Western pig-nosed nyoka (Heterodon nasicus)

Ndakasangana naHeterodon nasicus anenge makore gumi apfuura. Uye, kutaura chokwadi, ndakatora izvi zvinokambaira kune zvine chepfu: hazvingotaridzi chete sevamwe vavo vane chepfu, asi zvakare vanonyatsotevedzera maitiro eiyo nyoka dzine uturu. Vakafambisa "accordion" kana "caterpillar", senyoka, pavanenge vachiedza kusvika kwavari, vakaita kurwisa kwakasimba nemhere yakasimba uye nechitarisiko chavo chose vakaedza kubata kutya kunotyisa. Ndakashamiswa zvikuru pandakaona kuti idzi "nyoka dzisina uturu", kana kuti, nyoka dzekumadokero dzenguruve (Heterodon nasicus). Ipapo nyoka idzi dzaidhura zvakanyanya uye dzainetsa kuwana kune munhu asina ruzivo nezve terrariumist. Makore akapfuura, uye muzhizha ra10, zviviri zveizvi zvisikwa zvinoyevedza zvakauya kumuunganidzwa wangu. Kwemakore matatu ndakaunganidza ruzivo rwakati kuti mukuchengeta uye kupfuya izvi zvinokambaira zvinoshamisa.

General mashoko

Ngatitangei muhurongwa. Iyo nyoka yekumadokero yenguruve (Heterodon nasicus) inofungidzirwa kuva yakareba mita, kunyange zvazvo vakadzi kazhinji havapfuuri 60-80 cm, uye varume vakatonyanya kuduku, kusvika 25-45 cm. Idzi inyoka diki, "dense" ine muromo wakanyatso pinduka wemhino, wakafanana nemhuno yenguruve (naizvozvo zita). Zviyero zvine keeled zvakasimba, izvo zvinoita kuti muviri wenyoka utaridzike. Nyoka haina chepfu, kunyangwe iine mazino ekumashure, asi, sekutsvagurudza kwakaitwa nemasaenzi eAmerica, hapana migero uye nzira dzechepfu mumazino aya. Nyoka dzerudzi urwu hadzina huturu hwehuturu kana mate ane muchetura anowanikwa mune mamwe marudzi erudzi urwu - Heterodon platyrhinos uye Heterodon simus. Mazino ekumashure anoshanda chete kubaya mhuka uye "kudhawunirodha" mhepo nemvura kubva kumatatya uye matatya paanomedzwa. Nyoka idzi dzinowanzopendwa nemavara egrey, jecha kana kuti akajeka, aine mavara ebrown, tsvuku kana maorivhi kumusana.

Iyo yenguruve-nemhino Heterodon n. nasicus

Areal

Hognose yekumadokero inowanikwa kumaodzanyemba kweCanada uye mazhinji eUnited States, kubva kumaodzanyemba kwakadziva kumabvazuva kweArizona kusvika kumabvazuva kweTexas. Miganhu yekumaodzanyemba kweiyo nhanho hainyanyi kuzivikanwa, sezvo data yeMexico iri zvidimbu. Zvinozivikanwa kuti muganho wekumaodzanyemba wenzvimbo inomhanya kumaodzanyemba kweSan Luis Potosi kumabvazuva uye Durango kumadokero. Zvitatu zvipenyu zvinotsanangurwa kuyambuka: Heterodon nasicus nasicus, H. n. kennerlyi uye H. n. gloydi. Mukufamba kwayo kwese, nyoka yacho haiwanzoitiki, nekuda kwekuderedzwa kwekugara kwechisikigo uye mararamiro epachivande. Yakachengetedzwa neUS Conservation Services.

H. nasicus inogara pane ivhu rakaoma rejecha, asi rinowanikwawo musango pasi. Nyoka inotungamirira mararamiro ekuchera, kuchera. Nheyo yezvokudya ndeye matatya nematatya, makonzo maduku, zvipuka zviduku. Mhosva dzekudya turtle mazai nenguruve-nosed nyoka dzakanyorwa. Kana paine njodzi, inogona kunyepedzera kunge yakafa, ichiburitsa kunhuhwirira kusingafadzi, kunyangwe ini ndisina kuona maitiro akadaro mu terrarium. Nyoka ine oviparous, mukukandira mazai 6-30. Izvo zvinonzi subspecies Heterodon nasicus nasicus inosiyaniswa kubva kune mamwe madiki enyoka-nosed nyoka nedumbu rayo dema.

Zviri mu terrarium

Nekuchengeta nyoka dzine mhuno yenguruve muusungwa, diki terrarium inoyera 50 x 35 cm, yakatwasuka mhando, yakakwana. Kureba hakuna basa, nekuti. nyoka dzinorarama upenyu hwepanyika. Pane imwe mugumo we terrarium, kupisa kwepasi uye kwepamusoro kunoiswa. Kupisa kwepamusoro kunodzimwa usiku. Mu terrarium, zvakakosha kuisa matumba akawanda, mune imwe iyo inogadzira kamuri yakanyorova. Chengetedza avhareji humidity ye50-60%. Tembiricha yakajairika yezviri mukati ndeye 24-26 ° C masikati uye 22-23 ° C usiku. Munzvimbo yekudziya kwenzvimbo, tembiricha inofanira kunge iri 30-32 ° C.

Ivhu riri mu terrarium rinofanira kunge rakasununguka, nokuti. nyoka dzine mhuno yenguruve dzinoichera nemuromo wemuromo wadzo. Ini ndinoshandisa shavings hombe sekutanga, asi yakanyanya kushongedza (yekuchengeta mune yekuratidzwa terrarium) kushandisa yakachekwa hardwood bark (inopihwa kumusika weRussia nevakawanda vanozivikanwa vanogadzira) kana akakosha emhando yekutanga yekuchengeta nyoka dzehumambo. Zvinokurudzirwa kuchengeta nyoka-nosed nyoka imwe neimwe, nokuti. nyaya dzekudya nyama dzevanhu dzakarekodhwa, uye kudyara pamwe chete pakusangana, panguva yekuberekesa. Zvinokambaira zvinokambaira kazhinji zuva nezuva.

Kudyisa

Nyoka dzakatapwa dzinodya kamwechete pamazuva 7-14. Sechikafu mumamiriro emu terrarium, ndinoshandisa huswa huri pakati nepakati nematatya, vana vasina kupfeka makonzo uye mbeva. Zvakakosha kuziva kuti nyoka dzine mhuno yenguruve dzine mudumbu mupfupi, saka zviri nani kushandisa chinhu chimwe chete chepakati nepakati pakudyisa. Kudyisa kunotungamirira kukudzoka, kuramba kwezvokudya uye kuvhiringidzika kwepamuviri. Chikafu chakanakisa chenyoka dzemhuno yenguruve idatya. Kunyangwe kana matambudziko ekugaya atanga, pakudyisa matatya, zvese zvinodzokera kune zvakajairika. Kubva pakudya nguva dzose nemakonzo, kunyange mhuka dzine utano dzine zvigaro zvakasununguka nezvidimbu zvisina kuvharwa zveganda (izvo, zvisinei, hazvisi chiratidzo chechirwere). Kuti zvive nani kudyiwa kwemakonzo asina kupfeka uye makonzo pups nenyoka, tinopa zvinhu zvekudya zvakabvarurwa kana ganda, pasina ganda. Nyoka dzevakuru dzinodya zvakakwana zvinhu zvekudya zvakanyungudutswa.

Shanduko yeganda (molting) munyoka-nemhuno yenguruve inoitika nenzira imwecheteyo sezviri mune zvese zvinokambaira pasi. Chiratidzo chekutanga kwekunyunguduka kuvharika kweganda remuviri nemeso. Panguva ino uye kusvika pakuguma kwe molt, zviri nani kuti usadyisa nyoka. Kazhinji ivo pachavo vanoramba kudya. Mune nyoka-nosed nyoka, kuwanda kwekunyunguduka kunonyanya kuderera kupfuura kune dzimwe mhuka dzinokambaira (muvanhu vakuru - 2 kanomwe pagore, mudiki - zvishoma kakawanda).
