Chisindikizo - ndi nyama?

Lero tikhoza kunena motsimikiza kuti ngati chidindo chifukwa chiwerengero cha mavuto aakulu, anaphedwa mu njira ya kusanduka mitundu, ndiye Dziko lapansi likanakhala osauka kwambiri. Chifukwa chiyani? Timayesa kuyankha funso m'nkhani ino.

Atamaliza kuliwerenga, mudzapeza mfundo zimene nyama ndi chidindo, kodi phindu lake, zimene zimaonetsa kuti ali, ndi zina zotero.

zambiri

Common dzina m'madzi nyama mabanja amenewa zisindikizo (Caspian, ringed ndi Baikalian) - chisindikizo.

Nyanja zisindikizo mu Russia adafalitsa Murmansk kwa Bering Strait m'malire, kuphatikizapo mu madzi Franz Josef Land, Novaya Zemlya, Severnaya Zemlya, Nyanja White ndi zilumba Chatsopano Siberia. Iwo amakhala mbali mwa nyanja ya nyanja ya Okhotsk kuphatikizapo kumalo ake ndi madzi m'mphepete mwa nyanja ya Chitata Khwalala, Sakhalin Gulf ndi East Sakhalin. Habitat chisindikizo umalandira gombe la chilumba Japanese wa Hokkaido.

Palinso zisindikizo kuti moyo mu dziwe ndi madzi abwino. Mwachitsanzo, wotchuka Russian Nyanja Baikal imadziwika kulikonse mu dziko osati chifukwa nyanja ofunika wokongola. madzi ake ndi anthu ndi nyama wapadera, zomwe sizipezeka pena paliponse malo ofanana. chosindikizira ichi, ali kuderako ndi relict ya zinyama Ukachenjede. Limatchedwa Baikal chisindikizo.

mafotokozedwe

zisindikizo ndi ndani? Nyama zimenezi chodabwitsa ndi fusiform thupi, mokoma anagubuduza mu mutu wake.

kukula akamafika 165 masentimita ndi kulemera 50 130 makilogalamu. nyama torso lili wambirimbiri subcutaneous mafuta, mwangwiro amasunga kutentha mu madzi ozizira ndi kuthandiza nyama kudikira nyengo yaitali njala, komanso padziko kugwira madzi akagona. Iwo kugona choncho momveka kuti ngakhale nthawi zina zosiyana awo angapatutse popanda kusokoneza tulo tawo.

khungu amphamvu nyama okuta zovuta, wandiweyani ndi waufupi tsitsi odula. Pakati pa zala ali ndi makutu ndi zipsepse kutsogolo zili ndi zikhadabu wamphamvu. Ndi chifukwa cha kutsogolo miyendo zisindikizo kuchita potulukira mu ayezi, kupita pambuyo kusaka ndi kumasuka pa miyala kapena pa ayezi, ndi kupuma mpweya wabwino.

chisindikizo ali ndi mphamvu yapadera kukhala pansi pa madzi kwa mphindi 40. mosalekeza. Ichi ndi chifukwa kukhalapo kwa pang'ono kuwala ndipo zili kusungunuka mpweya magazi. Chifukwa miyendo kunsana nyama amasambira mofulumira ndithu pansi pa madzi, koma padziko izo si zinthu zosamveka ndi kovuta.

Zisindikizo mu Nyanja Baikal

M'mbuyomu, ndi Baikal chisindikizo nyama zinali zomvetsa akulemekezedwa, makamaka pakati pa mitundu, ali kwambiri za kusaka nyanja. Ngakhale tsopano, ena a Orochi m'matumba m'kamwa mwa chisindikizo yotengedwa adyo zakutchire ndi fodya, chifukwa iwo ndi mtundu wa nsembe Tam, kumene chisindikizo zogwirizana kwambiri chifukwa iye ali mwini zinthu m'madzi.

Mu masiku akale, Baikal chisindikizo kusaka inali yofunika kwambiri chuma ndi umoyo m'deralo, ulimi wa nyama ndi mosamalitsa zochepa. Poyerekeza ndi mitundu ina ya apeze zikopa chisindikizo cha ubweya (achinyamata ndi akulu mofanana) ndi yabwino zipangizo ubweya yaiwisi, kotero zichuluka koposa anayamikira.

Habitat Baikal zisindikizo

M'chilimwe (June) pagombe zilumba Ushkaniye akulimbana ndi kuchuluka kwa nyama - chilumbachi kwa iwo momasuka masoka achilengedwe rookery. Dzuwa likulowa, zisindikizo kuyamba kuyenda awo misa ku zilumba.

Pa frosts choopsa cha Siberia nyanja kwathunthu amaundana. Pamaso pa isanayambike ozizira chisindikizo nyengo ntchito mano ndi yoteroyo kutsogolo ndi zikhadabu zakuthwa kukumba kupuma mabowo okha. Kawirikawiri yozizira padziko m'nyanja mazira ambiri a akazi nthawi pakati.

Pa mafakitale

Chisindikizo - nyama muli yambiri mafuta chonyezimila, ali ndi zothandiza mankhwala. Kupanga malonda a zisindikizo lero, ngati mazana zapitazo, kutsatira zolinga zofanana.

Mafuta a nyama ndi anthu ambiri mogwira mtima ntchito mankhwala a matenda ena amagwirizana ndi hypothermia (kutupa, frostbite), ndipo nyama zake ntchito chakudya ndi akusowa vitamini C (monga chiseyeye).

Komabe, zifukwa kupanga zikuluzikulu mafakitale - zikopa chidali nyama. Zipewa ndi zovala kuchokera wandiweyani, wandiweyani ubweya ndi nsalu cholimba ndi ambiri otchuka pakati pa anthu a North, ndi m'madera ambiri kum'mwera.

kubalana

chisindikizo Hatchling, kawirikawiri zikuoneka m'ma March. Pambuyo pa mapeto a yozizira, akazi amakwawa mmadzi kumtunda ayezi ndi kubereka ana. Koma mkazi woyamba kumanga khola mu chisanu kwa ana awo am'tsogolo.

Mwatsoka, nthawi imeneyi ringed chisindikizo ayang'anizana ndi zoopsa kwambiri - kuti sizivuta kuti anthu opha nyama zambiri ndi alenje. Kwenikweni zisindikizo abadwe ngati mwana, koma pangakhale awiri kapena kuposa.

Kubadwa kulemera, zambiri za 4 makilogalamu. Iwo amabadwa ndi wokongola kwambiri zikopa woyera, powapatsa chikondi ndi kubisa yodalirika mu chisanu.

Pambuyo molting chisindikizo Bakuman amapeza ndi ubweya silvery.

moyo amayembekezeka

Growth chisindikizo monga kutalika ndi kulemera, pali nthawi yaitali (zaka 20). Ena nyama ndi kufa "nedorosshimi", monga zaka zawo ambiri anthu ndi wofanana ndi zaka 8-9 yokha. Pali milandu kuti ena zisindikizo moyo mpaka zaka 40-60, koma iwo ali ochepa kwambiri. Pafupifupi theka la anthu onse - wamng'ono chisindikizo za zaka 5 zaka. nyama Akale (zaka 6-16) amapanga mbali yaikulu ya theka lina la zisindikizo.

Chisindikizo - nyama zachilendo m'njira yakuti msinkhu wake, asayansi kudziwa ndi mano kapena zikhadabo, amene inu mukhoza kuwona mphete pachaka, monga amene ali ndi nkhuni.

chakudya

Chifukwa cha zisindikizo m'madzi chakudya - nsomba ndi nkhono, limene aggregations lalikulu mu zigawo ulemu wa madzi.

chakudya ndimaikonda ndi Baikal chisindikizo - ndi Baikal ndi goby nsomba kansomba. Pa chaka, nyama amagwiritsa kuposa tani chakudya nyama. Nthawi zina zifika mu chakudya ndi Cisco pafupifupi 3% ya zakudya zake tsiku.

mfundo zosangalatsa

1. Dlinnomordye ndi doko zisindikizo ndi njovu nyanja kugawana malo omwewo - nyanja.

2. Chisindikizo - ndi diver kwambiri, kukwaniritsa akuya mamita 400.

3. Nthawi zambiri, zisindikizo sitikukhala mu madzi, koma nyanja Baikal mu Russia wakhala kunyumba weniweni ena a m'banjamo. Kodi anthu zisindikizo mu Nyanja Baikal? Padakali, ikhala chinsinsi. Malinga ndi nthano ina, mu malo awa pali ena osadziwika mobisa njira kulumikiza kunyanja nyanja. Asayansi apeza kuti palibe umboni wa mfundo imeneyi. Njira zambiri ndi Baikal chisindikizo pa Angara ndi Yenisei. Iwo ananena kuti pano chimodzimodzi ndi kumumenya nsomba omul.
