Ushaka osasibhakabhaka: le nhlanzi isibona kanjani isiyengo sakho
Ushaka osasibhakabhaka: yimuphi umbala wesiyengo le nhlanzi ekwazi ngempela ukuwubona, ekujuleni kwakho nasemanzini akho. Izinhlobo zamakhoni ezingu-1, isiqongo ku-532 nm. Umehluko ohleliwe wemibala engu-54.
Prionace glauca
Kukaliwe kulolu hlobo Le nhlanzi ayiyiboni imibala I-tapetum lucidum
Iziqongo zamakhoni ziwukukala okuqondile kwalolu hlobo. Okunye konke kule modeli — i-optics yamanzi, umehluko, ibanga lokubona — kusengukulinganisela, futhi akukho kukho okubikezela ukuthi inhlanzi izohlasela yini. Inayo i-tapetum lucidum — ungqimba olukhanyisayo ngemuva kwe-retina olucishe luphinde kabili ukubamba ukukhanya — yikho idla kahle kangaka entathakusa, kuhwalala nasemanzini anombala. UHart nabanye (2011) bathola uhlobo OLULODWA nje lwekhoni kuzo zonke izinhlobo zoshaka abazihlolayo. Cishe kuqinisekile ukuthi oshaka abayiboni imibala: babona isiteshi esisodwa sokukhanya. Ngakho lolu hlelo alukunikezi ukuhleleka kwemibala koshaka, ngoba akukho okungahlelwa — okubalulekile ukuthi isiyengo sikhanya noma simnyama kangakanani uma siqhathaniswa namanzi, hhayi okunye. Noma ubani okuthengisela isiyengo soshaka ngombala waso ukuthengisela umbala owubona wena kanti ushaka akawuboni.

| Irodi | 500 nm | A1 |
Amarodi yiwo asebenzayo entathakusa, kuhwalala nasebusuku — okuyisikhathi abantu abaningi abadoba ngaso.

Le nhlanzi ayiyiboni imibala — Inohlobo olulodwa lwekhoni, ngakho ibona isiteshi esisodwa sokukhanya. Ukuhleleka kwemibala akunamsebenzi kuyo — okubalulekile ukuthi isiyengo sakho sikhanya noma simnyama kangakanani uma siqhathaniswa namanzi.
Ngaphandle kombuthano wale modeli — Ngaphansi kwamamitha angaba ngu-60 izilinganiso zokukhanya kwemini kule modeli aziseqinisile. Funda lezi zinombolo njengezikhombisayo kuphela.
Thola le mibala
Emithathu ephume phambili, iseshwa ku-Amazon yakho. Ukuhleleka okungenhla kubalwa ngamanzi nangenhlanzi, ngaphambi kokuba lezi zixhumanisi zibe khona.

Lokho lawa manzi akudlulisayo
Ulwandle olucwebe kunazo zonke. Luluhlaza okujulile, futhi osasibhakabhaka ungena kakhulu.

Imibuzo abantu abayibuzayo ngempela
Ushaka osasibhakabhaka: ingabe le nhlanzi iyayibona imibala?
Inohlobo olulodwa lwekhoni, ngakho ibona isiteshi esisodwa sokukhanya. Ukuhleleka kwemibala akunamsebenzi kuyo — okubalulekile ukuthi isiyengo sakho sikhanya noma simnyama kangakanani uma siqhathaniswa namanzi.
Ivelaphi le datha?
I-microspectrophotometry eqondile, i-ERG noma ukuzwela kwe-spectrum okuhlolwe ngokuziphatha kwalolu hlobo.
