Ndizodabwitsa kuti kalulu wam'nyanja samawoneka konse ngati kanyama kakang'ono kokhala ndi makutu - ndi chisindikizo chachikulu, chotchedwa chidindo cha ndevu. Nyamayo ndi ya nyama zolusa ndipo, ngakhale ndi yayikulu kwambiri, imakhala yamanyazi komanso yosamala. Nyama yamphongoyo imakopa osaka nyama chifukwa cha khungu lolimba komanso losasunthika, lomwe limagwiritsidwa ntchito popanga nsapato, zingwe, kayaks ndi zinthu zina. Komanso, nyama ndi mafuta a chisindikizo cha ndevu amadyedwa. Kalulu wam'madzi amakhala munyanja ya Arctic ndi Pacific mpaka kukafika ku Tatar Strait.
Kufotokozera kwa chisindikizo cha ndevu
Ma Lakhtaks amachita modabwitsa kwambiri pamtunda - amalumpha ngati hares. Chisindikizo chachikulu chimakhala ndi thupi lalikulu komanso lolimba, lomwe kutalika kwake kumatha kufika 2.5 mita. Pafupifupi, akuluakulu amalemera makilogalamu 220 mpaka 280, koma zisindikizo za ndevu zolemera makilogalamu 360 zakumanananso. Nyama yamphongo ili ndi mutu wozungulira ndi khosi lalifupi kwambiri, zipsepse zazing'ono, zomwe zimayandikira khosi ndikuwongolera kumtunda. Pakamwa pa chisindikizo cha ndevu chalitali. Mbali yapadera ya nyama iyi ndiyowongoka, yolimba komanso vibrissae yayitali.
Kalulu wa m'nyanja amasinthasintha nyengo yovuta chifukwa cha mafuta ake, omwe amatha kupanga 40% yaunyama wonse. Chisindikizo cha ndevu sichikhala ndi underfur, ndipo awn ndi yayifupi komanso yolimba. Nyama zam'madzi ndizofiirira, zomwe zimakhala zowala pafupi ndi mimba. Anthu ena ali ndi mzere wakuda wabuluu wofanana ndi lamba. Pakhoza kukhala mabala oyera pamutu pa zisindikizo zandevu.
Zisindikizo za ndevu zimakhala ndi ziwalo zamkati zokha, motero zimawoneka ngati mabowo pamutu.
Chakudya ndi moyo
Mbalame zam'nyanja ndizodya. Amatha kuyenda pansi pamadzi mosavuta 70-150 m ndikutenga nyama yawo. Lakhtaks amadyetsa ma molluscs ndi crustaceans. Nsomba amathanso kupezeka pachakudya cha chisindikizo, chotchedwa capelin, herring, flounder, Arctic cod, haddock, gerbil ndi cod. M'nyengo yotentha, nyama zimakhala zosusuka kwambiri, chifukwa zimasungira mafuta m'nyengo yozizira. Kupulumuka kwake mtsogolomo kumadalira mafuta osindikizira a chisindikizo cha ndevu.
Amphibian otsogola amakhala ocheperako. Amakonda kukhala m'dera lotukuka ndipo sakonda kusamuka. Nyama zimakonda kukhala pawokha, koma ngakhale wina "atasochera" patsamba lawo, samakonza ndewu ndi ndewu. M'malo mwake, zisindikizo za ndevu ndizabwino komanso zamtendere.
Kuswana chisindikizo cha ndevu
Zisindikizo zakumpoto zitha kukhala zaka 30. Akuluakulu amalumikizana nthawi yokhwima yokha. M'nyengo yotsekemera, anyani amphongo amayamba kuimba, ndipo amveketsa phokoso lalikulu. Mkazi amasankha mnzake potengera luso lake "loimba". Pambuyo pokwatirana, chidindocho chimatha kusunga umuna wa mnzake kwa miyezi iwiri "ndikusankha" mphindi yoyenera ya umuna. Mayi wamkazi amakhala ndi pakati pafupifupi miyezi 9, kenako mwana m'modzi amabadwa.
Chisindikizo cha ndevu zachikazi ndi mwana wake
Hares obadwa kumene obadwa kumene amalemera pafupifupi 30 kg. Amabadwa ndi tsitsi lofewa komanso lofewa ndipo amatha kale kusambira ndikutsika. Mayi wachinyamata amadyetsa ana ake mkaka pafupifupi mwezi umodzi (m'maola 24 mwana amatha kumwa mpaka malita 8). Zitsamba zimakula msanga, koma zazikazi sizimasiyana ndi zimbalangondo zazing'ono zazitali nthawi yayitali.
Kukula msinkhu kwa chisindikizo cha ndevu kumayamba ndi zaka 4-7.
Adani a zisindikizo
Zimbalangondo zakuda ndi zofiirira ndizowopsa ku zisindikizo za ndevu.
Chimbalangondo chofiirira
Chimbalangondo chakumtunda
Kuphatikiza apo, pokhala pachipale chofewa panyanja, zisindikizo za ndevu zili pachiwopsezo chodyedwa ndi anamgumi opha, omwe amathwera pansi ndikugwa kuchokera kumtunda ndi unyinji wawo wonse. Zisindikizo zimayambukiranso ndi helminth infestation, yomwe imayamwa michere yonse ndikupha nyama.
