, enikeza lezi zidalwa iphrofayili ehlukile kwezinye izinhlobo.
Lesi simo sivumela ukusondelana nezinwele ezinde zobuso, ezingamamitha angu-5 kuya kwangu-25 ubude. Ngokungafani nezinhlanzi, imikhomo inemisila elenga endizeni, okwenza kube lula ngayo ukukhuphukela phezulu, lapho kufanele ikhuphuke ukuze ihogele, nakuba ingahlala ihora lonke icwile emanzini.
Caza
Njengoba iyisidalwa esibhukudayo kancane kancane futhi sishibilike lapho sesifile (ngokungafani nezilwane ezihlukahlukene ezinomgogodla), akulula ukusijaha, okwenezela endleleni umzimba waso okhiqiza ngayo okungase kuqhathaniswe nemiphongolo kawoyela engama-40 (amalitha angu-7200).
Isikhumbuzo Semvelo
Ngo-September 28, 1984, kwavunywa uMthetho No. 23094, umemezela isici esiyingqopha-mlando somkhomo ngamunye obonwa emanzini ase-Argentina. Lokhu kukhetha kuvela esidingweni esidlulele sokuvumela ukuvikeleka okufanele.
Ukuzalanisa nokuncelisa amazinyane azo emanzini aseningizimu. Indawo yase-Río Negro iphinde yamemezela ukuthi iyindawo eyingqophamlando njengendawo ngoMthetho No. 4066, owavunywa ngomhla ka-April 6, 20067 kanye neSifundazwe saseSanta Cruz ngoNombolo 2643, wagunyazwa ngoMashi 13, 2003. Amathuba okwenza indawo yokukhosela. ukulondolozwa kwalolu hlobo eNingizimu ye-Atlantic kuyagcizelelwa.
Anjani amasiko okuqomisana ama-southern right whales?
Abesifazane bafinyelela ekukhuleni kocansi cishe eminyakeni engu-9 ubudala. Bakhulelwa inzalo njalo eminyakeni emi-3 kuya kwemi-4. Isikhathi sokuvuselela siqala phakathi kukaJulayi kuya ku-August, futhi insikazi izungezwe abantu abangase bathande. Uzogingqika emhlane wakhe ukuze agcine izimfihlo zakhe ziphezulu, ngaphandle kwamanzi, futhi ngaphandle kwekhampasi yamadoda aze alungele.
Curiosities
Sfuthi ivelele phakathi kwayo izici ze-southern right whale Abanayo i-lamina emhlane. Ama-gonads alo mndeni wemikhomo yiwona amakhulu kunawo wonke emhlabeni, anesisindo esingama-500 kg ngalinye.
Ngenxa yogqinsi lwawo lwama-blubber, ama-southern right whales awakwazi ukungena emanzini ashisayo njengoba engakwazi ukuhlakaza ukushisa ngokushesha ngokwanele. Ama-Southern right whales, ngezikhathi ezithile, akhiphe umsila wawo emanzini futhi adedele umoya ohelezayo. Lokhu kuziphatha kwaziwa ngokuthi "ukukhanyisa" futhi kubonakala sengathi bakwenzela ukuzijabulisa.
