Kwa Onse Okonda Ziweto
Lowani m'dziko losangalatsa la akamba ndi akamba ndi mndandanda wathu wathunthu. Dziwani zaupangiri wa chisamaliro, zambiri zamitundu, ndikujowina gulu lomwe limakonda kwambiri zodabwitsa izi!
Akamba amapezeka m'malo osiyanasiyana, kuphatikizapo zipululu. Mitundu ina, monga kamba ya m’chipululu, yasintha kuti ikhale yowuma ndipo imatha kukhala ndi moyo popanda kumwa madzi kwa nthawi yaitali. Komabe, kuwonongeka kwa malo okhala ndi ziwopsezo zina zachititsa kuti anthu achuluke m’madera ambiri.
Akamba nthawi zambiri amakhala nyama zokhala paokha, koma nthawi zina amakhala m’magulu. Maguluwa nthawi zambiri amapangidwa kuti akwere, kumanga zisa, kapena kugona. Komabe, mitundu ina, monga kamba ya Galapagos, imatha kupanga magulu amagulu omwe amakhala kwa nthawi yayitali. Zosintha zamaguluwa zimatha kusiyana kwambiri malinga ndi zamoyo ndi malo omwe amakhala.
Akamba ndi zolengedwa zochititsa chidwi, koma kodi ali ndi zikhadabo? Yankho ndi lakuti inde! Komabe, zikhadabo zawo sizinapangidwe ndi keratin ngati misomali ya munthu, koma zimapangidwa ndi zinthu zomwezo ndi zipolopolo zawo. Zikhadabo zimenezi zimathandiza akamba kukwera, kukumba, ndi kudziteteza. Ndikofunikira kusunga zikhadabo zawo kuti asachuluke komanso kuvulala komwe kungachitike.
Akamba samadziwika ndi luso lawo losambira, koma kodi amatha kuyandama pamadzi? Yankho ndi inde, koma si luso lachibadwa. Akamba amatha kuyandama ngati atagwira mpweya ndipo matupi awo ali ndi mpweya wokwanira, apo ayi adzamira.
Akamba amadziwika kuti amakhala ndi moyo wautali komanso amakula pang'onopang'ono. Komabe, mitundu ina imatha kukula kwambiri. Kamba wamkulu wa Galapagos, mwachitsanzo, amatha kulemera mapaundi 900 ndikukula mpaka mamita anayi m'litali. Kamba wamkulu wa Aldabra, mtundu wachiwiri waukulu kwambiri, amatha kulemera mapaundi 4 ndipo amafika kutalika kwa 550 mapazi. Mitundu ina, monga kamba waku Russia, ndi yaying'ono kwambiri ndipo imangokulira mpaka mainchesi 4.5-8 m'litali. Kukula kwa kamba kumadalira mtundu wake, malo ake, ndi kadyedwe.
Hibernation ndi chikhalidwe chachilengedwe kwa nyama zambiri, koma kodi ndi chimodzimodzi kwa akamba? Ngakhale kuti mitundu ina ya akamba amagona kuthengo, ena satero. Lingaliro logona kapena kusagona zimatengera zinthu zosiyanasiyana kuphatikiza kutentha, kupezeka kwa chakudya, komanso komwe kuli. M'nkhaniyi, tiwona ngati kubisala ndi chikhalidwe chachilengedwe cha akamba komanso ndi zinthu ziti zomwe zimakhudza chisankho chawo chogona.
Akamba amadziwika kwambiri chifukwa chokhala okha. Amakonda kukhala okha ndipo amangobwera pamodzi nthawi yokweretsa.
Akamba ali m’gulu la zokwawa zotchedwa Testudines. Ngakhale kuti nsagwada zawo zilibe mano, zili ndi milomo yakuthwa yomwe imatha kutafuna zomera zolimba.
Kamba nthawi zambiri amadziwika ndi zipolopolo zawo zolimba zoteteza, koma kodi alinso ndi michira? Mosiyana ndi zomwe anthu ambiri amakhulupirira, akamba amakhala ndi michira, ngakhale amasiyana maonekedwe ndi kukula pakati pa mitundu yosiyanasiyana.
Akamba sakhala m’nyanja. Ngakhale kuti mitundu ina ya akamba imakhala ya m’madzi, akamba amakhala akumtunda ndipo amazolowera kukhala pamtunda.
Akamba amabwera mosiyanasiyana, kuyambira pa kapalapala kakang'ono mpaka ku kamba wamkulu wa Galapagos, yemwe amatha kulemera mapaundi 900.
Akamba ali ndi makutu, koma sawoneka kunja kwa mitu yawo. M'malo mwake, makutu awo amakhala mkati mwa zigaza zawo, zotetezedwa ndi fupa. Ngakhale zili choncho, akamba amatha kumva mawu ndikugwiritsa ntchito mphamvuyi polankhulana komanso kuyenda.
