Indlela ezibona ngayo
i-zebrafish ibona kanjani umhlaba?
Iziteshi ezine zamakhoni kanye nokubuka okuseduze kwepanoramic
I-zebrafish inezigaba ezine ze-cone—i-ultraviolet, eluhlaza okwesibhakabhaka, eluhlaza nokubomvu—kwi-retina eyakhelwe amanzi agqamile angashoni. Amehlo ayo aseceleni ahlola ama-degree angu-339 emzimbeni wonke, kuyilapho ukuhlolwa kokuziphatha kwabantu abadala kubeka ukuqonda kwendawo emijikelezweni engu-0.56 kuya ku-0.58 kuphela ngedigri ngayinye. Imininingwane emihle iyafiphala, kodwa umbala kanye nokumbozwa okuseduze kwepanoramic kuhlala kumaphakathi.

Ukuqhathanisa imibala
How each colour shifts when seen through this animal's eyes, using the same colour model as the app. Tones a screen can't emit (such as ultraviolet) are shown as an approximation.
Ukubona umbala
Amakilasi ama-cone amane aphakela amasekhethi e-retina aphikisana nombala. Ezibungwini, ishaneli ye-ultraviolet endaweni engaphezulu yangaphambili ikhethekile ukuze ibone inyamazane ekhanyayo e-ultraviolet.
Ama-photoreceptor
I-Tetrachromat ene-ultraviolet, blue, green and red cones
Iziqongo zokuzwela kwama-cone
- I-Ultraviolet362 nm
- I-Short-wave eluhlaza okwesibhakabhaka415 nm
- Igagasi elimaphakathi eliluhlaza480 nm
- Igagasi elide elibomvu570 nm
Ukubona ekukhanyeni okuncane
I-retina iqukethe izinti nama-cones. Kumaseli abantu abadala angawodwa, izimpendulo zenduku zazicishe zibe izikhathi ezingama-40 kuya kwezingu-220 ezizwela kakhulu kunezimpendulo zekhoni; umbala ngokuyinhloko uwumsebenzi wokukhanya okukhanyayo.
Uma kuqhathaniswa nokubona komuntu
Abantu basebenzisa izigaba ezintathu zamakhoni futhi ababoni i-ultraviolet; I-zebrafish isebenzisa ezine futhi ikhava amadigri angu-339 kunokuba cishe u-200. Isikrini se-RGB singasebenzisa kuphela umbala ongamanga kanye nokufiphala okulinganiselwe ukuze kukhulunywe lowo mehluko, singalokothi sikhiqize kabusha ngokoqobo.
Izici eziphawulekayo
- Amakilasi ama-cone amane, kufaka phakathi imisebe ye-ultraviolet
- Ukumbozwa kwabantu abadala okungu-339-degree enomkhakha wezimpumputhe wangemuva ongu-21-degree
- Fronto-dorsal acute zone; ama-larval ultraviolet cones asebenza ngokukhethekile ekubambeni inyamazane
Imibuzo evame ukubuzwa
i-zebrafish ibona kanjani umhlaba?
I-zebrafish inezigaba ezine ze-cone—i-ultraviolet, eluhlaza okwesibhakabhaka, eluhlaza nokubomvu—kwi-retina eyakhelwe amanzi agqamile angashoni. Amehlo ayo aseceleni ahlola ama-degree angu-339 emzimbeni wonke, kuyilapho ukuhlolwa kokuziphatha kwabantu abadala kubeka ukuqonda kwendawo emijikelezweni engu-0.56 kuya ku-0.58 kuphela ngedigri ngayinye. Imininingwane emihle iyafiphala, kodwa umbala kanye nokumbozwa okuseduze kwepanoramic kuhlala kumaphakathi. Amakilasi ama-cone amane aphakela amasekhethi e-retina aphikisana nombala. Ezibungwini, ishaneli ye-ultraviolet endaweni engaphezulu yangaphambili ikhethekile ukuze ibone inyamazane ekhanyayo e-ultraviolet.
Yimiphi imibala i-zebrafish engayibona?
Amakilasi ama-cone amane aphakela amasekhethi e-retina aphikisana nombala. Ezibungwini, ishaneli ye-ultraviolet endaweni engaphezulu yangaphambili ikhethekile ukuze ibone inyamazane ekhanyayo e-ultraviolet. I-Tetrachromat ene-ultraviolet, blue, green and red cones
Ukubona kuka-i-zebrafish kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-0.57 ngedigri (No direct Snellen equivalent; 0.56–0.58 cpd behavioural OKR), kanti umuntu ufinyelela cishe ku-60 cpd (20/20). Ibanga layo lokubona lisabalala cishe ngo-339°.
i-zebrafish ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-0.57 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-105 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
i-zebrafish ibona kanjani ebumnyameni?
I-retina iqukethe izinti nama-cones. Kumaseli abantu abadala angawodwa, izimpendulo zenduku zazicishe zibe izikhathi ezingama-40 kuya kwezingu-220 ezizwela kakhulu kunezimpendulo zekhoni; umbala ngokuyinhloko uwumsebenzi wokukhanya okukhanyayo.
Yini eyisipesheli ngokubona kuka-i-zebrafish?
Amakilasi ama-cone amane, kufaka phakathi imisebe ye-ultraviolet. Ukumbozwa kwabantu abadala okungu-339-degree enomkhakha wezimpumputhe wangemuva ongu-21-degree. Fronto-dorsal acute zone; ama-larval ultraviolet cones asebenza ngokukhethekile ekubambeni inyamazane. Ezibungwini, izigaxa ze-ultraviolet ezikuyi-retina engaphezulu engaphambili zibamba ama-photon e-ultraviolet amaningi ngokuphindwe izikhathi eziyishumi kunamanye ama-ultraviolet cones, okusiza izinhlanzi zithole inyamazane encane ekhanya nge-ultraviolet. Lobu buchwepheshe buqondene nesigaba sempilo.
Ukubona kuka-i-zebrafish kuqhathaniswa kanjani nokomuntu?
Abantu basebenzisa izigaba ezintathu zamakhoni futhi ababoni i-ultraviolet; I-zebrafish isebenzisa ezine futhi ikhava amadigri angu-339 kunokuba cishe u-200. Isikrini se-RGB singasebenzisa kuphela umbala ongamanga kanye nokufiphala okulinganiselwe ukuze kukhulunywe lowo mehluko, singalokothi sikhiqize kabusha ngokoqobo.
