Nkhanu - izo decapods

chilengedwe ichi zachilengedwe ali ndi maonekedwe chochititsa. Nkhanu - ndi denizen ya dziko la madzi ndi osangalatsa kuonera khalidwe lawo mu chigoba pamadzi Mwachitsanzo, mu madzi otentha. Ngati Muziganiza zobiriwira algae, nkhanu izi kuyambira ndilumphepo ngati ziwala udzu.

Nkhanu. tanthauzo

Nyama imeneyi ndi optimally ndinazolowera zikhalidwe za moyo mu nyanja, zomwe mosakayikira anakhudzidwa matabwa ake. Nkhanu - ndani izi? Crustacean a dongosolo Decapoda (pali okwana genera 250 ndipo pafupifupi 2000 mitundu). Caridea (wotchedwa anthu a m'nyanja ndi m'nyanja m'njira sayansi) ndi ubiquitous nyanja ndi nyanja, angapezeke ngakhale ena amatunga madzi atsopano, mitundu ambiri osiyanasiyana amene timapemphera mu madzi otentha. Wochuluka Nyanja Black, Nyanja ya Azov. Ku funso "Chiswamphika - ndi nyama kapena ayi?" - yankho unambiguously zabwino, monga arthropods onse ali mamembala a nyama.

kapangidwe

Elongated pamodzi kutalika kwa thupi pang'ono flattened pa mbali. Iwo agawidwa zigawo zikuluzikulu ziwiri: pamimba, cephalothorax. Chigawo chachiwiri ndi theka la thupi lonse. Kumayambiriro kwa cephalothorax chipolopolo ali awiri maso kuti ali mu maenje wapadera. Cephalothorax amateteza chitinous chipolopolo, zovuta ndi cholimba, anapanga mbale awiri ndi Ufumuyo makutu a. Koma mmunsi mwa chipolopolo ndi yofewa. Makulidwe amitundumitundu kuyambira 2 30 masentimita.

chiwalo cha masomphenya

Nkhanu - nyama zachilendo kuti ali ndi masomphenya osiyana: usana ndi usiku. Aliyense wa maso ake wapangidwa ndi chiwerengero chachikulu cha mbali, koma msinkhu, chiwerengero chawo ikukula. Faceted zigawo anapambulwa mawanga pigment. Ndipo wachina chilichonse amatenga cheza amene amagwa perpendicularly kwa diso ndi. Amenewa masomphenya angatchedwe ndi zithunzi. Characteristically, mu usiku nthawi tsiku inki kumwazikana mu m'munsi mwa diso, ndi kunyezimira slanting imakhala diso: ndi nkhanu amaona zinthu kale zonse, koma maphunziro awo ali amaona.

Nkhanu - izo decapods

Ngakhale kuti zolengedwa nyanja ndi n'chinthu chofunikira dongosolo la decapod zoona, ali ochuluka monga naintini awiriawiri miyendo. Ndipo aliyense udindo kwa kuchitapo kanthu. Tinyanga Mwachitsanzo, ntchito kukhudza, ndi wochepa thupi ndi miyendo yaitali, mapeto a amene ali pincers ang'ono kugwira ntchito yeniyeni - ndi thandizo lawo nyama aisadza thupi lanu ndi makutu, ngati yatsekera. miyendo Other ntchito ndi kayendedwe pamodzi pansi, iwo amakhala akuluakulu ndi yaitali kuposa ena. A miyendo pamimba ntchito pamene crustacean kuti kusambira. Kumapeto kwa thupi waukulu, wamphamvu chipsyepsye. Iye anatembenuka mu zikuchepa, kotheka kusamukira ku kumalavula. Pamene nkhanu mabasi nakhala Mwachitsanzo, algae, tidzapeza mbali zonse tinyanga yake yaitali.

chakudya

Nkhanu - ndi omnivore. Menyu, anthu awa m'madzi imakhala zomera ndi algae, ngakhale pansi. Kawirikawiri nambala yaikulu mitundu nkhanu ali pafupi ena maukonde iwo mofulumira umeze nsomba zokodwa kuti, ngati nthawi osazindikira ndiphunzire, asodzi atha kutenga mafupa okhaokha opanda.

chakudya nkhanu ntchito ziwalo kununkhiza ndi kukhudza. Pamene imfa ya tinyanga kapena diso nthawi imeneyi mwina kwambiri kuonjezera. Nyama likugwiritsa ntchito zala za kuyenda miyendo ndi bristles wa zokhudzana m'kamwa - iwo ali tcheru kwambiri.

kubalana

Nkhanu ndi bisexual, koma amuna ndi akazi zopangitsa ziwalo anapanga pa nthawi zosiyanasiyana. Pamene akutha msinkhu munthu woyamba amakhala wamwamuna, ndipo m'chaka chachitatu cha moyo wake adziwonetsa zosiyana, wamkazi. zazikazi kumata mazira awo pa tsitsi la miyendo m'mimba, kenako aswa ana (m'lingaliro lenileni - kuvala ndi inu), mpaka mazira aswa mphutsi kuoneka.

zophikiratu

Ndipo nyama amagwira kale kudyedwa. Maphikidwe kuphika chakudya, nsomba kuphatikizapo deta monga zosakaniza, anthu ambiri mwa anthu, makamaka okhala m'malire. Ngati nsomba zina zambiri, nkhanu awa ali wolemera mu mapuloteni ndi calcium, kuphatikizapo ndekha mu kuchuluka ka zopatsa mphamvu. Zakudya ndi nkhanu - gwero wabwino wa "olondola" mafuta ndi mmene chakudya, ndithudi, ndi chokoma ndi wathanzi chakudya chokoma.
