Njoka yam'nyanja yamabokosi (Aipysurus eydouxii) idatchulidwa ndi katswiri wazachilengedwe waku France.
Zizindikiro zakunja za njoka yamiyala yamabulo.
Njoka yam'mbali yamiyala yayitali pafupifupi mita imodzi. Thupi lake limafanana ndi thupi lokulirapo lokutira lokutidwa ndi masikelo akulu ozungulira. Mutu ndi wawung'ono; m'malo mwake maso akulu amaonekera. Kirimu wa khungu, bulauni kapena wobiriwira. Pali mikwingwirima yakuda yomwe imapanga mawonekedwe owonekera.
Monga njoka zina zam'nyanja, njoka yolamulidwa ija ili ndi mchira wathyathyathya wofanana ndi chiwongolero ndipo imagwiritsidwa ntchito kupalasa posambira. Mphuno za valavu zopangidwa mwapadera zimatsekedwa mukamizidwa m'madzi. Zoyipa mthupi zimakonzedwa pafupipafupi komanso mosiyanasiyana. Mamba osalala osalala okhala ndi m'mbali mwamdima amapanga mizere 17 pakati pa thupi. Mbale zam'mimba zimasiyana kukula mthupi lonse, kuchuluka kwake kumachokera ku 141 mpaka 149.
Kufalitsa njoka yam'mbali yamiyala.
Mtundu wa njoka yam'mbali ya marble ukuyambira kumpoto chakumpoto kwa Australia kudutsa Southeast Asia mpaka ku South China Sea, kuphatikiza Gulf of Thailand, Indonesia, West Malaysia, Vietnam ndi Papua New Guinea. Njoka zam'madzi a Marble zimakonda makamaka madzi otentha a m'nyanja ya Indian komanso kumadzulo kwa Pacific.
Malo okhalapo njoka yamiyala yamiyala.
Njoka zam'madzi za Marble zimapezeka m'matope, m'matope, m'misewu, ndi m'madzi osaya, mosiyana ndi njoka zina zam'nyanja zomwe zimapezeka m'madzi oyera ozungulira miyala ya coral. Njoka zam'madzi za Marble zimakonda kupezeka m'misewu, malo osaya komanso malo ogulitsira madzi ndipo nthawi zambiri zimalumikizidwa ndi magawo am'matope, koma sizimapezeka kwenikweni kumagawo olimba. Nthawi zambiri amasambira kumtunda m'mitsinje ikutsikira kunyanja.
Nthawi zambiri amakhala akuya mita 0.5, chifukwa chake amawoneka kuti ndi owopsa kwa anthu. Izi ndi njoka zenizeni za m'nyanja, zimasinthidwa kwathunthu ndi malo am'madzi ndipo sizimawoneka kumtunda, nthawi zina zimapezeka m'malo ophatikizika am'madzi obwerera. Njoka zam'madzi za Marble zimapezeka patali ndi nyanja, zimakwera m'mapiri a mangrove.
Kudya njoka yam'mbali yamiyala.
Njoka zam'madzi a Marble ndi mitundu yachilendo pakati pa njoka zam'nyanja zomwe zimakonda kudyetsa kokha caviar ya nsomba. Chifukwa cha zakudya zosazolowereka zoterezi, adatsala pang'ono kutaya mayini awo, ndipo zilonda zam'mimba zimakhala zochepa, chifukwa poyizoni safunika pakudya. Njoka zam'madzi za Marble zapanga kusintha kwakutengera mazira: adapanga minofu yolimba ya pharynx, zishango pamilomo, kuchepa ndi kutayika kwa mano, kuchepa kwambiri kukula kwa thupi komanso kusapezeka kwa ma dinucleotides mu jini la 3FTx, chifukwa chake, achepetsa kwambiri poyizoni wa poyizoni.
Kuteteza njoka yam'mbali yamiyala.
Njoka yam'mbali yamiyala ili ponseponse, koma imagawidwa mosagwirizana. Pali kuchepa kwa kuchuluka kwa mitunduyi m'chigawo cha Quicksilver Bay (Australia). Amapezeka mochuluka m'mitengo ya trawler ku West Malaysia, Indonesia, komanso zigawo za Kum'mawa kwa nsomba za shrimp trawl ku Australia (njoka zam'madzi zimapanga pafupifupi 2% ya nsomba zonse). Njoka zam'nyanja nthawi zambiri zimapezeka m'malo opha nsomba, koma nsomba zomwe zimadya nthawi yomwe akusodza ndizosavuta ndipo sizowoneka ngati chiwopsezo chachikulu.
Chikhalidwe cha anthu sichikudziwika.
Njoka yamchere ya marble ili mgulu la "Osadandaula Kwambiri", komabe, pofuna kuteteza njokazo, ndibwino kuti muziyang'anira zomwe zagwidwa ndikukhazikitsa njira zochepetsera kugwidwa. Palibe njira zenizeni zomwe zingagwiritsidwe ntchito kuteteza mtundu uwu wa njoka m'malo awo. Njoka yam'mbali yamiyala ya marble pakadali pano yatchulidwa pa CITES, msonkhano womwe umayang'anira malonda apadziko lonse lapansi amitundu ndi zinyama.
Njoka zam'madzi za Marble zimatetezedwa ku Australia ndipo amalembedwa ngati mitundu yam'madzi pamndandanda wa department of Environment and Water Resources mu 2000. Iwo ndiotetezedwa ndi Environment, Biodiversity and Conservation Act, yomwe yakhala ikugwira ntchito ku Australia kuyambira 1999. Lamulo Laku Australia Loyendetsa Usodzi limafunikira kupewa kupha nsomba mosaloledwa kuti tipewe kugwira nyama zomwe zatsala pang'ono kutha monga njoka zam'madzi zam'madzi. Njira zotetezera cholinga chake ndikuchepetsa anthu omwe agwidwa ngati asodzi mwa nsomba za shrimp pogwiritsa ntchito zida zapadera pamaneti.
Kutengera njoka yamiyala yam'nyanja kumalo okhalamo.
Njoka za m'nyanja ya Marble zimakhala ndi mchira wochepa kwambiri, womwe umakhala ngati wopalasa. Maso awo ndi ang'ono, ndipo mphuno za valavu zili pamwamba pamutu, zomwe zimalola njoka kupuma mpweya mosavuta posambira kumtunda kwa nyanja. Ena mwa iwo amatha kuyamwa mpweya kudzera pakhungu, monga amphibiya, motero amakhala omizidwa m'madzi kwa maola angapo osakhala otakataka.
Njoka yamiyala yam'madzi ndi yoopsa bwanji.
Njoka yam'mbali yamiyala samenya nkhondo pokhapokha itasokonezedwa. Ngakhale anali ndi poyizoni, palibe chilichonse chokhudza anthu olumwa. Mulimonsemo, njoka yam'madzi ya marble ili ndi zibambo zazing'ono zomwe sizingawononge kwambiri.
Sikoyenera kuyesa ndikukhudza njoka yotsukidwa mwangozi kumtunda.
Ikapanikizika, imapindika, imapinda thupi lonse ndikutembenuka kuyambira mchira mpaka kumutu. Mwinamwake amangonamizira kuti wafa kapena akudwala, ndipo kamodzi m'madzi, amatha msanga msanga.
Ndipo ichi ndi chifukwa china chomwe simuyenera kukhudza njoka yamiyala, ngakhale ikuwoneka ngati yosasunthika. Njoka zonse zam'nyanja ndizowopsa, njoka yamiyala ili ndi poizoni wofooka kwambiri, ndipo siyifuna kugwiritsira ntchito poizoni pakuluma kopanda ntchito. Pazifukwa izi, njoka yamiyala yamabokosi sionedwa ngati yowopsa kwa anthu. Komabe, musanaphunzire za njoka yamiyala yam'madzi, ndikofunikira kudziwa zizolowezi zake.
