Namwino shark

Kamwa kakang'ono

Lero tikambirana za nsombazi zomwe zilibe vuto lililonse kwa anthu ngakhale zikuwoneka. Zake za namwino shark. Dzinalo lake lasayansi ndi Ginglymostoma cirratum ndipo ndi mtundu wopanda phokoso. Ndi gawo la banja la Ginglymostomatidae, momwe zojambulazo zimapezeka pansi pa nyanja pomwe kuwala kumakhala kocheperako komanso kukhala kovuta. Chodabwitsa kwambiri pa nyamayi ndikuti ili ndi pakamwa pocheperako kuposa nsomba zonse.

Munkhaniyi tiwuza biology yonse, machitidwe, kudyetsa ndi kubereka kwa namwino shark.

Makhalidwe apamwamba

Namwino shark ndi wautali pafupifupi mita inayi. Ndi nyama yomwe imagona usiku ndipo nthawi zambiri imapuma kunyanja m'mapanga abwino masana. Nthawi yomwe imadyetsa ndi usiku ikapita kukasaka. Mosiyana ndi shark wamba, namwino shark ali ndi kamwa yaying'ono kwambiri. Ali ndi mtundu wakuda yunifolomu yocheperako ndipo mitundu ina imakhala ndi zotumphukira.

Mwambiri, zimawoneka kuti ndi zonenepa. Monga tanena kale, ndi nyama yosavulaza ngakhale kuti imawoneka. Komabe, imatha kuukira ngati ikumva kukwiya ndi nyama kapena munthu. Akaluma, Amagwiritsa ntchito nsagwada zawo kuti azitseke mwamphamvu ndipo ayenera kukakamizidwa kuti atsegulenso. Ngati mukufuna kuyesa kuchotsa china chake chomwe namwino shark anali kudya ndi chinthu chosatheka.

Zomwe zimagwirizana ndi ma shark ena onse ndikuti ili ndi ma gill slits omwe sanawululidwe ndipo alibe kusambira chikhodzodzo. Izi zimalipidwa chifukwa chokhala ndi chiwindi chachikulu m'chiwindi. Chiwindi ndi chachikulu kwambiri komanso ndi mafuta ambiri.

Mtundu ndi malo okhala

Namwino shark m'chilengedwe chake

Namwino shark ali ndi malo osiyanasiyana omwe amapezeka m'nyanja zotentha. Chizindikiro choti malowa ndi omwe amawakonda ndikuti amapezeka kwambiri pagombe la Central America. Osati pachifukwa ichi, gawo lawo logawika latsekedwa m'malo awa, komanso amapitilira magawo ena akumpoto monga New York. Kumene kuli shaki zambiri zamankhwala padziko lapansi kuli kuzungulira kontinenti yaku America m'nyanja zonse za Pacific ndi Atlantic.

Ponena za malo ake Titha kuzipeza pakuya kwa mita 70 komanso pamtunda wamchenga komanso wamatope.

Khalidwe

Ngakhale zikuwoneka zowopsa, namwino nsombazi sizikhala zaukali konse pokhapokha zikawona kuti zikuwopsezedwa kapena kuwononga malo ake. Mwachitsanzo, pakhala pena pomwe pakamwa pake pakhala pali potsekedwa mwamagetsi ndipo kuti atsegule, titanium forceps yakhala ikugwiritsidwa ntchito ndipo wagwiritsa ntchito mphamvu zambiri. Alibe vuto chifukwa m'malo ena okhala m'nyanja zam'madzi zoyeserera zina akhala akugwiritsidwa ntchito kuti alendo azikwera. Chizolowezi chomwe ali nacho pamakhalidwe awo ndichosachita chidwi.

Kudyetsa ndi kubereka kwa namwino shark

namwino shark akusambira

Zachidziwikire ambiri amadabwa momwe nsombazi zimadyera ngati pakamwa pazo ndizocheperako. Pofuna kuthana ndi vutoli, nsombazi zimagwiritsa ntchito njira yodyetsera yomwe imayamwa ma crustaceans ndi mollusks kuti pambuyo pake iwaphwanye ndi mano ake opindika komanso akuthwa. Mollusks ndi crustaceans ndiwo amapanga zakudya zambiri za namwino shark.

Amathanso kudya nkhaka ndi oyisitara omwe amawapeza akuyenda usiku.

Ponena za kubereka kwake, ndi chimodzimodzi ndi mitundu yonse ya nsombazi. Kukwatana kwawo ndi umuna wawo ndi wamkati. Poterepa tili ndi kuberekana kwa ovoviviparous. Ndiye kuti, akazi amatha kusunga mazira mkatimo ndipo mazirawo amadyetsa okha ndi zakudya zomwe mayi angawapatse.

Kuti kukwatira kuchitike kuyenera kuchitidwa m'madzi osaya. Mukugona kulikonse amatha kupanga pakati pa 21 ndi 28 achichepere. Kuyambira pomwe ana amasiyanitsidwa ndi amayi awo ayenera kukhala odziyimira pawokha. Kuphunzira kudzilima wekha ndikofunikira kwambiri ngati mukufuna kukhala ndi moyo wabwino. Sizachilendo masiku ochepa atangobadwa kuwona machitidwe akudya nyama zakutchire kuti athetse njala yomwe ikukula komanso chilakolako cha magazi.

Nurse shark chidwi

kusaka nsombazi

Mwa zina zomwe nsombazi zili nazo, titha kuwona kuti, ngakhale ndi nyama yamtendere kwambiri komanso yopanda vuto lililonse, ndiyamtunda kwambiri. Amatha kukhala mdera lina mpaka zaka zinayi. Nthawi zina zimawoneka ngati zankhanza kwa mitundu ina kapena anthu ena omwe amafika kudera lomwe amakhala. Akamukonda, adabadwa, ngati sachoka kwa amayi ake mwa iye yekha patadutsa sabata limodzi, atha kukhala mayi yemweyo yemwe amamaliza kudya.

Amatha kumva magazi a nyama zina kuchokera pamtunda wopitilira makilomita asanu. Kutengera mtundu wa mafunde apanyanja panthawiyo, mtunda uwu ukhoza kukhala wokulirapo.

Pokhala mtundu wopanda vuto kwa anthu, amadziwika kuti ali pachiwopsezo. Chiwerengero cha nsombazi chomwe chimasakidwa mosavomerezeka chifukwa cha kuchepa uku ndi kwakukulu. Mlandu wapadera womwe udachitika pa June 15, 2009 udapangitsa kuti mabungwe azamalonda azinyama asokonezeke nawo. Poterepa, panali kutumiza kwa zidebe 20 zamamitala khumi ndi awiri mulitali zomwe zidachoka padoko la Yucatan kupita ku Spain. Kutumiza uku kudayimitsidwa ndi apolisi ndipo adapezeka kuti adadzazidwa ndi shaki wachisoti wachisanu mkati. Choyipitsitsa, ndikuti mkati mwa anamwino achisanu shark munali pafupifupi 200 kg ya cocaine.

Akatswiri amanena kuti kusaka kwakukulu kwa nyamazi kungayambitse mavuto aakulu m'nyanja. Izi ndichifukwa chakukhudzidwa komwe nyama zomwe zagwidwa zimatulutsa munthawi ya chakudya.

Ndikukhulupirira kuti ndi chidziwitsochi mutha kuphunzira zambiri za namwino shark.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
