Piranha wamba ndi nsomba yolusa yochokera ku banja lalikulu la characin-piranhas. N’zovuta kupeza munthu amene sakudziwa za kukhalapo kwa nsomba imeneyi. Kuyambira tili ana, kuchokera kuzinthu zosiyanasiyana, timauzidwa za ludzu la piranha. Mbiri ya mtundu uwu ndi woti sizidziwika nthawi zonse pamene, komabe, zoona ndi kuti zopeka. Ndikoyenera kudziwa kuti si nsomba zonse za m'banjali zomwe ziyenera kuonedwa kuti ndizoopsa. Mwachitsanzo, metinnis (Metynnis) kapena nsomba genera Colossoma (Colossoma) ndi Mileus (Myleus), maziko a zakudya amene zosiyanasiyana zomera zomera. Ponena za adani, amaimiridwanso ndi magulu angapo, kuphatikizapo mitundu yotchuka kwambiri, piranha wamba ( Pygocentrus nattereri ). Ichi ndi nsomba yaying'ono, yomwe kutalika kwake kumakhala 15-20 cm. Koma kukula kwakukulu kumatha kufika 50 cm ndikulemera mpaka 4 kg. Nthawi zambiri, pakati pa mitundu ina ya ma piranha, pali anthu opitilira 1 m kutalika. Thupi la nsomba lili ndi mawonekedwe ozungulira, ophwanyidwa mwamphamvu kuchokera kumbali. Kwa piranha wamba, mtundu wa kumtunda kwake ndi azitona wakuda, ndipo mbali zake ndi zasiliva. Thupi lonse lili ndi mamba ang'onoang'ono. Ali aang'ono, nsomba zimakhala zamitundu yowala, zikakula, zimakhala zakuda. Kawirikawiri, mbali imeneyi ndi khalidwe la mitundu yonse yaikulu. Pali zipsepse ziwiri kumbuyo, chakumbuyo ndi chaching'ono ndikusunthira kumchira. Nsomba zonse za m'banjamo zimakhala ndi milomo yamnofu, yomwe nthawi zambiri imawonongeka panthawi yosaka ndi kumenyana ndi internecine. Zibwano zili ndi mano ambiri ooneka ngati mphero. Nsagwada zapansi zimasunthidwa kutsogolo, zomwe zimapangitsa kuti mawonekedwewo akhale ovuta kwambiri. Kutalika kwa mano akuluakulu a nsagwada zapansi kumatha kufika 2 cm. Mphamvu ya kukanikiza nsagwada ndi yofanana ndi 320 Newtons. Anthu a Piranha ndi ochuluka ndipo amakhala m'madera osiyanasiyana a mtsinjewo. Amapanga magulu akuluakulu. Iwo ndi adani achangu, akudalira kufulumira kwa kuukira ndi kudabwa. Pagulu, amaukira ozunzidwa amtundu uliwonse. Pofufuza ozunzidwa, amadalira kwambiri kununkhira, masomphenya ndi mzere wotsatira. M'gulu la nsomba zina, odwala ndi ovulala amadziŵika mwamsanga, kuwonjezera apo, anthu omwe agonjetsedwa ndi mantha amadziwika nthawi yomweyo, zomwe zimakhalanso chizindikiro choukira. Ndizofunikira kudziwa kuti ma piranhas amatha kupanga symbiosis ndi mitundu ina ya nsomba, yomwe imachotsa tizilombo toyambitsa matenda, ndipo samasaka. Piranhas samaukira achibale awo ovulala. Kuwonongeka kwa thupi la ma piranha kumachira msanga. Palibe milandu yeniyeni ya anthu ophedwa yomwe imadziwika. Mitundu ina ya piranha imakonda kudya mamba a nsomba zina kapena zipsepse zamitundu yayikulu. Mitundu yambiri yodya udzu imatha, komabe, imadya ana a nsomba zina. Ena amachita chidwi ndi zipatso za zomera zapafupi ndi madzi. Zolusa sizidzaphonya oimira osiyanasiyana a invertebrates, mollusks ndi zina zotero.
Njira zophera nsomba
Chifukwa cha kuchuluka kwa zamoyo, zaukali komanso kuphulika, ndizomwe zimachitika pafupipafupi komanso zomwe zimasodza pamitsinje yamadera otentha a mitsinje ya South America. Kugwira ma piranha pa nyambo zachilengedwe sikufuna zida zapadera, chidziwitso ndi luso. Ambiri aonapo zithunzi za anthu akumeneko akugwira piranha popanda ndodo kapena mbedza, pogwiritsa ntchito mitembo ya nyama kapena nsomba. Kuchokera ku umbombo, ma piranha amamiza mano awo m'thupi, ndikukhalabe akulendewera pamenepo, mumangofunika kulinyamula ndikuliponya kumtunda. Nyama ya nsomba ndiyokoma kwambiri ndipo imagwiritsidwa ntchito mwachangu ngati chakudya. Mukawedza ndi ma nozzles osiyanasiyana pogwiritsa ntchito zida za amateur, ndikofunikira kugwiritsa ntchito ma leashes amphamvu, mwina waya wachitsulo wamba. Ma leashes amafunikira, ngakhale atagwira ma piranhas a herbivorous. Asodzi ambiri amene amabwera ku mitsinje yotentha ya ku America amayesa kugwira mitundu yosiyanasiyana ya nsomba. Ndipo, monga lamulo, ma piranhas omwe amapezeka paliponse amakhala "vuto": chifukwa cholumidwa pafupipafupi, zimakhala zovuta kuyang'ana woimira wosankhidwa wa ichthyofauna. Njira zodziwika kwambiri zophatikizira ma piranha zitha kuonedwa ngati usodzi ndi zida zosiyanasiyana pogwiritsa ntchito nyambo zachilengedwe. Njira yachiwiri yodziwika bwino ya usodzi wa amateur ndikupota.
Kugwira nsomba pandodo yopota
Monga tanenera kale, kugwira ma piranhas pa kupota nthawi zambiri kumalumikizidwa ndi kuwagwira ngati kusaka. Ngati mukufuna kusodza mapiranha mwadala, ndiye kuti chofunikira kwambiri pazida ndi mphamvu zake. Choyamba, izi ndi leashes ndi mbedza. Monga tanenera kale, leash yodalirika kwambiri ikhoza kukhala chidutswa cha waya wachitsulo. Chifukwa chake ndi chomveka - mano ambiri akuthwa omwe amatha kuwononga mafupa aliwonse. Kupanda kutero, njira zopangira nyambo ndi zida zomwezo ndizogwirizana kwambiri ndi zomwe zimachitika munthu wopha nsomba ndi zilakolako zake. Poganizira kuti mitundu ikuluikulu ya ma piranha ndi nsomba zazing'ono, zida zopota zamagulu opepuka zitha kugwiritsidwa ntchito pakusodza mwapadera. Koma musaiwale kuti nsomba zambiri m'mitsinje yotentha ndizomwe zimayambitsa kulumidwa kosayembekezereka, komwe m'malo mwa piranha yaying'ono, nsomba yolemera ma kilogalamu angapo imatha kuluma.
Nyambo
Nyambo yayikulu yogwirira ma piranhas ndi nyambo zachilengedwe zochokera ku nyama. Pankhani ya kusodza ndi nyambo zopangira, kusankha kuyenera kukhazikitsidwa pa mfundo yamphamvu kwambiri. Kapena, usodzi ukhoza kukhala "zosintha zopanda malire" za nyambo. Kuti agwire mitundu yosadya nyama, anthu am'deralo nthawi zambiri amagwiritsa ntchito zipatso za zomera, zomwe nsomba zimatha kudyetsa.
Malo ausodzi ndi malo okhala
Ndizofunikira kudziwa kuti banja la piranha lili ndi oyimira osachepera 40, ndipo mwina pali mitundu yosadziwika. Malo ogawa amakhudza madera akuluakulu a mitsinje ndi nyanja zotentha ku South America: Venezuela, Brazil, Bolivia, Argentina, Colombia, Ecuador ndi mayiko ena. M'mitsinje amamatira kumalo osiyanasiyana, koma kawirikawiri amakhala m'madzi othamanga. Ziweto zimayenda mwachangu m'mphepete mwa dziwe.
Kuswana
Makhalidwe obereketsa a piranha ndi osiyanasiyana. Mitundu yosiyanasiyana imabala nthawi zosiyanasiyana. Zimadziwika kuti piranhas amadziwika ndi masewera aatali asanayambe kubereka, kumene awiriawiri amapangidwa. Amuna amakonzekera malo oberekera ndipo amateteza mwaukali kumanga. Akazi a Piranha amabereka kwambiri: amayikira mazira masauzande angapo. The makulitsidwe nthawi zimadalira m'deralo kutentha zinthu mosungira.
