Mbalame yotchedwa red shark (Shroederichthys chilensis), yomwe imadziwikanso kuti Chile shark cat, ndi yayikulu kwambiri ya shark, class -fish cartilaginous.
Kufalitsa kwa red-spotted cat shark.
Shaka wofiira yemwe amakhala ndi khungu lofiira amakhala m'madzi agombe kuchokera pakati pa Peru kumwera kwa Chile mpaka kum'mawa kwa Pacific Ocean. Mitunduyi imapezeka m'madera amenewa.
Malo okhala mphaka wa malo ofiira ofiira.
Nsombazi zimapezeka mdera lamiyala pamphepete mwa alumali. Kugawidwa kwawo kumawoneka ngati kwakanthawi, m'malo amiyala nthawi yachilimwe, chilimwe ndi nthawi yophukira, komanso nthawi yozizira m'madzi akuya kwambiri. Amakhulupirira kuti kusunthaku kumachitika chifukwa champhamvu m'nyengo yozizira. Nsombazi zimapezeka m'madzi kuyambira mita imodzi mpaka makumi asanu kuya. M'mbali mwa nyanja, pakuya kwa 8 mpaka 15 m mchilimwe komanso kuyambira 15 mpaka 100 m m'nyengo yozizira.
Zizindikiro zakunja za mphaka wa khungu lofiira.
Shaka wofiira yemwe amakhala ndi khungu lofiira amakula mpaka kutalika masentimita 66. Kutalika kwa thupi la mkazi kumayambira 52 mpaka 54 cm, wamwamuna - kuyambira 42 mpaka 46 cm.
Mitundu iyi ya shark imakhala ndi thupi losalala, lofanana ndi banja lonse.
Ali ndi mipata isanu yaboma, ndikutsegulira kwachisanu komwe kumakhala pamwamba pazipsepse za pectoral. Amakhala ndi zipsepse ziwiri zakuthambo zopanda mitsempha, chimaliziro choyamba chakumtunda chomwe chili pamwambapa. Palibe pafupifupi bend yakumtunda.
Shaka wamphaka wofiira amakhala ndi utoto wakuda ofiira kumbuyo ndi mimba yotuwa yoyera. Ali ndi mawanga akuda pansi pa thupi komanso pamadontho ofiira akuda m'malo oyera.
Kuchuluka kwa mano pakati pa amuna nthawi zambiri kumakhala kokulirapo ndi mavavu ochepa, omwe amaganiziridwa kuti ndiofunikira kuti "azing'amba" akazi nthawi ya "chibwenzi".
Kubalana kwa mphaka wa khungu lofiira.
Shaka wofiira yemwe amakhala ndi khungu lofiira amaberekana nyengo yake, ndimagulu azikhalidwe zosiyana omwe amapezeka nthawi yachisanu, masika ndi chilimwe pafupi ndi San Antonio, Chile, Farinha ndi Ojeda. Komabe, nthawi zina, nsombazi zazimayi zimayikira mazira mchaka chonse.
Nsombazi zimakhala ndi chizolowezi chocheza panthawi yokwatirana, momwe yamphongo imaluma mkazi kwinaku ikutulutsa mazira.
Sharki ndi oviparous, ndipo mazira obereketsa nthawi zambiri amatuluka mu oviduct. Amatsekedwa mu kapisozi, kapisozi iliyonse nthawi zambiri imakhala ndi mazira awiri. Mazira amakula chifukwa cha yolk. Nsombazi zazing'ono zimawoneka kutalika kwa 14 cm, ndimakope ang'onoang'ono a shark achikulire ndipo nthawi yomweyo amakhala odziyimira pawokha, ndikupita kumadzi akuya. Mwachangu amaganiziridwa kuti amasambira m'madzi akuya kwambiri kuti apewe kuwonongedwa mdera laling'ono ndikubwerera kumalo awo akadzakula. Chifukwa chake, pali kusiyana pakati pa akulu ndi achichepere, omwe amakula. Shaka wofiira yemwe ali ndi malo ofiira amakula mwachangu, koma zaka zakutha msinkhu sizidziwika. Zaka zakutchire sizinakhazikitsidwe.
Khalidwe la mphaka wofiira.
Nsombazi zimakhala ndi nsomba zokhazokha. Amayenda usiku, amakhala m'mapanga ndi ming'alu masana ndikutuluka usiku kukadya. M'miyezi yachisanu amalowa m'madzi akuya, mkati mwa chaka chonse amayenda m'mphepete mwa alumali. Kusunthaku kumakhulupirira kuti kumalumikizidwa ndi mafunde amphamvu panthawiyi. Nsombazi zimakhala ndi fungo labwino komanso zimalandila zamagetsi, mothandizidwa ndi nsomba zomwe zimazindikira mphamvu zamagetsi zomwe nyama zina zimatulutsa, komanso zimazolowera maginito.
Amphaka amphaka adatchulidwa ndi kupezeka kwa mwana wowoneka wowongoka wamaso. Iwo ali ndi masomphenya abwino ngakhale mu kuwala kochepa.
Kudyetsa nsombazi.
Nsombazi zimadya nyama zakutchire zosiyanasiyana. Chakudya chawo chachikulu ndi nkhanu ndi nkhanu. Amadyanso mitundu ingapo ya nkhanu zina, komanso nsomba, algae, ndi nyongolotsi za polychaete.
Ntchito yazachilengedwe ya mphaka wofiira.
Nsombazi zimakhala ndi malo ofunikira m'zakudya zawo. Zowonongekazi zimayang'anira kuchuluka kwa zamoyo zam'magawo a benthic m'mbali mwa nyanja.
Shark ndi omwe amanyamula tiziromboti tambiri, kuphatikizapo leeches, trypanosomes. Trypanosomes amasokoneza magazi a nsomba ndipo amagwiritsa ntchito matupi awo monga wolandila wamkulu.
Kutanthauza kwa munthu.
Akatswiri ofufuza amphaka ofiira ofiira ndiomwe amafufuza asayansi omwe amachitika m'ma laboratories, amamugwirira kuti akafufuze, chifukwa chake nsomba za nsombazi zingakhudze kukula kwa anthu ang'onoang'ono, am'deralo. Koma ndizovulaza asodzi ogulitsa mafakitale ku Chile ndi ku Peru, chifukwa amadya nyama zakutchire, zomwe ndizofunika kwambiri pachuma m'maiko ena.
Malo osungira mphaka wofiira.
Pali chidziwitso chochepa kwambiri pamanambala a anthu komanso zoopseza mitundu iyi kuti ilowe mu sharki wamabala ofiira pa Red List. Amagwidwa ngati nsomba zambiri mwa nsomba, m'mphepete mwa nyanja, pansi ndi patali. Sizikudziwika ngati nsombazi amakhala ndi chiopsezo kapena ali pangozi. Chifukwa chake, palibe njira zotetezera zomwe zagwiritsidwa ntchito kwa iwo.
