Esinye sezilwane ezibaluleke kakhulu emanzini olwandle ushaka. Kunezinhlobo eziningi zikashaka emhlabeni jikelele. Kukhona labo ababambelele kakhudlwana futhi abayingozi kangako futhi kukhona labo abayingozi kubantu nakunoma yiluphi uhlobo lwasolwandle olusondela eduze kwalo. Kulokhu, sizokhuluma ngakho ushaka wesando. Indima yayo njengesilwane esidlayo ibalulekile ngoba ibamba iqhaza elibalulekile ekulawuleni abantu abahlukahlukene ezindaweni eziphila olwandle.
Kulesi sihloko, uzofunda konke mayelana ne-hammerhead shark, kusuka kuzimpawu zayo eziyinhloko kuye ukuthi yondla kanjani nokuthi izala kanjani.
Izici eziyinhloko
Lo shaka waziwa ngamanye amagama ajwayelekile njengama-giant anezimpondo. Igama layo lesayensi yiSphyrna mokarran. Kungumndeni wakwaSphyrnidae. Phakathi kwezici ezigqame kakhulu zalolu shaka sithola ikhanda lalo elime ngo-T. Lesi yisona sizathu esenza le nhlanzi yaziwe njenge-hammerhead shark. Uma sihlola wonke umzimba walo shaka, sizobona ukuthi ubunjwe njengesando. Singasho ukuthi umzimba wonke yisibambo esithatha ngaso. Ikhanda elime ngo-T ligcina liyingxenye yensimbi esishayela ngayo izinzipho.
Leli khanda elimise okwe-T alikuniki nje kuphela obekuyisici esibukwayo esihlukile. Ngenxa yalesi simo esehlukile, Lo shaka uyakwazi ukubona ama-degree angama-360. Njengoba ungacabanga, lolu hlobo lwesici luletha ukuthuthuka okukhulu kumakhono alo wezinzwa nethalente lawo lokuzingela nokwenza njengesihlaseli.
Yisilwane esikhulu ngokwanele esinobukhulu obumaphakathi obungamamitha ayi-3,5 kuye kwangama-4. Kwezinye izindawo, abantu abafinyelela kumamitha ayisithupha ubude batholakele. Lokhu kwehluka kakhulu ekwakhiweni komzimba, i-ecosystem lapho ikhula khona, inani lokudla elitholakalayo, amandla alo ezimoto, njll.
Inhloko emise okwe-T ikusiza ukuthi uthuthukise umbono wakho futhi, ngenxa yokuzivumelanisa kwayo nemvelo yasolwandle, nayo ingaguqula umzimba wakho ngokushesha. Isilwane esinobukhulu obunjalo, ukuguqula ukuqondiswa kanye nokuqondiswa lapho siphishekela isisulu saso kuyinkimbinkimbi ngokwengeziwe. Ngokunikezwe lokhu, ikhanda elimise okwe-T lisebenza ekulindeleni ukunyakaza kwesisulu futhi ligcine lishintsha ukuqondisa kwalo nomqondo walo ngejubane elikhulu.
Ukuhluka kwabanye oshaka
Bayizilwane ezihlaba umxhwele ngempela. Kuthiwa ukuthi Ushaka omhlophe Iyesatshwa kakhulu futhi yaziwa kubo bonke. Kodwa-ke, i-hammerhead shark inezici ezithile ezenza ikhetheke. Banokuthuthuka kwezinzwa eziyisi-7 kakhulu. Abagcini nje ngokuba nezinzwa esizaziyo kumuntu, kodwa banezinye ezimbili. Elinye lisetshenziselwa ukuhlukanisa amaza emvamisa kanti elinye ukuthola inkambu kagesi ekhishwa ezinye izinhlanzi. Le mizwa emibili emisha ilusizo kakhulu kubo lapho ifuna futhi ibamba inyamazane. Akusizi ngalutho ukuthi zicashe ngemuva kwamatshe athile, ushaka wesando uzokwazi ukuwathola ngalezi zinzwa ezimbili esezithuthuke kakhulu.
Umlomo walesi silwane utholakala engxenyeni engezansi yekhanda. Umlomo wayo awumkhulu ngokwanele ukuthi ungabamba inyamazane enkulu, kodwa yebo inamazinyo abukhali ngokumangalisayo ukudabula kangcono. Ngenxa yamazinyo abukhali inesilinganiso sokubamba esinamathuba aphezulu okuphumelela.
Ngokuqondene nombala, ungwevu okhanyayo ngokuluhlaza futhi lokhu kuvumela ukuthi kudideke ngaphansi kolwandle ukuze kungatholakali. Ingxenye ye-ventral ilula ngombala kunezinye.
Ukuziphatha nendawo yokuhlala
Emini kuvame ukubonakala kwakhiwa amaqembu athile ezinhlobonhlobo ezimbalwa. Lapho sebeseqenjini elikhulu abavamisile ukuzingela kakhulu ngoba abakwazi ukuzifihla noma ukucasha. Ukuba yizibonelo eziningi futhi ezinosayizi omkhulu kangako, kunzima ukungaziwa phakathi kwayo yonke inyamazane.
Ebusuku kungenye indaba. Yilapho bathambekele ekubeni nezikhathi zokuzingela ezihamba phambili., kwazise bahamba bodwa. Ezinye izibonelo zinokuziphatha okuthe xaxa nokungabi nabungozi kunezinye. Imvamisa, kuya ngosayizi wazo, zinolaka oluncane noma oluncane. Oshaka abakhulu kunabo bonke be-hammerhead banokuhlaselwa okuyingozi kakhulu nobudlova obukhulu. Isikhathi sabo sokuphila sivame ukuba yiminyaka engama-30 bekhululekile. Le nkathi yokulinda impilo ingaphansi kwezingozi ezingaba khona uma zithathwa ngabantu noma ziphathwa ekuthunjweni.
Ngokuqondene nendawo ehlala kuyo, yize isengozini yokuqothulwa ngokwedatha ye-IUCN, singakuthola cishe kuwo wonke umhlaba. Inala yayo inkulu kakhulu ezindaweni ezinamanzi ashisayo futhi aphakathi nendawo. Abakhethi amakhaza, zama ukuwugwema. Indawo yomsebenzi omkhulu kunayo yiyona eseduze nemingcele. Ukujula kwamanzi ababhukuda kuwo kungaphansi kwamamitha angama-280.
Ngokuvamile babhukuda emanzini azolile. Ngokwendawo, sithola inani elikhulu kunawo wonke le-hammerhead shark e-Indian Ocean, eGalapagos Islands naseCosta Rica.
Ukondla nokuzala kabusha
Njengoshaka abaningi, kuyisilwane esidla inyama. Lokhu kudla kwenziwa kakhulu izinhlanzi, ama-squid, ama-eel, amahlengethwa, izinkalankala, iminenke nokudla okuthandwa yibo okuyimisebe.
Udumo lokuba yisidlakela esikhulu selutholakele ngenxa yekhono lalo lokubamba izilwane kalula. Kodwa-ke, abadli abantu futhi akufanele ucabange ukuthi usengozini uma uhlangabezana nenye yazo.
Ushaka we-hammerhead uphephela isisulu sakhe futhi isebenzisa ikhanda layo ukushaya kanye nokwenza buthaka isisulu sayo.
Njengoba kuyizilwane ezihlala zodwa, ukuzala akwenzeki kaningi. Kuyinto yezinhlobo ze-viviparous. Izala njalo eminyakeni emibili uma sebefinyelele ekukhiqizeni ngokocansi. Inani lentsha livame ukuhluka kuye ngobukhulu besifazane. Isikhathi sokukhulelwa sihlala cishe izinyanga eziyi-10.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi nge-hammerhead shark nezimpawu zayo eziyinhloko.
