Common chisindikizo: kuoneka, malo okhala, adani

chisindikizo Common ndi imodzi mwa anthu ochepa a dziko lathuli, zimene amakonda ozizira ofunda. Ndipotu, ndicho chifukwa iwo lingapezeke mu zigawo kutali chipale anaphimba. Chifukwa cha ichi nthawi yaitali, asayansi akhoza kuphunzira nyama bwino. Ndi kokha tsopano kuti patsogolo unapita patsogolo kwambiri tinatsegula iwo moyo wodabwitsa mu chilengedwe.

Mabanga, kapena wamba, chisindikizo: malo

nthumwi zonse chikondi kwa nyengo yozizira. Choncho, pafupifupi onse a zisindikizo zimapezeka m'madera kumadzulo ndi kum'mawa kwa Ocean Arctic. Kuti ndi uthunthu wawo imafika ku Nyanja Bering, Botfortovo ndi Chukchi Pacific. Komanso, angapezeke mu madzi a m'mphepete mwa nyanja Greenland ndi Nyanja Barents.

Pankhani ya Pacific ndi nyanja ya Atlantic, apa mukhoza kupeza oimira mtundu uwu. Apa tikukhala basi m'madera amenewa wa njuchi sizikhala zambiri - mbadwa kunyumba kwa zisindikizo akuti ndi kozizira.

Species mabanga chisindikizo

Pakali pano, chiwerengero cha zisindikizo gombe pafupifupi 500 zikwi. Anthu. nyama zonse ndi zofanana kwambiri ndi mzake, koma pa nthawi yomweyo, asayansi anapeza angapo subspecies wapadera. Mokulira gulu otere akugwirizana malo awo. Komabe, pali kusiyana kunja pakati pa madera osiyanasiyana.

Choncho, chisindikizo wamba lagawidwa ndi subtypes zotsatirazi:

• East Atlantic - ndi ambiri, amakhala pamodzi coastlines a Kumpoto kwa Ulaya ndi Western Asia.
• West Atlantic subspecies - ali pafupifupi buku lonse kum'mawa gawo la North America.
• M'midzi Pacific nyama awa okhala dera la kumadzulo kwa North America.
• Ungava chisindikizo - wapadera woimira mitundu wakonda moyo pamodzi madzi m'malo expanses m'madzi.
• Sindikiza chilumba - amakhala chiwembu kakang'ono ka dziko, anamwazikana mu nyanja pafupi ndi doko la Asia.

maonekedwe

Kodi tikudziwa bwanji zinthu zakunja amene ali ndi chidindo wamba? Photos nyama anapangidwa m'madera onse a kozizira, asiya asayansi yosanthula mitundu yonse wonse. Mfundo chidwi: pafupifupi subspecies onse chisindikizo cha tione wamba ngati achibale mahatchi. The kuchotserapo yekha ndi toyesa Pacific kuti ndi pang'ono kuposa awo kukula anzake thupi.

Koma ku kunja kwa. Mtundu zisindikizo zingasiyane mu moyo wawo. Komabe, ambiri a mtundu ubweya zimasiyanasiyana pakati imvi kapena pabuka-bulauni. Pa nthawi yomweyo padziko thupi nyama m'njira wachisokonezo anamwazikana mawanga mdima. Makamaka, ndi chifukwa cha iwo mtundu nthawi zina amatchedwanso "Umboni Wopereŵera".

Pankhani kukula, pafupifupi chisindikizo wamba akula mamita 1.8. Pankhaniyi, thupi lawo zimasiyanasiyana pakati makilogalamu 150-165. Iwo ayenera kukumbukira kuti akazi ndi nthawi laling'ono kwambiri chiwerengero kuposa amuna.

Makhalidwe ndi malo

chisindikizo Common wakonda kukhazikika pa gombe lamiyala pamodzi madzi m'mphepete mwa nyanja. Pa nthawi yomweyo iye amayesetsa kupewa dziko lotseguka, kuti zikope tcheru cha alendo. Mfundo chidwi n'chakuti, mosiyana ndi achibale awo pafupi, chisindikizo wamba alibe ulendo wawo. Mtundu uwu wa nthaŵi yaitali pamalo amodzi ndi masamba okha pamene kuli koyenera kutero.

Koma zakudya, nyama pankhani imeneyi ndi ogwirira weniweni. Iwo kusaka makamaka madzi, chifukwa chinthu ichi - kwawo. Monga nyama awo kusankha wamng'ono nimble nsomba: capelin, hering'i, duwa m'nyanja zikuluzikulu m'nyanja zikuluzikulu kumalo ozizira ndi zina zotero. Komabe, pamene palibe phindu ngati, zisindikizo mungasangalale yosavuta invertebrates.

kubalana a zisindikizo

Za 5 chaka moyo wa amuna kwa nthawi yoyamba kukondana kwambiri atsikana. Koma zazikazi amakula msanga, iwo ndi kugonana umayamba zaka 3 zakubadwa. Gestation kumatenga miyezi 11. Pankhaniyi, kuwala wabadwa ng'ombe chimodzi chokha, pokha pokha yosowa kwambiri, mkazi akhoza kupanga angapo ana.

Pafupifupi zisindikizo amuna amakhala 25-30 zaka, zomwe ndi zabwinobwino kuti mtundu wawo. "Madona" zinali mwayi, monga zaka zawo pazipita zimasiyanasiyana pakati pa zaka 35-40. Asayansi sangawamvetsetse chikhalidwe cha zodabwitsazi, koma zikutanthauza kuti akugwirizana ndi ntchito wamkazi maliseche.

adani a zisindikizo

Anthu ambiri amakhulupirira kuti mdani chachikulu cha chisindikizo wamba chimbalangondo kumalo ozizira. mawu zimenezi si zoona kwathunthu. Ngakhale kuti toed chilombo kwenikweni amakonda kusaka nyama plump, mu ukapolo kufa chochepa cha nyama.

Ngozi kwambiri ndi wochititsidwa ndi wakupha zinsomba. Izi ogwirira m'madzi m'kuphethira kwa diso aigwire ndi kudya gaping zofunkha. Komanso yekha zisindikizo yachangu akhoza amachoka pa wakupha chinsomba, ndipo kenako, mu nthawi kuthawira gombe.
