Njengazo zonke izilwane ezincelisayo, amahhashi angakwazi ukubhukuda ngokwemvelo. Ngokushesha nje lapho izinselo zisuka phansi, ngokuzenzakalelayo ziqala ukukhahlela imilenze njenge-trot esheshayo. Amasondo asenkantolo asebenza njengamagwebu amancane ayisa ihhashi phambili.
imibuzo ejwayelekile ukubuzwa
Ihhashi lingakhala?
“Amahhashi nazo zonke ezinye izilwane azikhali ngenxa yezizathu ezingokomzwelo,” kusho uStephanie Milz. Ungudokotela wezilwane futhi unomsebenzi wokuzilolongela amahhashi e-Stuttgart. Kodwa: Amehlo ehhashi ayakwazi ukuchela, isibonelo uma kunomoya ngaphandle noma iso livuvukele noma ligula.
Ingabe amahhashi angabona imibala?
Kulolu cwaningo kuvele kwacaca ukuthi amahhashi ayakwazi ukubona cishe wonke umbala obonakala kubantu, kodwa ngemibala ehlukene kunabantu njengoba enezinhlobo ezimbili kuphela zamakhoni. Ihhashi libona indawo yalo ngombala oluhlaza okwesibhakabhaka nokuphuzi ngokuluhlaza kanye nokumpunga.
Imuphi umbala amahhashi angawuthandi?
Ngakho-ke amahhashi angabona okuluhlaza okwesibhakabhaka nokuphuzi kahle kakhulu. Empeleni, amahhashi athanda imibala ekhanyayo, kuyilapho imibala emnyama noma emnyama ibonakala isongela kuwo. Bangakwazi ukuhlukanisa okumhlophe, okubomvu, okuphuzi, nokuluhlaza okwesibhakabhaka komunye nomunye. Kodwa hhayi onsundu, oluhlaza, noma ompunga.
Imiphi imibala amahhashi ayibona kabi?
Amahhashi anezinhlobo ezimbili kuphela zamakhoni. Ngenxa yalokho, bayakwazi ukubona imibala efana noluhlaza okwesibhakabhaka nophuzi kahle kakhulu, kuyilapho bengaboni umbala wesignali obomvu.
Ngingabona kanjani uma ihhashi lingaboni kahle?
Izimpawu zokuqala ezibukhali ze-glaucoma wukuklolodela kweso, i-conjunctiva ebomvu, ukufiphala kwe-cornea, nokuvuleka komfundi. Ezinye izilwane zibonisa kuphela ukuziphatha okuhlukile futhi ziba nokukhathazeka okungajwayelekile.
Amahhashi asabela ngamiphi imibala?
Ngakho-ke, ososayensi bacabanga ukuthi amahhashi abona imibala ngendlela efanayo kubantu abanobuthakathaka obubomvu-luhlaza. “Amahhashi angabona okuluhlaza okwesibhakabhaka nokuphuzi kangcono,” kusho uDkt. Willy Neuman. Umbala wesignali obomvu wesithiyo esifundweni, ngakolunye uhlangothi, ubamba iso lomgibeli kuphela, ihhashi aliboni.
Ungabona kanjani ukuthi ihhashi aliboni?
Ukuze ahlole amehlo, udokotela wezilwane uzokhanyisa ithoshi elikhethekile esweni. Angabona ngokusabela kwehhashi ukuthi ngabe ikhona yini inkinga. “Ngokuvamile ihhashi liyacwayiza ijwabu leso futhi umfundi uyafingqa ngokushesha,” kubika uProfesa Tóth.
Ingabe ihhashi lingaphila lingaboni ngokuphelele?
Ukuthi ihhashi liyakwamukela yini ubumpumputhe balo kungumuntu ngamunye. Kuphinde kuncike ekutheni ukuqhubekela phambili ekuqedeni ubumpumputhe bekucashile noma kubi kakhulu nokuthi kungenzeka yini ukukhulisa izimo zezindlu. Amahhashi angaboni ngakolunye uhlangothi abhekana kahle nokulinganiselwa ezimweni eziningi.
Ungakwazi yini ukugibela ihhashi eliyimpumputhe?
Izingane zingayigibela kanye nabantu abadala. Kunamahhashi amaningi ayizimpumputhe ohlangothini olulodwa aphumelelayo emdlalweni, futhi ngisho nangaphezulu aletha injabulo enkulu empilweni yabanikazi bawo njengabalingani bokungcebeleka.
Ihhashi lizamula nini?
Amahhashi awamane azamula lapho ekhathele noma lapho ehamba ekuseni. “Ukucindezeleka, ukuhlangana namanye amahhashi, noma izizathu ezingokomzimba ezinjengobuhlungu nakho kungase kubangele ukuzamula,” kusho umcwaningi wokuziphatha uDkt. Carole Fureix wase-University of Plymouth eNgilandi.
