Sesiphi isilwanyana esinamazinyo ayi-100? Intshayelelo
Ngaba wakha wazibuza ukuba sisiphi isilwanyana esinamazinyo angama-100? Isenokumangalisa, kodwa eneneni kukho isilwanyana esinophawu olulolo hlobo. Isilwanyana esinamazinyo alikhulu, nesaziwa ngokuba yi-pacu fish, yintlanzi yasemanzini acwengileyo efumaneka kwi-Amazon nakweminye imilambo ekuMzantsi Merika. Uphawu lwayo olwahlukileyo lokuba namazinyo ali-100 yenze ukuba ibe sisihloko esithandwayo sengxoxo phakathi kwezazinzulu kunye noluntu ngokubanzi ngokufanayo.
Kweli nqaku, siza kuphonononga i-anatomy, indawo yokuhlala, ukutya, kunye nembali yendaleko yesilwanyana esinamazinyo alikhulu. Kwakhona siza kuxubusha indima yawo kwinkcubeko ethandwayo, kwimigudu yokulondoloza, noko kunokufundwa ngabantu kwesi sidalwa sibangel’ umdla.
Isidalwa esiNcedayo esinamazinyo ayi-100
Intlanzi ebizwa ngokuba yi<em>pacu fish, ekwaziwa ngokuba sisilwanyana esinamazinyo alikhulu, yintlanzi esemanzini acwengileyo enokukhula ibe ziimitha ezintathu ubude ize ibe nobunzima obungaphezu kweekhilogram ezingama-50. Ifumaneka ikakhulu kwi-Amazon basin nakweminye imilambo yaseMzantsi Melika, kodwa iye yaziswa nakwezinye iindawo zehlabathi ngeenjongo zokufuya emanzini. Intlanzi ye-pacu isihlobo esisondeleyo se-piranha kwaye inomzimba ofanayo, kodwa amazinyo ahlukeneyo.
Nangona isisihloko esithandwayo sengxoxo, intlanzi ye-pacu sisidalwa esingaqhelekanga ekunzima ukusifunda endle. Indawo yayo yokuhlala ekhethwayo ngamadama anzulu anamanzi ahamba kancinci, okwenza kube nzima ukuqaphela kunye nokulandela umkhondo. Nangona kunjalo, izazinzulu ziye zakwazi ukuqokelela ulwazi malunga ne-anatomy yesilwanyana esinamazinyo alikhulu kunye nokuziphatha ngokusebenzisa iinkqubo zokuzala kunye nezifundo zokuqhawula.
IAnatomy yeSilwanyana esinamazinyo alikhulu
Njengoko igama layo libonisa, intlanzi ye<em>pacu inamazinyo ali-100 alungelelaniswe ngokwepateni efana nomntu. Kunokuba ibe namazinyo abukhali njengepiranha, i<em>pacu fish inamazinyo asicaba, asisikwere asetyenziselwa ukutyumza ixhoba elinoqweqwe oluqinileyo njengamandongomane nembewu. Amazinyo esi silwanyana sinamazinyo alikhulu nawo alungele ukucola nokutyumza i-exoskeletons ye-crustaceans kunye ne-snails, eyenza inxalenye ebalulekileyo yokutya kwayo.
Intlanzi ye-pacu inomzimba olungelelanisiweyo ovumela ukuba uhambe ngokukhawuleza emanzini. Ikwanemihlathi enamandla ekwaziyo ukusebenzisa amandla afikelela kwiikhilogram ezingama-50, nto leyo eyenza ibe ngomnye wemihlathi eyomeleleyo kuyo nayiphi na intlanzi yasemanzini. Izihlunu zemihlathi yesilwanyana esinamazinyo alikhulu zomelele kangangokuba zaziwa ngokwaphula intambo namagwegwe.
Isilwanyana esinamazinyo alikhulu siwasebenzisa njani amazinyo aso?
Intlanzi ekuthiwa yi<em>pacu isebenzisa amazinyo ayo ukutyumza ixhoba elinoqweqwe oluqinileyo, kuquka amandongomane, imbewu neziqhamo. Ikwatya ngeecrustaceans, iinkumba, kunye neentlanzi ezincinci. Isilwanyana esinamazinyo alikhulu, amazinyo angama-square alungelelaniswe ukucola kunye nokutyumza i-exoskeletons eqinile yexhoba laso, elivumela ukuba lifikelele kwi-interior ecebileyo yezondlo.
Amazinyo entlanzi ekuthiwa yi<em>pacu nawo ayasetyenziswa kunxibelelwano nakwindlela yokuziphatha ekuhlaleni. Ngexesha lokuzala, iinkunzi zisebenzisa amazinyo ukutsala iimazi ngokucofa ingxolo. Bakwasebenzisa amazinyo abo ukuseka ukongamela kunye nommandla phakathi kwamanye amadoda.
Ukutya kweSilwanyana esinamazinyo alikhulu kunye nendawo yokuhlala
Intlanzi ye-pacu luhlobo lwe-omnivorous olutya iintlobo ezahlukeneyo zokutya. Ukutya kwayo kuquka amandongomane, imbewu, iziqhamo, ii<em>crustaceans, iinkumba neentlanzi ezincinane. Isilwanyana esinamazinyo alikhulu sikhetha ixhoba elinamaqokobhe aqinileyo ngenxa yamazinyo aso awodwa alungele ukutyumza nokusila amathambo eexoskeleton aqinileyo.
Intlanzi ye-pacu ifumaneka ikakhulu kumachibi anzulu anamanzi ahamba kancinci, apho inokufumana indawo yokuhlala kunye nokutya. Ikhetha iindawo ezinohlaza oluxineneyo kunye nezigodo eziphantsi kwamanzi okanye amasebe, abonelela ngokusithela kunye neendawo zokufihla.
Imbali yeNdalo yeSilwanyana esinamazinyo alikhulu
Intlanzi ye-pacu inembali ende yendaleko eyaqala kwizigidi zeminyaka. Kukholelwa ukuba yavela e-Afrika kwaye yafudukela eMzantsi Melika ngexesha leMiocene. Amazinyo akhethekileyo esi silwanyana esinamazinyo alikhulu kucingelwa ukuba aye avela ngenxa yokutya kwaso okutyiwa zii-omnivorous kunye nemfuneko yokutyumza ixhoba eliqinileyo.
Intlanzi ye-pacu inxulumene ngokusondeleyo ne-piranha kwaye yeyosapho lwe-Characidae. Noko ke, ngokungafaniyo ne<em>piranha, isilwanyana esinamazinyo alikhulu asilozilwanyana ezizingelayo kwaye asikho sisongelo ebantwini.
Isilwanyana esinamazinyo alikhulu kwinkcubeko edumileyo
Intlanzi ye-pacu ifumene udumo kwinkcubeko eyaziwayo ngenxa yesethi yayo yamazinyo kunye nokufana nepiranha. Ibonakaliswe kwimiboniso bhanyabhanya emininzi yeTV, kubandakanywa iDiscovery Channel ye "River Monsters" kunye nefilimu eyoyikisayo ye-comedy "Piranha 3D."
Isilwanyana esinamazinyo alikhulu sikwangumxholo wamabali aliqela asezidolophini, kuquka nentsomi yokuba sihlasela size sibulale abantu. Noko ke, abukho ubungqina benzululwazi obuxhasa la mabango, yaye intlanzi ye<em>pacu ayijongwa njengesisongelo ebantwini.
Iinzame zoLondolozo lweSilwanyana esinamazinyo alikhulu
Intlanzi ye-pacu okwangoku ayidweliswanga njengeentlobo ezisengozini yokuphela. Nangona kunjalo, inani labo liye lehla kwezinye iindawo ngenxa yokuloba ngokugqithisileyo kunye nokutshatyalaliswa kwendawo yokuhlala. Iinzame zolondolozo ziyaqhubeka ukukhusela indawo yokuhlala yezilwanyana ezinamazinyo alikhulu kunye nokuqinisekisa iindlela zokuloba ezizinzileyo.
Ukongezelela, amanye amazwe aye amisela imithetho ephathelele ukungeniswa nokurhweba kweentlanzi ze<em>pacu ukuze kuthintelwe ukwanda kweentlobo zezilwanyana eziyingozi.
Ukufana kunye neeyantlukwano kunye nezinye izilwanyana ezinamazinyo
I-pacu fish enamazinyo akhethekileyo ali-100 iyenza yahluke kwezinye izilwanyana ezinamazinyo, kuquka ookrebe, iingwenya neminenga. Ngelixa ezi zilwanyana zinamazinyo abukhali alungele ukuzingela nokubulala ixhoba, amazinyo esilwanyana esinamazinyo alikhulu alungele ukutyumza ixhoba elinamaqokobhe aqinileyo.
Noko ke, intlanzi ebizwa ngokuba yi<em>pacu inento efanayo nesalamane sayo esisondeleyo, i<em>piranha. Zombini ezi ntlobo zinomzimba ofanayo kwaye zifumaneka kwindawo enye. Noko ke, amazinyo abukhali e<em>piranha nokuziphatha okuzingelayo kuyenza ibe yingozi ngakumbi kunesilwanyana esinamazinyo alikhulu.
Ngaba Abantu Banokufunda Nto Nto Kwisilwanyana Esinamazinyo Alikhulu?
Amazinyo akhethekileyo entlanzi ye-pacu kunye nokutya okudliwayo kusenokubafundisa izinto ezibalulekileyo abantu. Ikhono layo lokutya ukutya okuqinileyo, okuqinileyo kunokubonelela ngengqiqo ekuphuhliseni itekhnoloji esebenzayo yokulungisa ukutya. Ukongezelela, izihlunu zemihlathi yesilwanyana esinamazinyo alikhulu kunye namandla okuluma kunokubangela ukuba kwenziwe izinto ezomeleleyo nezihlala ixesha elide.
Uphando Lwexesha elizayo ngeSilwanyana esinamazinyo alikhulu
Nangona ingumxholo odumileyo wengxoxo, intlanzi ye-pacu ihlala iyintlobo engafundiswanga. Uphando lwexesha elizayo lunokujolisa kwindlela esiziphethe ngayo esi silwanyana sinamazinyo alikhulu, i-ecology, kunye nokwakheka kwemfuza. Ukongeza, kukho imfuneko yophando olongezelelekileyo malunga nefuthe lemisebenzi yabantu kuluntu lwentlanzi ye-pacu kunye nendawo yokuhlala.
Iingcinga zokuvala kwiSilwanyana esinamazinyo alikhulu
Intlanzi ebizwa ngokuba yi<em>pacu fish, ekwaziwa ngokuba sisilwanyana esinamazinyo alikhulu, luhlobo olunomtsalane olunamazinyo akhethekileyo ali-100. Ukutya kwayo kwe-omnivorous kunye nokukwazi ukutya ixhoba elilukhuni likwenza ukuba libe yinto ebalulekileyo yophando kwinzululwazi kunye nesihloko esithandwayo sengxoxo phakathi koluntu jikelele. Ngoxa isilwanyana esinamazinyo alikhulu singagqalwa njengesisongelo ebantwini, kufuneka iinzame zokusilondoloza ukuze kukhuselwe indawo esihlala kuyo nokuqinisekisa ukuloba ngokuqhubekayo.
