Kukhona izinhlanzi ezithola amagama azo ngendlela ezibukeka ngayo, njengakwindlela ye- inhlanzi zamatshe, futhi ngoba zifana nezinye izilwane, njenge I-Roosterfish. Lokhu kunjalo inhlanzi yengwenya. Njengoba igama layo liphakamisa, iyinhlanzi ebukeka icishe ifane naleyo yengwenya. Igama layo lesayensi ngu I-Atractosteus spatula. Idume, hhayi ngokubukeka kwayo kuphela, kodwa ngoba inamandla okungena nokuphuma emanzini. Iyakwazi ukufika emahoreni amabili esiphezulu ngaphandle kwamanzi ngaphandle kwenkinga. Kuyinhlanzi enelukuluku ngempela efanele ukwazi.
Kule ndatshana sizochaza konke mayelana nale nhlanzi yezingwenya, kusukela ezimfanelweni zayo eziyinhloko kuya ekudleni nasekukhiqizeni kwayo. Ufuna ukwazi okwengeziwe?
Izici eziyinhloko
Amandla ale nhlanzi ukungena nokuphuma emanzini kuyinto enhle njengoba ikunikeza ukwenza izinto eziningi ezihlukahlukene empilweni yakho. Izinhlanzi zikhawulelwa endaweni yasemanzini futhi, noma ngabe kukhona ukudla eduze kwabo, iqiniso lokuthi liphuma emanzini selivele liyakuvimbela ukuthi ungene kulo.
Ukubukeka kwengwenya kuphawuleka kakhulu ebusweni, ngoba inempumulo evulekileyo nomhlathi omfushane ongezansi. Inkulu impela ngosayizi, ifinyelela cishe kumamitha amathathu ubude futhi inesisindo esingamakhilogremu angama-3 Empeleni kukhona abantu abathi uma beyibona, bayiphambanise nezingwenya zangempela. Ezisikazi zivame ukuba zinkulu kuneyeduna, njengakwezinye izinhlobo eziningi. de peces.
Umbala wabo wesikhumba ubunsundu ngokumnyama engxenyeni engenhla futhi umbala ophuzi ngokwengeziwe engxenyeni engezansi. Woza, icishe ifane nengwenya yonke. Isizathu salokhu kufana asinayo incazelo. Izilwane ezihuquzelayo nezinhlanzi azinazo izici eziningi kakhulu ukuthi lezi zinhlobo ezimbili ziyefana. Inezimpiko ezinamabala ansundu kanti ezinye zinolayini ocacile ezinhlangothini zazo.
Ibanga nendawo yokuhlala
Izinhlanzi zengwenya zivame ukuhlala emachibini amakhulu, emifuleni nakwamanye amaxhaphozi. Bahlala emanzini amasha, yize bekwazi futhi ukukwenza emanzini anosawoti. Indawo yayo yokusatshalaliswa ihlanganisa izindawo ezinkulu zaseMelika. Ingatholakala ku- imilomo yemifula efana ne-Ohio neMississippi. Ibuye ihlale emachibini amakhulu njenge-Eire neMichigan (eyaziwa njengelinye lamachibi amakhulu emhlabeni) nasezindaweni ezinjenge-Alabama, Tennessee, Arkansas, Oklahoma, Georgia, Florida naseTexas.
Ikhetha amanzi angajulile ukubona kangcono isisulu sayo. Amanzi avulekile ayizintandokazi zakhe, njengoba enendawo eningi yokulungiselela ukuhlasela kwakhe. Njengenjwayelo, zihamba emanzini okujula kwawo kuphakathi kwamamitha ama-3 kuye kwayi-5 namanye amanzi asemanzini anamanzi amile.
Njengoba zikwazi ukuphuma emanzini amahora ambalwa, zingatholwa eduze nokushiswa yilanga lamanzi ngokungathi yizimfudu. Zibekwa eduze kwezihlahla, ibhulashi noma izingodo eziwela emanzini. Njengoba luhlobo lolwandle, sizohlala siluthola eduze kwamabhange lapho kungahle kube khona ukhula. Kuyaqabukela ukuwabona kumasayithi atholakele lapho angenakho ukuvikelwa nhlobo.
Ukudla kwezinhlanzi ezingwenya
Njengoba bekulindelekile, Yinhlanzi ukudla kwayo kudla inyama kuphela. Bathanda ukushwabadela ezinye izinhlanzi ezincane kunabo. Yize engadli kuphela ezinye izinhlanzi ezincane, kepha lapho indlala igadla, udla cishe noma yini. Bathanda ama-crustaceans afana nezimfanzi nezinkalankala futhi bangadla izinyoni zasemanzini, izimfudu, ngisho nezilwane ezincelisayo ezincane.
Noma indlala icindezela futhi kungekho zinsiza ezanele okuzungezile, ingadla isidumbu esisendleleni. Yize iyinhlanzi ebonakala ihamba kancane ngenxa yobukhulu bayo nesisindo sayo, iyakwazi ukuhlasela isisulu sayo ngejubane elikhulu nangokuqiniseka.
Ukuzala
Lolu hlobo lunokuziphatha okungajwayelekile kwezinye izinhlobo de peces. Ngokwesibonelo, banomkhuba woku ukuqoqa inani elikhulu labesilisa emanzini angajulile naseduze kohlaza. Yilapho abekwa khona, ngamunye ngamunye, ukuqhudelana ukubona ukuthi ngubani ophumelela owesifazane. Kumele sikhumbule ukuthi abesifazane bangavumela abesilisa abangaphezu koyedwa ukuba bavundise amaqanda. Ngakho-ke, isizathu sokuthi bancintisane sibi ngempela.
Lapho abesifazane bebeka amaqanda abo, banamathela emadwaleni noma ezimileni ukuze bakhule. Amaqanda aluhlaza okotshani futhi abomvu. Indlela yokunamathela kuma-substrates ukusinda. Uma kwenzeka zibonwa ezinye izidalwa futhi zibe sengozini yokugwinywa, ziye enye indlela yokuzivikela enkulu kakhulu: zinobuthi. Uma esinye isilwane sigwinya amaqanda, sizofakwa ubuthi.
Ukuzalela kwenzeka kancane noma kancane phakathi kwezinyanga zikaFebhuwari kuya kuJuni. Azinandawo ehleliwe, kepha usuku ngalunye lungahluka. Badinga nje ukhula namanzi angajulile.
Lezi zinhlanzi zinayo isikhathi sokuphila esiphakathi kweminyaka engama-25 nengama-50. Ngokuya ngezimo zemvelo ezikhona, zingahlala isikhathi eside noma zibe mfushane. Abesifazane ngokuvamile baphila isikhathi eside kunabesilisa.
Ngenxa yobukhulu nokuma kwazo, lezi zilwane azinazilwane ezidla ezinye endaweni yazo. Lapho zithosa uma kufanele qaphela i-alligator yaseMelika, ngoba bathanda inhlanzi yengwenya besebancane.
Ukuthuthukiswa komunwe
Lapho inhlanzi yengwenya ichanyuselwa eqandeni, izibungu ezincane ezinobude obungu-2,5 cm kuphela. Zintekenteke kakhulu futhi zizacile. Bangashukumisela ukubonga ngokunyakaza okufakwe intambo enomsila, yize le ntambo ingahlali isikhathi eside. Ayinankinga yokukhula, ngoba ikwenza ngejubane elikhulu. Uneminyaka emibili nje kuphela, singathola ama-specimens amadala ngokuphelele futhi athuthukisiwe.
Yize abesifazane bekwazi ukuba nosayizi wokugcina omkhulu, abesilisa bayakwazi ukukhula futhi bavuthwe ngaphambi kwesikhathi. Mhlawumbe lesi yisizathu esenza ukuthi babe nesikhathi esifushane sokuphila. Ngenkathi abesilisa bakhula ngama-48 cm ngonyaka, owesifazane ukhula kuphela ngezinga elingu-38 cm.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngezinhlanzi zengwenya.
