Makupalat (lat.) - banja la njoka. M'mbuyomu ankawaganizira kuti ndi banja lachibale lokhalokha.
Kufotokozera
Kutalika konse kwa oimira banja lino kuchokera pa 50cm mpaka 1mamutu. Mutu ndiwosalala, wamtali. Thupi limakhala lolimba komanso lonyowa, mchirawo umakhala wautali.
Monga njoka zowuma, mphuno imasunthika kumtunda kwa muzzle, maso amawongolera m'mwamba, ndipo mkamwa ndi mphuno zimakhala ndi valavu yapadera yomwe imalepheretsa madzi kuyenda. Komabe, mamba omwe amaphimba thupi sanasinthe kwambiri poyerekeza ndi njoka zam'munda. Mano a chitseko cham'mbuyo cha nsagwada yam'mwamba amakulitsidwa, ali ndi poyambira kutsogolo ndipo amalumikizana ndi kutulutsa kwa poyizoni.
Mtundu wa khungu umakhala wachikasu mpaka bulauni.
Moyo
Mitundu yambiri imakhala m'madzi. Madzi onsewa amakhala opanda madzi komanso madzi abwino, kuphatikizapo ang'onoang'ono, ngakhale osakhalitsa. Mitundu ina ndiyambiri, mwachitsanzo, m'minda ya mpunga ndi m'madambo. Kumbani mabowo. Nthawi zambiri amatuluka pamadzi kupita kumtunda, kumene amakhala ndi chidaliro.
Kuluma kwa njoka'zi kumawumitsa kapena kupha nsomba, crustaceans ndi amphibians, zomwe amadya, koma sizabwino kwa anthu. Njoka izi zimatha kumeza umunthu wawo ngakhale pansi pa madzi.
Habitat
Madzi amakhala kale pamtunda waukulu, wopanga danga kuchokera ku Central ndi Southern Europe mpaka Western China ndi Northwest India. Zimapezeka m'mphepete mwa Nyanja Yakuda ku Russia ndi Ukraine, ku Crimea, Ciscaucasia ndi Transcaucasia, Central Asia ndi Kazakhstan.
Malo okondweretsa njoka zam'madzi ndi malo pafupi ndi matupi amadzi (atsopano ndi mchere). Zimapezeka pafupi ndi mitsinje ndi nyanja, m'mphepete mwa nyanja ndi zilumba zomwe zili munyanja. Zitha kuonedwa pafupi ndi ngalande zothirira m'midzi, paminda yothiriridwa, pamalo opendekera okhala ndi mabango ndi mitsinje yamapiri yowonekera.
Amakonda makamaka malo omwe mabanki ndi pansi adakutidwa ndi miyala yayikulu, ndipo tchire ndi mitengo zimamera m'mphepete mwa nyanja. Yesani kupewa magawo otseguka ndi otsetsereka pafupi ndi madzi.
Machitidwe a njoka yamadzi
Njoka izi zimagwira ntchito masana. M'mawa, amatuluka m'madzimo ndikukasamba padzuwa nthawi yayitali, ndikubisala usiku. M'nyengo yotentha, nthawi yambiri masanawa amakhala m'madzi, ndipo nthawi yamadzulo amapita kumtunda komwe amagona.
Njoka zamadzi zimasambira zonse pamadzi ndi pansi pa madzi. Atatulutsa chisa pamwamba pamadzi, akumwetulira thupi, monga kukwawa, amasambira mwachangu. Kuthawa kuzunzidwa, amabisala ngakhale m'mitsinje ndi mphamvu yamphamvu, pansi pamiyala pansi pamtunda wamtunda wa 2-3 mamita kuchokera kumtunda. Kuwonekera pakatha mphindi 4-5.
M'chilimwe, amakhala malo otetezedwa pansi pazidutswa zamiyala, milu yamitanda yamitengo, tchire lodzala ndi magombe amadzi, ndi zina zambiri.
Njoka zam'madzi nthawi zambiri zimatsata masamba awo ndipo sizipanga timagulu tambiri. Amasamukira mkati mwa 200-400 m.
Amadziwika ndi masomphenya akuthwa kwambiri. Poona munthu ngakhale mita 10, amathamangira kukabisala m'madzi.
Zakudya Zabwino Komanso Kusaka
Njoka zamadzi zimadya kwambiri nsomba, komanso zochepa - amphibians. Amasaka kwambiri komanso kugwira nsomba, kuziyang'ana pansi. Ngati nsomba isambira ku njoka yosagwedezeka, imagwira nyama ndi mphamvu imodzi, koma ikaphonya, siyiyisunga posambira.
Malinga ndi zomwe wapezeka m'madzi muja, njoka zimameza nsomba zazing'ono zomwe pansi pano. Nthawi zambiri nyama zazikulu zimadyedwa pagombe. Kugwira nsomba nthawi zambiri ndi mchira, njokayo imathamangira kumtunda ndipo, ikagwira mwala ndi thupi, kuyesera kuutulutsa mu madzi.
Zisanu
M'nyengo yozizira, njoka zam'madzi zimasowa nthawi yomweyo monga wamba mu Okutobala-Novembala, pomwe zipatsozi zimachitika. Nthawi zambiri mu Seputembala amakhala osagwira ntchito, amabisalira m'maenje, pansi pamiyala yamiyala, pansi pa maziko a nyumba.
Amakonda kubisala m'magulu (nthawi zina mpaka anthu 200) kapena mwayokha. Amatha kukhala yozizira limodzi ndi njoka wamba. Malo omwewo nthawi yozizira (malo owuma pansi pa miyala, ma skigs, burrows) amagwiritsa ntchito njoka zaka zingapo motsatizana.
Kudzuka kumapeto kwa Marichi kapena mu Epulo, kutengera malo, nyengo ndi nyengo yamasika. Amabwera pamtunda pomwe kutentha kwa mpweya kumakwera mpaka kutentha kwa 9-10 ° C, komabe, poyamba sizigwira ntchito. Pobwerera kuzizira, amabisanso m'malo awo okhala.
Kuswana
Nyengo yakukhwima imayamba mu Epulo - koyambirira kwa Meyi, ndipo kuyikira mazira kumachitika kumapeto kwa Juni - mu Julayi. Mu clutch nthawi zambiri mumakhala mazira 6 mpaka 18. Kuyika kwa mkazi aliyense kumatenga maola angapo. M'mazira owala bwino, mazira amawoneka bwino, omwe amayamba kukula ngakhale mthupi la mkazi.
Mazira amadzazidwa masiku 40-50. Njoka zazing'ono ndizogwira, zachangu mwachangu ndipo mawonekedwe ake sizimasiyana ndi maonekedwe akuluakulu, kupatula kukula. Kutalika kwa matupi awo ndi 16-19 cm.
Adani
Njoka zamadzi zomwe zimapezeka m'madziwe nthawi zambiri zimasesedwa ndi anthu, kuwayesa ngati poyizoni kapena tizirombo.
Mwa nyama, adani a njoka zamtunduwu ndi njoka ya chiwombankhanga, ndipo nthawi zina mbalame zina zakudya. Mwachitsanzo, amadziwika kuti kite wakuda amadya njoka zam'madzi ku Caucasus. Zitsamba ndizowopsa kwa iwo. Kwa anthu ang'onoang'ono, seagull ndi nsomba zolusa zitha kukhala zowopsa. Nthawi zina amakodwa ndi nkhandwe ndi mimbulu.
Chiyambidwe cha mafotokozedwe ndi kufotokoza
Chithunzi: Madzi kale
Pomwepo njoka yamadzi ndi njoka yopanda poizoni ya banja kale komanso mtundu wa njoka zenizeni. Zowawa nthawi zambiri zimakhala zolakwika kuti zikhale ndi njoka yoopsa, chifukwa chake, nthawi zina, zimachita nawo nkhanza. Choyamba, mtundu wake umasiyana ndi njoka yamadzi wamba, chifukwa chake ndikulakwitsa kuti njoka yapoizoni.
Kanema: Madzi kale
Njoka yamadzi ilibe maonekedwe achikasu kapena malalanje pamutu pa occipital pamutu, ngati wachibale wamba, wamtundu wina wamtundu wake:
Chochititsa chidwi: Pakati pa njoka zam'madzi pali zotulutsa, zimakhala utoto kwathunthu.
Njoka yamadzi kuchokera kwa wamba imasiyanitsidwa ndi mawonekedwe wozungulira, thupi lake limakutidwa ndi kiyubiki. Ndizosadabwitsa kuti dzina lake lachi Latin "tessellata" potanthauzira limatanthawuza "yokutidwa ndi cubes" kapena "chess". Chifukwa chachilendo ichi, anthu adatcha "chess njer". Ambiri, inde, amaganiza kuti uwu ndi mtundu wa njoka.
Madzi kale osati wachibale yekha wamba, komanso mnansi wake, chifukwa nthawi zambiri amakhala pafupi, malo okhala oyandikana ndi malo omwewo ndi nyengo. Chofunikira kwambiri pamoyo wake wopambana ndi woyenera kupezeka kukhalapo kwamtsinje wamadzi, kuthamanga ndi madzi oyima.
Kuwoneka m'malo opumula akusamba, munthu wotere nthawi zambiri amabweretsa mantha komanso chisokonezo, kwinaku akuvutika. Mantha onsewa komanso mdani wamadzi wakuthengo chifukwa cha umbuli wa anthu, ndizopweteketsa konse komanso ayi.
Maonekedwe ndi mawonekedwe ake
Chithunzi: Madzi a Njoka
Kuphatikiza apo madzi samapatsidwa mawanga owala a lalanje kumbuyo kwake, amakhalanso ndizinthu zina zakunja mwanjira imeneyi. Kutalika kwa thupi la njoka yamadzi kumatha kufika mita imodzi ndi theka, koma anthu kutalika pafupifupi 80 cm nthawi zambiri amapezeka. Akazi ndi okulirapo pang'ono komanso kutalika kuposa amuna. Kutalika kwa njoka wamba kuli ofanana; kumatha kukula kwambiri masentimita angapo.
Poyerekeza ndi njoka wamba, m'mphepete mwa muzzle mumalozedwa kwambiri pamadzi. Monga taonera kale, nthawi zambiri amalakwitsa chifukwa cha njoka chifukwa cha mtundu wake, khungu, komanso kusowa kwa malalanje. Komabe, ngati tingaphunzire za njoka yamadzi mwatsatanetsatane, titha kuona zizindikilo zina zomwe zimasiyanitsa ndi zodontha:
- Mutu wa njoka umakhala wofanana ndi utatu, ndipo njokayo imasalala,
- Zidutswa za njoka ndizazikulu, zam'mimba zazing'ono kwambiri,
- mukayang'ana m'maso mwa njokayo, mutha kuwona kuti mwana wa njokayo wakhazikika, pomwe njokayo yazungulira,
- malinga ndi kukula kwake, chowonjezeracho ndi chaching'ono kuposa njoka, kutalika kwake, monga lamulo, sichidutsa 73 cm, ndipo kutalika kwa njoka kumadutsa mita.
Mamba omwe amaphimba kumtunda kwa zodzikongoletsera ali ndi mawonekedwe okhala ndi nthiti, ndipo nthiti zimapezeka kwakanthawi. Tidazindikira mtundu wa kumbuyo kwa njokayo, ndipo m'mimba mwake mumakhala ofiira amuna ndi amtundu wachikasu amtundu wachikazi. Kumbali yamkati, kumbuyo kwenikweni kumachepetsedwa ndi mawanga amdima omwe amapezeka paliponse pa thupi la njoka.
Chinthu chinanso cha njoka yamadzi ndi malo omwe ali pamalo a occipital a mutu mu mawonekedwe a zilembo "V", nsonga yake imatsogozedwa kutsogolo. Mtundu wa nyama zazing'ono zamadzulo ndizofanana ndi mtundu wa okhwima, mimba zawo zimakhala zoyera. Maso a njoka ali ndi ana ozungulira ndi iris wachikasu wokhala ndi madontho otuwa.
Kodi madzi amakhala kuti?
Gawoli la njoka yamadzi ndilambiri. Poyerekeza ndi mgonero wamba, njokayo imatha kuganiziridwa ngati Thermophilic komanso kumwera. Anakhala kudera lakumwera kwa Europe, ndikukhala kumwera kwa Ukraine ndi Russia, atasankha madera a Don, Kuban, Volga, madera a Azov ndi Black Seas.
Ngati tifotokozere za malire akukhazikika kwa njoka wamba, chithunzicho chikuwoneka motere:
- kumadzulo, mtunduwo umakhala kum'mwera chakumadzulo kwa France (chigwa cha Rhine),
- kum'mwera, malire amayenda kudera lakumpoto kwa Africa, mpaka Pakistan ndi Persian Gulf,
- kutsogolo komwe kumakhala njoka kumadutsa kumpoto chakumadzulo kwa China,
- malire a kumpoto kwa masanjidwewo akufalikira pachitunda cha Volga-Kama.
Kuchokera ku dzina lokhalo lachiwonetsero ndizodziwikiratu kuti sungakhale kutali ndi matupi amadzi, imafunikira magwero amadzi m'malo ake. Mwakutero, mumadzi amadzimadzi amagwiritsa ntchito mkango nthawi yake. Madzi amakonda kukhala m'mbali mwa nyanja, mtsinje, dziwe, nyanja. Ngalande zopangidwa mwaluso ndi zotetezeka zimatha kukhalamo. Anthu akunyanja amakonda kwambiri madzi osayenda kapena aulesi, koma amakhalanso m'mitsinje yozizira, yamkuntho. M'mapiri, njoka yamadzi imatha kukumana pamtunda wamakilomita atatu.
Nthawi zambiri, njoka zimasankha mayiwe okhala ndi khomo lolowera kumadzi kuti azikhalamo, malo otsetsereka omwe amaphimbidwa ndi miyala, dothi kapena mchenga. Mimvi imapewera m'mphepete mwa mapiri. Matupi oyipitsidwa ndi njoka amadutsanso ndi njoka, chifukwa zimasaka ndikudya nyama yaying'ono popanda kukwawa kuchokera m'madzi. Malo okondedwa kwambiri pomwe zirombo zopumulirako zimakonda kupuma komanso kupumula ndi miyala ikuluikulu, yosalala yozungulira yomwe ili m'mphepete mwa mitsinje, kapena nthambi zamitengo, zomwe zimayikidwa mwachindunji pamwamba pamadzi. Njoka zake ndizoyang'ana bwino ndikuyenda korona wamitengo, chifukwa chake zimakonda kukwera nthambi za mbewu zomwe zili pafupi ndi posungira.
Kodi chimadya madzi ndi chiyani?
Chithunzi: Madzi omwe adachokera kale ku Buku Lofiira
Sizosadabwitsa konse kuti mndandanda wamakedzedwe amapangidwa makamaka ndi mbale zam'madzi. Amasaka akudya ake omwe amawakonda, onse mumchere komanso m'madzi atsopano.
Zakudya za nsomba zimakhala:
Amamwa nsomba yaying'ono yomwe ili mgulu la madzi, ndipo amayenera kupumira m'madzi ndi yayikulu, motero amachita nayo gombe.
Chosangalatsa: Pa kusaka kamodzi kopambana, amatha kale kumeza nsomba zazing'ono ndi mainchesi atatu, koma nsomba ndizokulirapo (kutalika kwa 15 cm) zopezeka muzakudya zake.
Kuphatikiza pa nsomba, madziwo samasiyananso kudya achule, ma tadpoles, maads, newts. M'mphepete mwa Nyanja ya Azov ndi Crimea, mumalowa ng'ombe zazing'ombe zambiri, choncho mbadwa zawo amazitcha "ng'ombe yamphongo." Njoka zam'madzi zimakonda kusaka m'njira ziwiri: zimatha kubisala ndikudikirira wobisalira, kenako ndikuyigwira ndi liwiro, kapena ikulondola zomwe zingagwire, mochenjera mochenjera.
Ngati wovulalayo akwanitsa kuthawa nthawi ya nkhondoyi, samupeza, apeza chinthu chatsopano chosakira. Nthawi zambiri, nyama yam'madziyo imamatira pakati penipeni pa nsomba, nyama yayikulu imamangidwa ndi nsagwada zake ndikusambira nayo kumtunda, ndikuyigwira pamwamba pamadzi. Ikakamiza mchira wake pachitsamba china cham'mbali, imakoka katundu wayo kumtunda.
Chakudyacho chimayamba ndi kumeza mutu wa nsomba. Mizere ya nyama ya nyama imatha kukhala yayikulupo kuposa chakudya cham'mutu, chifukwa chake chokwawa chimametsa mothandizidwa ndi mafinya a nsagwada yapansi ndi mafupa omwe amakhala pafupi. Poona izi, zikuwoneka kuti akukwiyira wom'gwirayo.
Chosangalatsa: Ndizodziwika bwino kuti m'mimba mwa imodzi ya njoka mumapezeka njoka zazing'ono wamba.
Mawonekedwe a machitidwe ndi moyo wawo
Chithunzi: Madzi kale
Njoka zam'madzi ndizomwe zimadya njoka masana zomwe zimagwira masana masana. Chikutuluka m'phanga lake m'mawa, imawotha kwa nthawi yayitali m'mamawa. Amakhala nthawi yayitali m'madzi, kutuluka m'mamawa kwambiri, kenako amathawira kunyumba kwake mpaka m'mawa. Njoka sizimakonda kutentha kwambiri, chifukwa chake, nthawi yotentha imabisala m'madzi kapena zitsamba zamchere.
Sizachidziwikire kuti dzina la njoka ndizosambira bwino komanso osambira abwino omwe amadziwa bwino kwambiri zam'madzi ndipo amatha kukhala m'madzi kwa nthawi yayitali. Nthawi zambiri, njoka iliyonse imakhala ndi gawo lawolawo, lomwe limamatirira, kusuntha limodzi ndi mazana awiri mpaka mazana anayi.

- Pomaliza, ikani bandeji yolimba, yosalala yomwe imasunga swab ndi mankhwala opha tizilombo, kuletsa mwayi wofalitsa matendawa komanso kupewa kutaya magazi ena.
Kumanani ndi Njoka Zam'nyanja
Kwa anthu angapo omwe amawira munyanja zotentha za Indian kapena Pacific Oceans, ndizotheka kukumana ndi anthu achilendo ngati awa ngati njoka zam'nyanja. Zikuyimira mabanja ambiri odziwika kwa aliyense kuyambira ali mwana, zokwawa zokwawa.
Mwambiri, njoka ndizofala kwambiri padziko lathuli - malo omwe amakhala ndi osiyanasiyana mosiyanasiyana pokhudzana ndi kukhalapo komanso malo okhala nyengo. Mwina sangapezeke ku Antarctica ndi mpweya kokha, komwe sanapangirepo gawo lokhalamo.
Zokwanira, mitundu yoposa 2600 ya njoka imadziwika padziko lapansi, nthawi zambiri imagawana mabanja 12. Ochulukira kwambiri ndi banja la njoka zokhala ngati njoka, zomwe zimaphatikizapo theka la njoka zonse zomwe zimadziwika ndi sayansi.
Asayansi samadziwa chilichonse chokhudza njoka. Mitundu yosiyanasiyana yamikhalidwe imayesedwa pansi pomwe makolo akale a njoka adataya miyendo yawo ndikusinthira njira yowumbiramo. Akatswiri ena owonetsa zinyama amakhulupirira kuti makolo a njoka amatenga machitidwe awo chifukwa chakusintha kwawo kukhala moyo wopasuka, ena amaimira makolo a njoka ngati anthu okhala m'madzi, pang'onopang'ono kusamukira kumtunda, pomwe ena amati miyendo idatayidwa ndi makolo a njoka chifukwa chokhala pakati pa udzu ndi miyala.
Iliyonse ya njirazi imatha kutenga gawo lalikulu kapena lochepera pakusintha kwa zolengedwa zopanda miyendo izi.
Banja lonse - njoka zam'nyanja (Hydrophiidae) adakhala ndikukhala m'madzi a mnyanja, ndipo ambiri aiwo amabala ana kuchokera kumtunda ndi m'mphepete mwa nyanja. Kusinthika kumalo okhala m'madzi kunasiya zozama zakuya zakuwumbidwe ndi njoka za njoka izi kuti zimayenera kugawidwa ku banja lapadera.
Mitundu 56 ya njoka zam'madzi amadziwika, kuphatikiza 16 genera. Mitundu itatu, kuphatikiza mitundu 14 yapanga subfamily njoka zam'madzi zoterera (Laticaudinae), Mitundu 13, yolumikiza mitundu 39, mawonekedwe subfamily of njoka zokongoletsa (Hydrophilinae).
Njoka zanyanja zokhala ndi tchire sizimalumikizana ndi malo ndipo nthawi zambiri zimapezeka kumayiko ena.
Njoka zam'nyanja zimakhala m'madzi otentha onse am'madzi a Pacific ndi Indian, kuyambira pagombe lakummawa kwa Africa mpaka kugombe lakumadzulo kwa Central America. Nthawi zambiri amapezeka mu Nyanja Yofiila. Kumpoto iwo amakafika ku Japan. M'madzi a Atlantic, njoka zam'madzi sizimachitika, ndipo ndi mtundu umodzi wokha - bicolor bonito (Pelamis platurus) adatha kulowa ku Caribbean kuchokera ku Gulf of Mexico kudzera ku Panama Canal.
Zambiri mwa kuchuluka ndi mitundu ya njoka zam'nyanja ku South China Sea komanso madzi a Mala Archipelago. Njoka zazikulu za njoka zam'madzi zimapezeka kuno, ndipo nthawi zambiri zimakhala kumapeto kwa usodzi. Malo omwe mumawakonda ndi madzi amphepete mwa nyanja osapitirira 5-6 km kuchokera pamtunda, makamaka pafupi ndi milomo ya mitsinje yomwe ikuyenda munyanja, pomwe njoka zam'madzi zimadzipezera chakudya chochuluka. Nthawi zina zimasambira mtunda wa makilomita 50 kuchokera pagombe, pomwe mitundu ina imakhala pamtunda wamakilomita mazana ambiri kuchokera kumtunda.
Dera lakuya lomwe amakhala ndi laling'ono - osapitirira 200-300 metres, ndipo njoka zam'madzi zimakhala mpaka maola awiri popanda mpweya. Izi zimatheka kudzera pakupuma kwapakamwa komanso pakhungu.
Maonekedwe a njoka zam'madzi ndizodziwikiratu zamitundu yambiri - mutu wawung'ono wokhala ndi timiyendo tating'ono, wokutidwa ndi zikopa zazikulu ndikuyenda bwino mthupi. Thupi la njoka zam'nyanja kutsogolo limakhala yopyapyala, yolimba, pomwe imayenda kumbuyo, imakutidwa ndi mbali ndikutha mchira ndi mchira wamitundu-yayikulu, kutalika kwake komwe kumatha kufika 1/6 thupi lonse. Chizindikiro cha njoka zam'nyanja ndi kusowa kwa zishango zamkati, zomwe zimagwira gawo lalikulu kuti njoka zikukwawa pamimba zawo, zomwe zidasoweka panyanja.
Thupi la njoka zam'madzi ambiri limakutidwa mbali zonse ndi mamba ang'onoang'ono ofanana. Njoka zakale kwambiri zam'madzi (Laticauda, Aipysurus ndi ena), omwe adalumikizana ndi nthaka, zopitilira muyeso zingapo zowonjezera zidatsalira pamimba.
Mphuno yomwe ili kumapeto kwenikweni kwa nsonga ya njoka imawalola kupuma pomamatira gawo laling'ono kwambiri la mphuno kuchokera m'madzi. Malo otsegula mphuno amatsekedwa ndikamizidwa ndi valavu yapadera kuti madzi asalowe m'mphuno. M'mphuno zopindika, mosiyana ndi njoka zina zam'madzi, zimakhala pamutu pake. Lilime la njoka zam'nyanja limafupikitsidwa kwambiri ndipo ndi gawo lokhalo lomwe lingatuluke pakamwa.
Njoka zam'madzi zimatha kupumira mkamwa mwawo - nembanemba ya pakamwa imakhala ndi mitsempha yamagazi komanso imatha kutenga mpweya kuchokera kumadzi mwachindunji. Malinga ndi akatswiri ena a zinyama, njoka zam'nyanja zimapuma pakhungu. Chifukwa cha izi thupi, njoka zam'madzi zimatha kukhala pansi pa madzi kwa nthawi yayitali (mpaka maola awiri).
Mano a poizoni opakidwa amakhala kumapeto kwenikweni kwa mafupa. Amakhala afupiafupi, amawerama pang'ono ndipo ali ndi njira yopweteka.
Kuseri kwa ma sumu omwe ali pachiwono chapamwamba pali mano ang'ono, kuchuluka kwa mitundu yosiyanasiyana ya njoka zam'madzi amasiyana 1 mpaka 18. Mwa mphete ya emidocephalus (Emydocephalus annulatus) kumbuyo kwa poyizoni kulibe mano ang'ono konse.
Nsomba zingapo, makamaka ma eel, zimakhala chakudya cha njoka zam'nyanja, nthawi zina zimadyanso crustaceans ndi shrimp. Amasaka, nthawi zambiri, kuchokera pakubisalira kapena kugwira nyama, yomwe, pambuyo pa njoka ndi kubweretsa poyizoni, imafa ziwalo. Nthawi zina njoka zam'nyanja zimagwiritsa ntchito njira zoyambira kusaka, pomwe njokayo imagona pamwamba pa madzi, ndikuyembekezera nsomba zazing'ono ndi nyama zina zazing'ono kuti zisonkhanitse kuzinthu zachilendo. Kusuntha kwakuthwa kwa thupi la njoka yam'nyanja - ndipo imodzi mwa nsomba ija yagwidwa.
Njoka zam'nyanja zimamwa nyama yonse.
Kubadwanso kwa njoka zam'madzi kumachitika m'njira zosiyanasiyana. Mitundu ina yogwirizana kwambiri ndi kumtunda ndi kuyikira mazira. Nyoka zikuluzikulu zam'nyanja ndi ovoviviparous, mitundu yambiri imakhala ndi placenta yakale yomwe imagwirizanitsa mluza ndi thupi la amayi. Mitundu ina imabereka ana mwachindunji m'madzi, ena amapita kumtunda chifukwa chaichi. Chonde cha njoka zam'nyanja ndizochepa kwambiri - ma 1-2 awiri okha.
Amakwanitsa chaka chimodzi.
Mwa oimira owala kwambiri a banja la njoka zam'madzi amatha kusiyanitsidwa malo ogulitsira akulu (L.semifasciata), yofikira kutalika kwamitala iwiri ndi makulidwe akuya masentimita 7-8
Njoka zam'nyanjazi ndizofala kumadzulo kwa Pacific Ocean, kuchokera ku zilumba za Ryukyu mpaka Samoa. Mchira wambiri wamapiri m'dera la Phillipin wakhala ukulozera kwa asodzi aku Japan omwe amagwira njoka chifukwa cha chikopa, chomwe chimagwiritsidwa ntchito popanga zikumbutso ndi haberdashery, komanso nyama, yomwe imagwiritsidwa ntchito ku Japan ku zakudya zosuta kapena zotsekemera.
Mwa njoka zam'nyanja zofiirira, zodziwika bwino mphete yooneka ngati mphete (Laticauda laticaudata) Mtunduwu wafalikira kuyambira ku Ryukyu Islands kupita ku Australia komanso kuchokera ku India kupita ku Solomon Islands. Thupi lake limakhala lowala bwino, pomwe mbali zake zakuda zimasinthana. Mbali yamkati yapakidwa utoto wonyezimira wamtambo wonyezimira. Njoka yokongola iyi ndiyofala kwambiri pamatanthwe a korali komanso pakati pa zomerazo.
Njoka zocheperako za njoka zam'nyanja zopyapyala zimaphatikizapo ringed emidocephalus (Emydocephalus annulatus), yogawidwa kuchokera pagombe la Ryukyu kupita kugombe la Australia ndi mitundu isanu ndi iwiri ya Aipysurus okhala m'madzi aku Southeast Asia ndi North Australia.
Njoka zam'nyanja za Foxtail sizingosinthidwa kuti zizikhala pamtunda, pomwe sizingatheke konse. Pamalo olimba, sizingathe kuyenda chifukwa kulibe zotchingira pamimba. M'madzi, njoka zam'madzi izi zimamva, monga nsomba.
Njoka zam'madzi zaphinjo zimatha kukhala moyo wawo wonse kunyanja, ndipo ndi mitundu yochepa yokha yomwe sikusankhidwa pamtunda kuti ibereke ana. Njoka zonse zam'madzi zam'madzi zimakhala ndi ovoviviparous.
Zojambula zakunja kwa njoka zam'nyanja zodzaza ndi mutu wochepa komanso mbali yaku thupi yotsika, yomwe imasiyana kwambiri ndi mbali yakumaso komanso yayikulu kwambiri, komanso kupezeka kwa mchira wamphamvu ngati (kapena ngati-ngati-mwala). Kapangidwe kameneka kamafanana kumathandizira kuti michira yopendekera ipange mataya othamanga ikamagwira chakudya mu khola lamadzi pomwe kulibe chithandizo pansi kapena pansi. Pankhaniyi, misa yakumbuyo imathandizira mutu ndi mapapo amtsogolo.
Nayi kufotokoza kwa mitundu yamitundu yomwe imapezeka ndi mitundu:
Dovetail Yomangidwa (H. fasciatus) ili ndi mbali yayikulu yam'mimba (nthawi 4-5 yopyapyala kuposa kutsogolo). Imakhala yakuda kutsogolo, komwe kumakhala mawanga achikasu m'mbali mwake, ndipo mawanga amdima akhungu amayikidwa kumbuyo kwa thupilo kumbuyo. Imapezeka ku Indian Ocean ndi madzi a Mala Archipelago.
Zingwe zopota (H.cyanocinctus,, wopaka utoto wonyezimira wamtambo wakuda ndi wamtambo wakuda, umafika kutalika kwa mita 2. Ndizofala munyanja zotentha za kunyanja ya Pacific ndi India, pakati pa zisumbu za pachilumba cha Malaysia ndikufikira kumpoto ku Japan.
Spiral dovetail (H.spiralis) imayimilira kutalika kwake - pafupifupi 3 mita. Kugawa kwake kuli kofanana ndi tepi dovetail.
Osati otsika kwambiri kwa iye kukula chisangalalo chokoma (MaHelegans), yemwe amakhala m'madzi a kumpoto kwa Australia ndikuchokera kuzilumba za Aru. Kutalika kwake kumatha kupitirira 2 metres.
Nyimbo ziwiri bonito (Pelamis platurus- - njoka yaying'ono yam'nyanja (mpaka mita imodzi) yotalika mutu kuchokera kumtunda ndi khosi lakuthwa, thupi loponderezedwa kuchokera kumbali ndi mchira wamiyala. Mtundu wakuda, wakuda bii mbali yakumaso kwa njoka zam'nyanja iyi umasiyana ndi utoto wachikasu wam'mimba mwa thupi. Mitundu iwiriyi mwadzidzidzi, popanda kusinthana, imasinthana wina ndi mnzake. Mchirawo umakutidwa ndi mawanga amdima akuda. Komabe, m'malo osiyanasiyana a bonito, mitundu yawo imatha kusiyanasiyana.
Njoka yam'nyanja, bonito yamitundu iwiri, imapezeka m'malo ambiri ku Indian ndi Pacific Oceans - kuchokera pagombe la ku Africa, kupita kumadzulo kumadzulo kwa Central America. Mtundu wake ndiwotalikirapo kuposa magawo anyoka yonse yam'nyanja. Imapezeka kumwera ku Cape of Good Hope komanso kumpoto kwa Nyanja ya Japan.

Adasinthidwa bwino kukhala m'madzi otseguka a nyanja komanso ma microcephals ochepa (Microcephalophis gracilis) okhala ku Indian ndi Western Pacific Oceans. Awa ndi njoka zazing'ono (70-80 cm) yokhala ndi mutu waching'onoting'ono ("microcephalus" - "mutu wawung'ono") ndi mbali yakuonda ya thupi, yosiyana kwambiri ndi kumbuyo kwakumaso. Thupi lonse limakutidwa ndi mamba ofanana a hexagonal okhala ndi mbali zolimba zolimba.
Njoka zambiri zam'madzi zimapanga magulu akuluakulu m'malo amtunda wawo. Pankhaniyi, zikuonekeratu kupenda (Astrotia stokesii) Utoto wowala kwambiri ngati mphezi yakunyanja yakubwera mpaka 1.5 m umatha kupanga masango akuluakulu ngati matepi mpaka mita angapo mulifupi ndi kupitirira makilomita zana. Riboni wakuda bii la njoka zikuluzikulu masauzande ambiri nthawi zina zimayamba kuchokera pomwepo.
Zomwe zimayambitsa izi zimadziwika. Izi mwina zikuchitika chifukwa cha kubadwanso kwakukulu kwa zinthu zakuthambo.
Payokha, tiyenera kuganizira za poizoni wa njoka zam'nyanja. Pafupifupi onsewo ali ndi ma fangala ogwidwa ndi poyizoni. Ziwopsezo za njoka zam'nyanja zina ndizambiri poizoni kuposa ziphe za mitundu yoopsa kwambiri yamtchire.
Njoka yaukali kwambiri yam'madzi imaganiziridwa Njoka Ya Dubois Nyanja (Aipysurus duboisii), pomwe chakumwa chake chili pamalo achitatu padziko lonse lapansi la njoka (pambuyo pa njoka ya taipan ndi ya bulauni).
Njoka ya Dubois Nyanja imapezeka m'mbali mwa gombe lakumpoto la Australia ndi nyanja zam'madzi a Mala Archipelago mpaka mamita 30. Amakonda malo okhala ndi zomera pansi pamadzi pakati pa ma corals, pamchenga ndi dothi lamchere. Kutalika kwa njoka izi kuli pafupifupi mita 1, koma kumatha kutalika mita ndi theka. Imapaka utoto wonyezimira komanso wamtundu wakuda wachisoni kumbuyo ndi m'mbali. Chakudya cha njoka za Dubois ndi tinsomba ting'onoting'ono, ma eel ndi nyama zina zapansi, zomwe amameza zathunthu, olumala ndi poyizoni. Kuwopsa kwa poizoni wa njokayi tingayerekeze ndi chifuwa cha mamba, koma, mosiyana ndi ichi, sikuti timayambitsa zotupa. Kuchita kwa poizoni kumafikira kumanjenje, makamaka, kukakamiza kupuma, chifukwa chomwe wozunzidwayo amafa chifukwa chokhutitsidwa. Komabe, munthu sayenera kusambira modabwitsa pakuwona njoka yam'nyanja Dubois - ichi ndi cholengedwa chamtendere, ndipo sichisonyeza kukwiya popanda chifukwa. Zachidziwikire, simuyenera kuseka njoka kapena kuigwira mchira, pokhapokha, ndicholinga chanu kuti mumve kuluma komanso kuchita ngati poyizoni.
Ikalumidwa ndi njoka yam'nyanja, poizoni wambiri amalowa m'matupi a omwe akuwonongeka kuposa omwe akulumidwa ndi abale awo. Kuphatikiza apo, njoka zambiri za kunyanja siziluma popanda chifukwa. Asodzi a ku India mosamala amatenga njoka zam'madzi zomwe zimagwidwa mu maukonde awo ndi manja awo. Iwo akudziwa. kuti njoka yam'madzi ikuluma. ngati mutagwira kwambiri komanso kupweteka.
Poizoni wa njoka zam'madzi amachokera mu thupi. Zotupa ndi zotupa pamalo akumwa sizimachitika. Zambiri zimayambika - kufooka, kusokonezeka kwa kayendedwe ka kayendedwe. kusanza, kukokana, kupuma movutikira, komanso ngakhale ziwalo zathunthu zopumira. Ngati simupereka chithandizo choyamba kwa amene akukhudzidwayo, ndiye kuti patatha maola ochepa munthu akhoza kufa.
Komabe, kuchuluka kwaimfa kumakhala kochepa chifukwa chakuti njoka zam'nyanja zimabayira poizoni wocheperako ndikuluma.
Njoka zambiri zam'madzi zimakhala ndi poizoni wotsika, zomwe sizikuwononga thupi.
Chifukwa chiyani njoka zam'nyanja zimafunikira poyizoni?
M'mikhalidwe yakukhala pakati pa miyala yamiyala ndi matanthwe, ngati simufa ziwalo, imatha kubisala m'malo osavomerezeka komwe sizingatheke. Chifukwa chake, njoka zimagwiritsa ntchito kupha nyama zawo m'njira zosavuta motere.
Ponena za mitundu yosiyanasiyana, kwa iwo, lamulo loyamba la kulumikizana ndi okhala pansi pamadzi ndilovomerezeka - musawakhudze, osawawopsa ndipo musawakhumudwitse. Izi zikuthandizira kupewa zovuta zambiri pakutsamira.
Kodi ndani amene akuopsa njoka zamadzi?
Monga tafotokozera pamwambapa, mdziko lamakono, mdani wowopsa kwambiri komanso wotchuka kwambiri wazinthu izi ndi munthu yemwe zochita zake zochulukirapo zimayipitsa tsoka la madzi. Komabe, sikuti ndi adani a okhawo omwe ndi adani. Adani odziwika a njoka zamadzi ndi:
- nsomba zodyedwa ndi mbalame,
- mbalame zovunda
- ziweto zazikulu
- Ng'ona
