Njoka ya chi Malay (Caloselasms rodostoma) imatha kutchedwa njoka yoopsa kwambiri ku Southeast Asia. Njokayi imapezeka ku Vietnam, Burma, China, Thailand, Malaysia, komanso pazilumba: Laos, Java ndi Sumatra, okhala m'nkhalango zam'malo otentha, nkhalango zamatabwa ndi minda yambiri.
Ndi m'minda yomwe nthawi zambiri anthu amakumana ndi njokayi. Nthawi yogwira ntchito, anthu nthawi zambiri sawona njoka yabodza mwakachetechete ndikupeza kuti alumidwa. Kutalika kwa njokayi sikupitilira mita, koma musapusitsidwe ndi kukula kwake, popeza thunzi laling'ono lowala limabisa pakamwa pake malekezero awiri owopsa ndi ma gland omwe ali ndi poyizoni wamphamvu wa hemotoxic. Amawononga maselo amwazi ndikudya minofu. Poizoniyo amapukusa pang'onopang'ono ozunzidwa (mbewa, makoswe, abuluzi ang'ono ndi achule) kuchokera mkati, pambuyo pake njokayo imameza nyama yomwe yatha kumapeto.
Palibe njira yothanirana ndi poyizoni wamutu wa njoka wachi Malay, motero madotolo amatha kubaya chimodzimodzi ndikuyembekeza kuchita bwino. Kuopsa kumadalira kuchuluka kwa poyizoni, msinkhu komanso mawonekedwe amthupi la munthu, komanso momwe angatengere kuchipatala posachedwa. Kuti apulumutse moyo wamunthu, thandizo liyenera kuperekedwa mkati mwa mphindi 30 kuchokera pomwe waluma. Popanda chithandizo chamankhwala, munthu amatha kufa.
Chifukwa china chowopsa pakamwa ndi chakuti sikophweka kuzindikira. Njoka yaying'onoyi imatha kukhala ndi utoto kuchokera ku pinki wonyezimira mpaka bulauni wonyezimira wokhala ndi zigzag yakuda kumbuyo, yomwe imalola kuti iphatikize m'nkhalango ya masamba akugwa. Komabe, njokayi ili ndi chinthu china chomwe chimapangitsa kuti isawonekere: njokayo imagona osasunthika, ngakhale munthu atayandikira. Njoka zapoizoni zambiri monga mphiri, mamba ndi njoka zamatsenga zimachenjeza munthu za kupezeka kwawo pofukiza nyongolotsi, kugundana kapena kulira mokweza, koma osati njoka yaku Malawi. Njoka iyi imagona osasunthika mpaka mphindi yotsiriza, kenako ndikuukira.
Mphutsi zamkamwa, monga njoka zamphongo, zimadziwika chifukwa chamapenga othamanga ndi mphepo yosachedwa kupsa mtima. Njotayi yadzipotokola, njoka imawombera kutsogolo ngati kasupe, ndipo imaluma pang'ono, kenako imabwerera pamalo ake oyamba. Osapeputsa mtunda womwe njoka imatha kuyenda. Pakamwa pake nthawi zambiri amatchedwa "njoka yaulesi" chifukwa nthawi zambiri akaukilidwa samakwawa ngakhale pang'ono, ndipo mutabwerera patatha maola ochepa mutha kukakumananso nawo pamalo omwewo. Kuphatikiza apo, anthu aku Asia nthawi zambiri amapita opanda nsapato, zomwe zimapangitsa kuti zinthu zizikhala zovuta. Ku Malaysia kokha, kulumidwa njoka 5,500 kudalembedwa mu 2008.
Amagwira ntchito makamaka usiku, akamatuluka kukasaka makoswe, ndipo masana nthawi zambiri amagona, kusamba ndi dzuwa.
Zazikazi za mutu wanjoka wachi Malay zimayikira mazira pafupifupi 16 ndikusamala zowotchera. Nthawi yosakaniza imatenga masiku 32.
Makoswe obadwa kumene ali kale ndi poyizoni ndipo amatha kuluma.
