Inhlanzi yesawudo iphila ngokuvumelana negama layo. Umzimba wayo omude nomlomo omise okwesaha kwenza le nhlanzi yesatshwe kakhulu. Igama lesayensi ngu I-Pristis pristis futhi ingeka-oda lama-Pristiformes. Kulesi sihloko sizohlaziya le nhlanzi enhle ngokujulile ukuze ufunde kabanzi ngayo.
Ngabe ufuna ukufunda zonke izici nendlela yokuphila kwe-sawfish?
Izici eziyinhloko
Umndeni we-sawfish unemikhakha emibili nezinhlobo eziyisikhombisa. Zihlobene kakhulu noma kancane ngemivimbo futhi zifaka amathambo agcwele uqwanga. Isichasiso esikhulu kunazo zonke nalokho okwaziwayo ukuthi kungenxa yokuthi isifonyo sifana nesaha. Isifonyo sigoqwe ngenqwaba yama-pores asivumela ukuthi sikwazi ukuthola noma yikuphi ukunyakaza ukuze sikwazi ukuzingela. Lokhu kukunika inzuzo enkulu enkundleni.
Amandla akhe wezinzwa makhulu kangangokuba iyakwazi ukubona ukushaya kwenhliziyo kwanoma yisiphi isilwane. Iningi lemisebenzi yenziwa ngenxa yesifonyo kumodi yesarha. Isebenzela ukuhlasela nokuvikela. Kuyithuluzi elilinganiselwe kahle elingabamba isisulu sokushwabadela ngokushesha. Iyisebenzisela ukuzivikela ezilwanyaneni ezifana namahlengethwa noshaka. Ayinawo amazinyo, kodwa izikali zamazinyo.
Isifonyo sakhiwa ngamazinyo angama-23 lokho kuhamba phambili. Inkulu kangangoba imele ngaphezu kwengxenye yesine yomzimba wayo. Zingahamba ngezindlela ezahlukahlukene ukuhlasela inyamazane yazo eziyilimaze ngesaha. Imbozwe ngokuphelele kuma-pores wezinzwa akusiza ukuthi ubone konke okuzungezile.
I-Sawfish ingazingela ngezindlela ezimbili. Okokuqala ukusebenzisa isifonyo sayo njengebhulashi. Ngale ndlela ikwazi ukuheha isihlabathi kusuka ezindaweni lapho kucashe khona izilwane ezinjengezinkalankala, izinkalankala nezinhlanzi. Ingase futhi icindezele isisulu sayo njengama-mullet aqabulayo, nezinye izinhlobo. Kodwa-ke, isisulu esilula soshaka lapho sebekhulile.
Njengoba zikhula ziyakwazi ukuzivikela ezilwaneni eziyingozi ezisolwandle.
Ukuziphatha
I-sawfish yisilwane sasebusuku, bengenzi lutho futhi bachitha usuku lwabo bephumula ngokuthula ukuze basebenze ebusuku nokuzingela. Ngaphandle kokuthi ukubukeka kwazo kungabonakala kuyingozi futhi kubeka ukwesaba, bayizinhlanzi ezingenzi lutho futhi abakwazi ukuhlasela abantu. Kodwa-ke, njengezinhlobo eziningi, uma zisongelwa noma zihlaselwa, ngeke zinqikaze ukuzivikela.
Kuyisilwane esihlala kahle esichitha isikhathi esiningi sokuphumula ezindaweni ezinokuthula. Imvamisa ibekwa duzane nenhlabathi enesihlabathi lapho ingathola khona inyamazane ethile ngaphansi kwesihlabathi. Njengezinye izinhlobo zazo, ama-batoid elasmobranchs angaphefumula esebenzisa izigaxa ezinkulu anazo emehlweni abo.
Indawo nendawo okusatshalaliswa kuyo
Singathola i-sawfish ezindaweni ezishisayo nakwezindawo ezishisayo. Ayatholakala ezindaweni zase-Australia, e-Afrika, e-Ecuador, ePortugal nakwezinye izindawo zaseCaribbean. Izivakashi ziyayibona njengoba zihlala emanzini angajulile.
Iyakwazi ukuhlala emanzini ahlanzekile futhi anosawoti. Zibekwa kakhulu emilonyeni yemifula lapho umehluko wamanzi ahlanzekile nosawoti ungagcizeleli imetabolism. Ngenxa yesimo salezi zinhlanzi ziyakwazi ukusebenza ezindaweni ezihlukene zasemanzini. Bangakwazi ukuhlala ezindaweni ezibanikeza ukudla nokuthula ukuze baphumule emini.
Zitholakala kwezinye amachweba kanye namatheku lapho ahlala khona akunazinkinga. Isungulwe eduze neGulf of Mexico ngaseningizimu nge-Atlantic nePacific. Kwezinye izindawo lisetshenziswa njengomuthi ohlukile kwezinye izifo zokuphefumula.
Njengoba isikhathi sakhe esiningi esichithwa ezindaweni ezinodaka nezinesihlabathi, usisebenzisa ngokunenzuzo ukuzimba nokuzijabulisa. Ngalokhu usebenzisa isaha lakhe futhi ezikhathini eziningi ugcina ethola inyamazane azondla ngayo. Kuyathakazelisa ukuthi angabonakala enza lesi senzo ukuze nje aziphazamise lapho kuhlwa.
Isisulu esilula kunazo zonke inhlanzi yasendaweni eshisayo, ngoba ayinaso isimiso esihle sokuzivikela. Ukusatshalaliswa kwale nhlanzi kugxile ezindaweni lapho ngaphambili yayihlala khona ngobuningi bayo. Zitholakala emanzini ase-United States, ikakhulukazi kulawo aseNew York, eFlorida naseTexas.
Ukudla kwe-Sawfish
Ukudla kwabo kususelwa kuma-invertebrate amakhulu nama-mollusks amakhulu. Ngaphezu kwalokho, ibuye idle ezinye izinto eziphilayo ezitholakala ekujuleni kwamanzi. Noma behlala endaweni efanayo futhi inhlanzi inesibindi sokuyidla, akukaze kubonakale ukuthi idle inhlanzi zamatshe.
Uma ufuna ukubamba le nhlanzi, ayinayo inkinga. Kodwa-ke, Ayidliwa njengezinye izinhlobo de peces. Okwamanje kukhona ukuhweba ngesahafish kanye nokuthunyelwa kwamanye amazwe okuchumayo.
Ngokuvamile, ukusetshenziswa kwale nhlanzi kwenziwa usawoti futhi cishe njalo kubanjwa ngokudoba izimfanzi. Inani elikhulu alitholakali ngoba akuyona into eyinhloko yokudoba. Iqukethe inani elikhulu le-mercury, ngakho-ke akunconywa ukuthi kudliwe ngobukhulu obukhulu. Lesi yisizathu sokuthi kungani ingazange idume kakhulu ku-gastronomy yamazwe.
Ukuzala
Akukho okuningi okwaziwayo ngokukhiqizwa kabusha kwe-sawfish. Okwaziwayo ukuthi ziyi-ovoviviparous, ngakho-ke ukuzala kwazo kweqanda kukhula ngaphakathi kowesifazane kuze kufike isikhathi sokuchanyuselwa. Lapho befika eminyakeni ecishe ibe yi-10 yeminyaka kulapho bafika ekuvuthweni okugcwele. Uma bengabanjwa izidlakela zabo noma abantu, imvamisa iba nesikhathi sokuphila seminyaka engama-30.
Ukuze bafinyelele ekuvuthweni ngokocansi kufanele babe ngamamitha amane ubude neminyaka eyi-10 ubudala. Ukukhiqizwa kwayo akukuningi kakhulu, okwenza kube sengozini enkulu ekudobeni ngokweqile. Izinga lokukhiqizwa kwale sawfish liphansi impela futhi lingaqhathaniswa ne- isfishfish noma i-marlin enesistimu yokuzala ehamba kancane
Ukuzala kwenzeka ngaphakathi izinyanga zika-Ephreli kuze kube sekupheleni kukaJuni.
Ngalolu lwazi ungafunda kabanzi nge-sawfish. Uyithandile? Sazise kumazwana 🙂
