Ndi zinsinsi ndi zinsinsi zingati zomwe zimasungidwa muufumu wamadzi. Asayansi sanaphunzire mokwanira nzika zake zonse. Mmodzi mwa oimira owoneka bwino kwambiri a nsomba zozizwitsa ndi shark wokazinga, kapena amatchedwanso shark corrugated.
Makhalidwe ndi malo okhala shark wokazinga
Mu 1880, L. Doderline, katswiri wazachthy ku Germany, adapita ku Japan, ndipo paulendowu adakhala woyamba kupeza Shaki yokazinga. Pambuyo pake, atafika ku Vienna, wasayansi uja anafotokoza mwatsatanetsatane za nsomba yachilendo imeneyi.
Tsoka ilo, ntchito zake zonse sizinapulumuke mpaka pano. Patatha zaka zisanu, katswiri wazanyama waku America a Samuel Garman adasindikiza nkhani. Inalankhula za nsomba yachikazi, pafupifupi pafupifupi mita ziwiri, yomwe inagwidwa ku Gulf of Japan.
Kutengera mawonekedwe ake, aku America adaganiza zomupatsa dzina loti toled. Pambuyo pake, adapatsidwa mayina enanso angapo, monga lizard shark, silika ndi yokazinga selachia.
Monga tawonera chithunzi, m'mbali mwa mutu nsomba yokazinga, pali nembanemba wa gill intersecting pakhosi. Zilonda za gill zokutira izi zimapanga khola lalikulu lomwe limawoneka ngati chovala. Chifukwa cha izi, nsombazi zidadziwika.
Miyeso, akazi nsomba yokazinga amakula mpaka mita ziwiri m'litali, zazimuna ndizochepa pang'ono. Amalemera pafupifupi matani atatu. Kunja, amawoneka ngati njoka yaku Basilisk yoopsa kuposa nsomba.
Thupi lawo limakhala lakuda bulauni komanso pambali pake, pafupi ndi mchira, pali zipsepse zozungulira. Mchira womwewo sunagawike magawo awiri ngati nsomba, koma mawonekedwe amakona atatu. Chimawoneka ngati tsamba limodzi lolimba.
Palinso zochititsa chidwi pakapangidwe ka thupi la nsombazi, msana wawo sunagawike m'mafupa. Ndipo chiwindi ndichachikulu, kulola nsomba zam'mbuyomu kuti zizikhala pansi penipeni, popanda kupsinjika.
Nsombayi ili ndi mutu waukulu, wotambalala komanso wolimba, wokhala ndi mphuno pang'ono. Mbali zonse ziwiri, kutali wina ndi mnzake, pali maso obiriwira, pomwe zikope zawo kulibiretu. Mphuno zili pamtunda, mwa mawonekedwe a mapangidwe awiri.
Likukhalira kuti mphuno iliyonse imagawidwa pakati ndi khola la khungu, polowera ndi kubwerekera. Ndipo nsagwada za nsombazi zimapangidwa mwanjira yoti zitha kuzitsegula mwamphamvu ngati mphezi mpaka kumeza nyamayo. Pakamwa pa nsomba zozizwitsa zimamera m'mizere, mano pafupifupi mazana atatu ndi asanu osongoka, owoneka ngati mbedza.
Shaki wokazinga amawoneka ngati njoka osati mawonekedwe ake okha. Imasaka mofanana ndi njoka, poyamba imapanikiza thupi lake, kenako mosadabwitsa imalumpha kupita kutsogolo, kumenya wovulalayo. Komanso, chifukwa cha kuthekera kwakuthupi kwa matupi awo, amatha kuyamwa mwawomwe amatanthauza.
Shaki yokazinga imakhala m'madzi a Pacific ndi Pacific Ocean. Alibe kuya kwakanthawi komwe amakhala. Ena adaziwona pafupifupi pamadzi pomwepo, pamtunda wa mamita makumi asanu. Komabe, mwamtendere mwamtheradi komanso osavulaza thanzi lake, amatha kutsika mpaka kilomita imodzi ndi theka.
Mwambiri, mtundu uwu wa nsomba sunaphunzire mokwanira. Ndizovuta kuigwira, nthawi yomaliza pomwe nsomba yozemba idagwidwa zaka khumi zapitazo ndi ofufuza ochokera ku Japan. Nsombazo zinali pafupi pomwepo pamadzi ndipo zinali zitatopa kwambiri. Anayikidwa mu aquarium, koma sakanakhoza kukhala ndi moyo mu ukapolo, adamwalira posachedwa.
Chikhalidwe ndi moyo wa shark wokazinga
Sharki wokazinga samakhala awiriawiri kapena mapaketi, amakhala okha. Shark amathera nthawi yawo yambiri mozama. Amatha kugona pansi kwa maola ambiri ngati chipika. Ndipo amapita kukasaka usiku.
Chofunikira pakukhalapo kwawo ndikutentha kwamadzi momwe akukhalamo, sikuyenera kupitilira madigiri khumi ndi asanu Celsius. Pakatentha kwambiri, nsomba zimakhala zosagwira ntchito, zofooka kwambiri, ndipo zimatha kufa.
Shaki imasambira pansi pa nyanja, osati mothandizidwa ndi zipsepse zake. Amatha kupindika thupi lonse ngati njoka ndikusunthira bwino komwe amafunikira.
Ngakhale shark wokazinga amakhala ndi mawonekedwe owopsa, ndiye, monga ena onse, ali ndi adani ake, ngakhale kulibe ambiri. Awa akhoza kukhala nsombazi zazikulu ndi anthu.
Zakudya zabwino
Shaki yokhala ndi ziphuphu ili ndi katundu wodabwitsa - mbali yotseguka. Ndiye kuti, amasaka pansi penipeni mumdima, akumva mayendedwe onse omwe nyama yake imatulutsa. Amadyetsa nsomba yokazinga nyamayi, mbola, nkhanu ndi ena onga iwo - nsombazi zazing'ono.
Komabe, zimakhala zosangalatsa kudziwa momwe munthu wokhala pansi ngati shaki wokazinga amatha kusaka nyamayi mwachangu. Lingaliro lina lidakhazikitsidwa pankhaniyi. Amati nsombazi, zitagona pansi mumdima wandiweyani, zimakopa nyamayi ndikuwonetsa mano ake.
Ndipo kenako amamuwukira mwamphamvu, akumukwapula ngati mphiri. Kapenanso potseka ma slits pamiyala, pakamwa pawo pamakhala vuto linalake, lomwe limatchedwa kuti negative. Ndi chithandizo chake, wovulalayo amangoyamwa mkamwa mwa nsombazi. Nyama zosavuta zimapezekanso - squids odwala, ofooka.
Shaki wokazinga samatafuna chakudya, koma amameza chonse. Mano akuthwa, opindika mkati mwake kuti agwire mwamphamvu nyama.
Pomwe amaphunzira za nsombazi, asayansi adazindikira kuti kummero kwawo kumakhala kopanda kanthu. Chifukwa chake, pali malingaliro kuti mwina amakhala ndi nthawi yayitali pakati pakudya, kapena dongosolo lakugaya chakudya limagwira ntchito mwachangu kwambiri kotero kuti chakudya chimasegulidwa nthawi yomweyo.
Kubereka ndi chiyembekezo cha moyo
Palibe chidziwitso chochepa chokhudza momwe nsomba zowotchera zimaswana. Amadziwika kuti kukhwima mwa kugonana kumachitika akakula pang'ono kupitirira mita.
Chifukwa chakuti nsombazi zimakhazikika kwambiri, nyengo yawo yokwatirana imatha kuyamba nthawi iliyonse pachaka. Amasonkhana m'magulu momwe kuchuluka kwa amuna ndi akazi kuli kofanana. Kwenikweni, magulu oterewa amakhala ndi anthu makumi atatu mpaka makumi anayi.
Ngakhale zazikazi za nsombazi zilibe pulacenta, komabe, ndi viviparous. Sharki samasiya mazira ake pa algae ndi miyala, monga momwe nsomba zambiri zimachitira, koma amadzipangira okha. Nsombayi ili ndi mazira awiri ndi chiberekero. Amakhala ndi mazira ndi mazira.
Makanda osabadwa amadya yolk sac. Koma pali mtundu womwe mayi mwiniwake, mwanjira ina yosadziwika, amaperekera ana ake m'mimba.
Pakhoza kukhala mazira khumi ndi asanu omwe amera. Likukhalira mimba yokazinga Shaki Imakhala zaka zopitilira zitatu, imadziwika kuti ndiyo yayitali kwambiri pakati pa mitundu yonse yazinyama.
Mwezi uliwonse, mwana wamtsogolo amakula sentimita imodzi ndi theka, ndipo amabadwa kale theka la mita. Ziwalo zawo zamkati zimapangidwa mokwanira ndikukula kotero kuti amakhala okonzeka kukhala moyo wodziyimira pawokha. Zikuoneka kuti nsombazi zimakhala zaka zopitilira 20 mpaka 30.
Nsomba zokazinga sizikuwopseza anthu. Koma asodzi sawakonda kwambiri ndipo amawatcha tizirombo chifukwa amathyola maukonde. Mu 2013, mafupa a pafupifupi mamitala anayi adatoleredwa.
Asayansi ndi ichthyologists anaphunzira kwa nthawi yayitali ndipo anazindikira kuti ndi ya shark yakale kwambiri, yayikulu kwambiri. Pakadali pano, nsombazi zimasungidwa mu Red Book ngati nsomba zomwe zili pangozi.
