A nsomba thanki: kufotokoza

M'nkhaniyi, ife tipeza zomwe nsomba thanki (placoderms). Kumene mwachibadwa zikachitika, kaya akhoza kukhala mu Aquarium kunyumba, pambali, ngati iye akanakhoza kukhala ndi nsomba zina ku dziwe ambiri?

A dunkleosteus thanki nsomba

Dunkleosteus - thanki ndi nsomba zinatha, amene amadziwika ku zigaza, amene zaka zaka miliyoni 360. mitembo yawo anazipeza Cleveland, Ohio, Tennessee, Pennsylvania, California. Other dunkleosteidy anapezeka ku Russia, Poland, Morocco, Belgium.

Dunkleosteus akunja wandiweyani anali TACHIMATA mbale. Ngakhale, mosiyana ndi ena placoderms, thupi lake yosalala zida si onse ataphimbidwa, koma mbali yaing'ono chabe ya mutu kutsogolo pamodzi. Kukhala enieni, mu ndondomeko ya kusinthika kwa zinthu ndi mbali dorsal la mbale pang'ono adzafupikitsidwa, pamene ena onse thupi anakhalabe mfulu kwa iwo, pamenepo kupereka ufulu akamagwiritsa, ndipo pofuna kupanga kukhala liwiro yabwino.

The pectoral zipsepse anali kutali m'mbali, monga nsombazi a. Mwina ndi protrusion wa chipsyepsye kumbali ya kuposa theka m'lifupi thupi nsomba. Mu zipsepse pectoral arthrodires contours anali ofanana ndi contours ya chipsyepsye chichereŵechereŵe Paleozoic. Mwina, linalinso ndi dongosolo ofanana wa zipsepse m'chiuno.

mafotokozedwe

Nsomba thanki Pike (garfish) akukhala mu mtsinje wa Central ndi North America, komanso mu Caribbean. Izo wakonda madzi pang'ono brackish kapena mwatsopano. Nthawi zambiri, koma izo zifika kudutsa ndi m'nyanja.

Akatswiri ena amati A nsomba thanki padziko lathuli ankakhala m'nyengo Cretaceous - zaka 200 miliyoni zapitazo. Mu America ndi ku Ulaya, zotsalira za nsomba anapezeka. Panthawi pano mu dziko pali 7 mitundu ya Pike.

nsomba oti muli nazo zida, zithunzi zimene zili m'nkhani ino, kukula kwa kukula chidwi. Ngakhale kwambiri zitsanzo lalikulu n'zochepa. Lalikulu Pike thanki ukufika makilogalamu 130, ndipo pa atatu mamita m'litali. chikuoneka limafanana khalidwe kwathunthu - iye ndi ankakwiya ndi mmene anthu am'deralo kunena, ndi woopsa. Chilombo polimbana ndi nsomba zina ndi mano lakuthwa kukumba mu mutu wovulalayo, kenako uyo izo. Zitatero mkaziyo anabwerera kwa thupi la nyama zawo kuti tipitirize chakudya. Pali milandu ngakhale kuukira nsomba pa munthu.

ntchito

A thanki mu chakudya nsomba ntchito infrequently, koma nyama yake ndi edible ndithu. Mu ena misika ku Central America angapezeke mu msika. Chidwi kwambiri ndi garfish kwa anglers masewera anadzipereka kugwira nyama zosiyanasiyana zosowa. M'pofunika kuvomereza, zimphona izi sizingagwire aliyense. Ndipo kum'peza mu yaing'ono amatunga atachuluka zovuta. Chifukwa chake ndi yekhayo wodziwa angler.

Brigandine mabanga Pike

A nsomba thanki amatchedwanso Umboni Wopereŵera billfish. Ndi nsomba zolusa. Chimakula kwa 1.2 mamita Yaikulu kulemera kudziwika -. Makilogalamu 4.4. Kutalika kwa moyo wake - zaka pafupifupi 18. wachikuda za thupi kukhala mitundu ingapo - kuchokera bulauni kuwala maolivi mithunzi. Iwo Tingaone Chithunzi Madontho mdima mithunzi. mbali kumbuyo kwa mbandakucha pang'ono, ndipo mimba ndi pafupifupi woyera. Pang'ono anamaliza caudal chipsyepsye. The dorsal ndi zipsepse kumatako ndi lopangidwa ndi kunyezimira zisanu ndi zinayi kapena zisanu ndi ziwiri.

Miyoyo nsomba Mississippi ndi mitsinje ina, amene kumadzulo kwa Florida Noeses kuyenda mu Gulf of Mexico. Iwo amasankha madzi brackish.

A thanki Aquarium Pike

Panthawi ino woimira ogwirira sizachilendo. A nsomba thanki mu m'chere zokhala m'malo owetera lalikulu kwa masentimita 30 m'litali. Mu muli yaing'ono Pike ngati msanga Kusiya kukula mu Volume ndi kukula.

Onga iwo molimba monga mwala. Iwo slanting mizere, ndipo anati mawonekedwe ake kukongoletsa plitochki. Nsomba mbedza ngati ikhale pamphuno, ndi yaitali, zibwano yopapatiza tizinthu ndi nambala yaikulu mano.

mbali structural

nsomba amakhala ndi yachilendo dongosolo anatomical. Iye vertebrae alibe matendawa, mbali zonse, azipereka nsomba otsala. Iwo ali mbali imodzi recessed ndi otukukira kunja - pa ena. kapangidwe ndi zina zambiri achule. Mu Pike crustacean chikhodzodzo kusambira ali nawo ntchito kupuma.

Izi limodzi lalikulu chitsanzo, oyenera yaikulu ndi capacious chionetsero Aquarium. Nsomba ndi chidwi akatswiri likuvutika kufanana kunja ndi alipidwa pafupifupi Pike European. Kunyumba, kawirikawiri muli nsomba palibe akulu, ngakhale kuti ndi mwamakani zokwanira anthu onse a thanki.

okhutira

Panthawi pano pali chizolowezi chakuti kunyumba lili nsomba zimene zimadya. Ambiri amakhulupirira kuti kuyang'ana kwa anthu kakang'ono ndipo mtendere wa dziko m'madzi ndithu wotopetsa. Ngakhale zimadya nsomba zazikulu, amakonda izo - chidwi. Connoisseurs kuzindikira zosowa brash chikhalidwe ndi kuwonetseredwa mokwiya.

A nthumwi otchuka wa dera ndi Aquarium amazipanga wotchuka wokhala thanki A imatengedwa ndi Pike. Nyumba kufika 30 masentimita pamafunika Aquarium opanda malita zosakwana 150. Mu mdani uyu zamitundu zimadalira mwachindunji pa magawo a nyumba yake. Pa Aquarium ndi ankaona wotchuka thanki mabanga Pike.

nsomba amakonda kukhala pamwamba pa madzi. Anansi ake makamaka ikuluikulu. Iwo amakhala mu zigawo m'munsi - izo zimawathandiza mwamtendere azikhala ndi chilombo, pamaso ife.

Zofunika kwa Aquarium madzi ndi

Timauzidwa kuti tiyenera Aquarium lalikulu zili nsomba. Ngati mukufuna kukula kukula kwake makamaka lalikulu, muyenera "dziwe", kuchuluka amene si malita zosakwana 500. Madzi Choncho ayenera kukhala otsatirawa: ndi stiffness - DH 17 kutentha - 20 ° C, acidity - pH 8.

Zili ngati kuvomerezedwa kusefera Pike madzi ndi aeration. Chipinda ayenera kukhala pang'ono - nsomba n'kofunika kwambiri kuposa malo ufulu kusambira.

chakudya

aquarists odziwa kuti ogwirira izi amadwala kusafuna kudya. Iwo kudya nsomba yaing'ono ndalama zosaneneka. M'mawu ena, thanki amazipanga voracious Pike. Choncho, kusamalira eni zambiri mungazipeze zodyetsedwa bwino Aquarium toyesa, nthawi zina chokhala chipika akuyandama. Chifukwa cha dyera la nsomba safuna kuti awasunge pamodzi ndi anthu angapo.

Pomaliza ...

Si kale mu umodzi wa mapulogalamu a pa TV phungu wa sayansi mankhwala Sandomirskiy Mark ananena kuti miyala ya nthawi Devonian pali nkhokwe yaikulu maganizo mphamvu zowononga kuti wasiya anthu akaponya chikumbumtima oti muli nazo zida nsomba, woimira ngozi yaikulu kwa anthu. kutengerapo unachititsa ambiri mbiri, nkhani ndi kwenikweni kunyozedwa.
