• Njoka ya Dekey (lat.Storeria dekayi) ndi njoka yopanda poizoni yochokera kubanja yosiyana kale. Ili ndi masamba 8. Ili ndi dzina lake polemekeza wolemba zinyama waku America James Decay (1792-1851).

Kutalika konseku kumafika masentimita 23 mpaka 33. Mutuwu ndi wocheperako. Thupi ndi lalitali komanso lochepera. Mtundu wa msana ndi wa bulauni kapena wonyezimira; Mimba yake ndi yapinki.

Zimapezeka m'matupi amadzi, m'malo otentha, kupewa malo owuma. Imapezeka m'midzi yambiri ngakhale m'mizinda yayikulu. Yogwira ntchito usiku, masana imasungidwa pansi pa mwala wosalala, masamba ogwa, ogona njanji ndi zinthu zina zitagona pansi. Amadyetsa nyama za padziko lapansi, tizilombo, ma millile, ma mollus, nkhono, komanso ma amphibians ang'onoang'ono.

Uwu ndi njoka yopuma. Yaikazi imabereka ana 14 aamuna.

Amakhala kum'mwera chakum'mawa kwa Canada, kudutsa kum'mawa kwa USA mpaka kumpoto chakum'mawa kwa Mexico. Imapezeka ku Honduras, Guatemala ndi Belize.

Ngwazi

Ng'ona yaying'ono kwambiri padziko lapansi imadziwika kuti ndi ng'ona yoluka.

Kukula kwa ng'ona yakale yolusa nthawi zambiri sikufika kupitirira 1.5 m, kutalika kwakukulu kojambulidwa ndi 1.9 m. Utoto ndi wakuda, wachikasu pamimba ndi mawanga akuda. Mwa achichepere, monga lamulo, pamakhala mikwingwirima ya bulauni kumbuyo ndi m'mbali ndi mawanga achikaso pamutu. Chifukwa cha kukula kwake kocheperako, nyanjayi ili pachiwopsezo chowonjezereka kuchokera kwa adani, chifukwa imakhala ndi mbali zoyenda bwino, khosi ndi mchira poyerekeza ndi ming'alu ina.

Ziphuphu

Pomwe chifuwa cha zotungira - buluzi wamkulu kwambiri, wam'ng'ono kwambiri pakati pawo amatha kutchedwa checko chakumaso. Mitundu yazotengera zazing'onozi ndizophatikizira: South, North America, Islands Islands.

Kutalika kwa amuna a nkhungu yozungulira-kuzungulira sikupitirira 16 mm, akazi - 18 mm (1.6-1.8 cm). Izi zapamwamba zimalemera pafupifupi 0,15-0.2 - magalamu.

Pterosaurs

Gulu la akatswiri ofufuza za zinthu zakale ochokera ku Yunivesite ya Southampton adaphunzira mafupa a nyama yoyambirira yomwe idapezedwa mu 2009 pachilumba cha Canada ku Hornby ndipo adazindikira kuti anali a pterosaur yaying'ono yomwe idakhala zaka pafupifupi mamiliyoni 77 zapitazo, kumapeto kwa Cretaceous.

Asayansi azindikira kuti kukula kwa mtundu watsopano Nemicolopterus cryptics linali laling'ono kuposa mphaka, ndipo mapiko ake sanali oposa 40 cm.

Zosadabwitsa, koma pakati pa abale Nemicolopterus panali ma pterosaurs akuluakulu kwambiri, monga quetzalcoatlAkhoza kukhala ukulu wa ndege.

Kufotokozera kwa mawonekedwe a serpenti Kubowola.

Njoka yofiirirayo ndi nyama yaing'ono kwambiri yomwe siimapitilira 15 inches. Kukula kwa thupi kuyambira 23.0 mpaka 52.7 cm, zazikazi ndizokulirapo. Torso yokhala ndi maso akulu komanso masikelo olimba. Mtundu wa integument nthawi zambiri umakhala wonyezimira wamtambo wokhala ndi maso opepuka kumbuyo, omwe umakhota kumbali ndi madontho akuda. Mimba yake ndi yoyera. Pakati pazere ndi mizere 17 yamiyeso. Chishango chothandizira chimagawidwa.

Kuwola kwa Njoka (Storeria dekayi)

Wamphongo ndi wamkazi amawoneka chimodzimodzi, koma yamphongo imakhala ndi mchira wautali. Pali mitundu ingapo ya Storeria dekayi yomwe imawoneka yosiyana pang'ono, koma palibe umboni wosalemba wa kusintha kwamtundu uliwonse wamitundu. Njoka zazing'onoting'ono zazing'ono ndizochepa kwambiri, mainchesi 1-2 okha. Anthu pawokha amapakidwa zakuda kapena zakuda. Mbali yodziwika bwino ya njoka zazing'ono ndi mphete zofiirira zoyera. Pakadali pano, mamba olemekezeka amasiyana ndi mitundu ina.

Kufalikira kwa njoka Kuwonongeka.

Njoka zowola zili ponseponse ku North America. Mtunduwu umapezeka ku South Maine, Southern Quebec, Southern Ontario, Michigan, Minnesota ndi kumpoto chakum'mawa kwa South Dakota, ku South Florida. Amakhala m'mphepete mwa Gulf of Mexico, Kum'mawa ndi Kumwera kwa Mexico ku Veracruz ndi Oaxaca ndi Chiapas ku Honduras. Kumakhala kumwera kwa Canada. Kugawidwa ku United States kummawa kwa Rocky Mountain komanso kumpoto kwa Mexico.

Kukhazikika kwa njoka Kuwonongeka.

Njoka zowola ndi mitundu yambiri m'malo awo. Cholinga chake ndikuti mitundu yonseyi ndi yazing'ono kwambiri ndipo imakonda mitundu yosiyanasiyana ya mitundu. Amapezeka pafupifupi mitundu yonse ya padziko lapansi komanso yozungulira yomwe ili m'malo awo, kuphatikiza m'mizinda. Amakhala m'nkhalango zotentha. Nthawi zambiri amakhala m'malo opanda chinyezi, koma sakhala amtundu womwe amatsatira matupi amadzi.

Kudzola Njoka - North America

Njoka zowola zimakonda kupezeka pakati pa zinyalala, pakati pa malo okhala madzi ku Florida, pansi panthaka kapena nyumba. Njoka zofiirira nthawi zambiri zimabisala pakati pa miyala kuthengo komanso m'mizinda yayikulu. Njoka izi zimakhala moyo wawo wonse mobisalira, koma nthawi yamvula yambiri nthawi zina zimapita kunja. Nthawi zambiri izi zimachitika mu Okutobala - Novembala komanso kumapeto kwa Marichi - Epulo, pomwe zibwezizo zimasunthira hibernation. Nthawi zina, kuwola kumakhala njoka hibernate pamodzi ndi mitundu ina, njoka yofiira komanso njoka yobiriwira yosalala.

Kubalanso njoka Kuwonongeka.

Njoka za Dekey ndizotengera zamtundu. Mitundu yamoyo iyi, mazirawo amakula mthupi la mayi. Yaikaziyo imabereka ana aang'ono 12 mpaka 20 a njoka. Izi zimachitika theka lachiwiri la chilimwe mozungulira July - kumayambiriro kwa Ogasiti. Anthu obadwa kumene samalandira chisamaliro chilichonse cha makolo kuchokera kwa akulu ndipo amangosiyidwa okha. Koma nthawi zina njoka zazing'ono zofiirira zimakhala pafupi ndi makolo awo kwakanthawi.

Njoka zazing'ono zofiirira zimatha kutha kumapeto kwa chilimwe chachiwiri, nthawi zambiri pofika nthawi imeneyi thupi lawo limafupika.

Zochepa sizikudziwika za kutalika kwa njoka zakutchire, koma m'ndende, anthu ena amakhalabe ndi zaka 7. Mwina nthawi yomweyo amakhala m'malo achilengedwe, koma njoka za Dekhey zili ndi adani ochulukirapo, motero gawo lokhalo la mbewu limakula.

Kuwola kwa Njoka (Storeria dekayi) - Mawonekedwe

Zokhudza machitidwe a njoka.

Panthawi yobereketsa, njoka za Dekey zimapezana kumapazi a pheromones zomwe zinsinsi zachikazi zimadziwana. Mwa fungo, champhongo chimazindikira kukhalapo kwa mnzake. Kunja kwa nyengo yakubereka, zokwawa zimakhala zayekha.

Njoka zofiirira zimalumikizana wina ndi mnzake makamaka kudzera pakukhudza komanso kununkhira. Amagwiritsa ntchito malilime omwe ali ndi ana kuti atenge mankhwala ochokera kumlengalenga, ndipo chida china chapamwamba chimasankha izi. Chifukwa chake, njoka zofiirira zimakhala makamaka mobisa ndipo usiku, zimangogwiritsa ntchito kununkhira kwawo kuti zipeze nyama. Mtundu wamtunduwu umakonda zonyezimira ndipo umakhala ndi masomphenya abwino. Njoka zofiirira nthawi zambiri zimagwidwa ndi achule akuluakulu ndi mikanda, njoka zikuluzikulu, akhwangwala, akambuku, zibangiri, mitundu ina ya mbalame, ziweto ndi zoluka.

Njoka ya Dekey (Storeria dekayi), yotchedwa njoka ya bulauni

Njoka za Decay zikaoneka kuti zikuwopseza, zimasyasira matupi awo kuti zizikulirapo, zikhale zaukali, komanso zimatulutsa madzi onunkhira osafunikira.

Makhalidwe otetezedwa ndi njoka.

Njoka yowola imayimiriridwa ndi anthu ambiri omwe amapanga zochulukitsa. Chiwerengero chonse cha nyama zazikuluzikuluzi sizikudziwika, koma mosakayikira ndizoposa 100,000. Mtundu uwu wa njoka umagawidwa kwanuko (mpaka mahekala mazana) m'malo ambiri. Kugawa, dera lomwe amakhala, kuchuluka kwa magawo, ndipo anthu ali osasunthika.

Zizindikiro izi zimapangitsa kuti njoka ikhale ya Dekey, omwe chikhalidwe chake sichimabweretsa nkhawa. Pakadali pano, kuchuluka kwa zokwawa sikuyenera kutsika mwachangu kuti njoka za Dekei zitha kunena kuti zikuphatikizidwe m'gulu lalikulu kwambiri. Palibe chowopseza kwambiri pamtunduwu. Koma, monga mitundu yonse yodziwika bwino, njoka ya Decay imakhudzidwa ndi kuipitsidwa ndi chiwonongeko cha malo akumidzi ndi matauni. Sizikudziwika kuti akuchitapo chiyani pofuna kuonetsetsa kuti njoka za bulauni zisintha. Mtundu wamtunduwu wa njoka umalekerera kuwonongeka kwakuchulukirapo, koma zomwe zimatsata mtsogolo, zimangolingalira.
