Lapho sicabanga ngezitshalo ezidlayo, uhlobo oluthile luvele lufike engqondweni, i- UDionaea muscipula. Waziwa ngo I-Venus flytrap, ikhiqiza izicupho ezingelutho ngaphandle kwamaqabunga alungisiwe aklanywe ngokuphelele ukubamba noma yisiphi isinambuzane, ngokungaqondile, esithinta izinwele ezingaphakathi.
Izitshalo ngokuvamile zihamba esikalini sesikhathi sihamba kancane kakhulu kunalokho esikwaziyo ukukuqonda, kepha lezi zingibe, ukuvalwa ngemizuzwana, kwenze i-Venus flytrap esinye sezilwane ezidla kakhulu emhlabeni. Kodwa, kungani?
La UDionaea muscipula Kuyisilwane esidla inyama esihlala emaxhaphozini nasezimanzini ezimanzi eningizimu-mpumalanga ye-United States, esitholakala ikakhulu eNyakatho Carolina naseNingizimu Carolina. Ikhula kuma-rosettes angakhuphuki kakhulu emhlabathini, angabi ngaphezu kwamayintshi amane. Iqabunga ngalinye lakhiwe ngama-lobes amabili ngaphakathi okunezinwele ezintathu ezizwelana kakhulu nokuthinta.
Uma isisulu esingaba khona sithinta izinwele ezimbili ngasikhathi sinye, noma esinye futhi futhi kwesinye ngemizuzwana engaphansi kwamashumi amabili, isicupho sivaleka ngokuzenzekelayo. Wenza kanjani umuntu odla inyama? Le ndlela ayikaqondakali kahle, yize kwaziwa ukuthi lapho kuthintwa izinwele ezibucayi kutholakala isenzo esingasakazeka phakathi kwezingibe zesicupho futhi sivuselele amaseli aso kanye nalezo zomthambo ophakathi.
Lapho isinambuzane singakwazi ukubaleka, isicupho sizovala kakhulu kuze kube yilapho kwakheka "isisu" lapho kuzogaywa khona. Ngesikhathi kwenziwa lokhu, ama-enzyme wokugaya ukudla azogaya izingxenye ezinesinambuzane, kusale kuphela 'igobolondo' lesilwane ngemuva kwezinsuku eziyishumi zokugaya. Leli gobolondo lizokwenziwa nge-chitin, into elula kakhulu umoya ongayithatha kalula, ishiye isicupho silungele ukuzingela okusha.
Kepha i-Ventr flytrap nayo inokwelashwa kwezinambuzane: umpe wezimbali zalo. Intwasahlobo ngayinye, iziqu ezingaba ngamasentimitha ayisithupha ubude lapho kuhluma khona izimbali ezinhle ezimhlophe ezenzelwe ukuthi impova ikwazi ukuzondla futhi, ngenhlanhla, iqhubekisele phambili izinhlobo zalesi sidlo esidla inyama esimangalisayo.
