Kakang'ono kakang'ono ka possum ndi nyama yodabwitsa, yodziwika kuti ndi yochenjera. Banja la possum lili ndi mabanja awiri, momwe ma subspecies 17 ndiosiyana kwambiri.
Kufotokozera
Nyama izi ndizochepa kukula: kuyambira mainchesi asanu ndi awiri mpaka makumi asanu kutalika. Mchira, monga lamulo, m'ma subspecies onse ndi wamphamvu kwambiri komanso wolimba (kutalika kwa mchira kumasiyana masentimita 4 mpaka 55), omwe amagwiritsanso ntchito nthambi. Kulemera kwa nyamazo kulinso kosiyana kwambiri. Mwachitsanzo, kulemera kwa chisomo chachikulire cha Chacoesian sikupitilira magalamu 40. Achibale otchuka kwambiri omwe amapezeka wamba komanso Virginian amafika pa kilogalamu 6 zolemera.
Ubweya wamtunduwu ndiwotalika komanso wonenepa. Mtundu wa thupi ndi wotuwa, miyendo ndi yakuda, pafupifupi yakuda. Chosompsacho chimatambasulidwa ndipo chili ndi kuwala (pafupifupi koyera).
Chikhalidwe
Malo okhala ma possums ndi otakata kwambiri ndipo amayamba kum'mwera chakum'mawa kwa Canada, kenako kudutsa madera onse akum'mawa (kuchokera ku West Virginia kupita ku Alabama). Opossums afalikiranso ku South America kontinenti: ku Argentina, Peru, Brazil, Uruguay ndi Bolivia. Mitundu ina imapezeka ku Caribbean.
Nyama izi zimakonda kukhazikika m'nkhalango, m'mapiri ndi m'zipululu. Pali mitundu yodziwika yomwe imakhala mpaka 4,000 metres pamwamba pa nyanja.
Kodi possum imadya chiyani?
Oposamu ndi nyama zamtundu uliwonse. Zakudya zawo zimaphatikizapo zipatso (monga mphesa zakutchire kapena maula), mbewu ndi mbewu (monga chimanga kuchokera kumunda). Amatha kudya mbewa zochepa. Abuluzi osiyanasiyana, achule, nkhono, slugs ndi nyongolotsi zimaphatikizidwanso muzakudya zosiyanasiyana. Mbalame zazing'ono zimathanso kupita ku possum kukadya nkhomaliro. Chakudya chokoma kwambiri ndimazira a mbalame. Mtengowu umapeza chisa, kumamatira ndi mchira wake wamphamvu ku nthambi yomwe imakula kwambiri, ikulendewera pansi ndikubera mazira pachisa.
Popeza mitundu yambiri ya opossum imakhala ndi chitetezo chamtundu wina wamankhwala amtundu wa njoka, njoka zimalowanso mchakudyacho, makamaka, mitundu ina imatha kusaka njoka.
Komanso, m'malo omwe mumakhala anthu ambiri, ma possum nthawi zambiri amapeza chakudya chawo kuchokera kumatini azinyalala.
Adani achilengedwe
Possums ali ndi adani okwanira m'malo awo achilengedwe.
Kwa akuluakulu, nkhandwe ndi ziphuphu zimakhala zoopsa. Ma Coyotes amakhalanso osaka ma possum. Mbalame zazikuluzikulu zomwe zimawopsezanso zimawopseza (makamaka akadzidzi).
Njoka ndizoopsa kwambiri kwa achinyamata.
Zosangalatsa
- Mimba yama possum imangokhala milungu ingapo, kapena mpaka masiku 13. Munda womwe mpaka ana 25 amabadwa. Iwo ali akhungu ndi osowa chochita. Ndi amayi, anawo amakhala mpaka miyezi 3 -3.5. Kuyambira ali ndi miyezi iwiri, anawo amayenda kumbuyo kwa amayi, atagwira paubweya.
- Opossum ya ku Virginia imalemera magalamu 0,13 okha pobadwa, ndipo kutalika kwa thupi kumakhala mamilimita 14.
- Amakhulupirira kuti possums ndizo nyama zakale kwambiri padziko lapansi. Ndipo kwa zaka zambiri, chisinthiko sichinasinthe.
- Possums ali ndi njira yachilendo kwambiri yodzitetezera kwa adani. Chilombocho chikamawona kuti chikuwopsezedwa, chimagwera chammbali, ndikufa. Pa nthawi imodzimodziyo, ikatulutsa fungo lonunkhira komanso lonyansa, thovu limatuluka mkamwa, ndipo maso amakhala opaka magalasi, nyama imasiya kupuma. Chifukwa chake possum imakhala kwa kanthawi mpaka chiwopsezo chitadutsa.
