Bilimankhwe - wokhala lina Africa, anapeza kutchuka kuyamika luso lapadera kusintha khungu. Izi pang'ono buluzi kutalika kwa masentimita 30 okha akhoza kusandulika kukhala wakuda, pinki, zobiriwira, buluu, wofiira, wachikasu. Asayansi ambiri maphunziro osiyanasiyana kuti apeze momwe ndi bilimankhwe amasintha mtundu, ndi zimene zimaphatikizapo. Iwo anali ankaganiza kuti Choncho adziwonetsera ngati maziko ozungulira. Koma kunapezeka kuti lidali kopanda.

buluzi ili lokha ndi wapadera. Iye amaona ngati chinjoka, nthawi zambiri amasintha wa khungu, wotchi atakhala pa nthambi za mitengo pokonzekera woberedwa, amene analanda lilime yaitali. maso ake moyo osiyana, osatembenukira ku madera osiyana. Bilimankhwe amasintha mtundu chifukwa maselo wapadera - chromatophores. khungu lake chimaonekera, choncho ndi bwino looneka maselo munali pigment a mitundu yosiyanasiyana.

Akatswiri sanathe kumvetsetsa mmene chameleon amasintha mtundu, ndipo n'chifukwa chiyani zimenezi zikuchitika kwa nthawi yaitali. Iwo ankayenera kuti iye zofunika kubisa. Ndipotu, mtundu Mwachitsanzo, mu wobiriwira, buluzi akhoza masked mitengo pothawa zilombo zolusa komanso kuyembekezera akuvutika awo. Ndithudi, njira ya kusanduka chameleons ambiri aphunzira kukhala ndi mtundu ndi chitsanzo cha mdani wake - monga mbalame kapena njoka.

Akatswiri ofufuza wasonyeza kuti ndondomeko ya mmene chameleon amasintha mtundu, amadalira kwathunthu chikhalidwe chake. khungu zimasiyanasiyana mmene alili - zosiyanasiyana monga mantha kapena chimwemwe. Mwina zimadalira kutentha. Mu Africa, chameleons ambiri wakuda m'mawa kukopa dzuŵa, koma angasangalatse, sizinali choncho otentha. mitundu Variegated ntchito pachibwenzi kuti kukopa mamembala a stati zosiyana.

Chromatophores chameleons zili zigawo zozama za khungu ndipo mwachindunji amadalira wamanjenje dongosolo. Mu wosanjikiza chapamwamba ndi wofiira ndi wachikasu munali maselo pigment. Lotsatira ili crystalline mankhwala guanine, amene molondola imabereka mtundu buluu. Patsinde - melanophores, ndi inki udindo chikasu ndi wakuda mitundu muli melanin. momwe granules pigment selo ili, kwathunthu bwanji mtundu. Bilimankhwe - chidwi kwambiri nyama.

Ngati iwo anaikira mu mzinda wa khungu, zidzakhala mandala, ndipo ngati pa izo wogawana anagawira, ndiye utoto mtundu kwambiri.

Mitsempha mathero chromatophores kugwirizana ndi ubongo, kumene pakubwera lamulo kusintha. Kodi ndi bilimankhwe amasintha mtundu, izo angayerekezedwe ndi phale limene mitundu, kusakaniza, kupanga mithunzi zatsopano. Chifukwa umatha kusintha khungu, buluzi izi chapeza wotchuka kwambiri. Lero, utoto nsalu zinthu zina, iridescent mithunzi osiyana kapena kusintha iwo, chameleons.

Ngakhale zikuoneka kuti kusintha mtundu, buluzi akufuna chinthu, si. Iye sanali kulabadira kwa maziko. Khungu sukhala wosangalala, kutengeka nako kutentha mpweya, koma osati malo. Choncho, maganizo pamene bilimankhwe ndi pa chessboard, ndiye izo zidzakhala maselo wakuda ndi woyera, ndi thunthu cholakwika.
