Indlela ezibona ngayo

i-dragonfish ibona kanjani umhlaba?

Isibhamu esiyimfihlo esibona obomvu obukude

Ebumnyameni obucindezelayo bolwandle olujulile, izilwane eziningi zibona okuluhlaza okwesibhakabhaka kuphela, umbala wokugcina ofinyelela lapho ekujuleni. I-dragonfish iwukuhluka okungavamile onemfihlo ebulalayo: ezinye izinhlobo zikhiqiza futhi zibone ukukhanya okubomvu, i-wavelength yangasese inyamazane yazo eyimpumputhe kuyo. Ngokusebenzayo iphethe isikoprofu somdubuli, ikhanyisa izisulu ngombala ezingakaze zilubone luza.

Ukucaca kokubona2 cpd · 20/300 (est.)

Ibanga lokubona180°

Umuntu ≈ 60 cpd (20/10)

Ukubona kuka-i-dragonfish kucace kangakanani?

Amehlo ayo ahlukanisa cishe ama-cycles angu-2 ngedigri (20/300 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-180°.

i-dragonfish ubona kanjani umuntu?

Amehlo ayo ahlukanisa cishe imijikelezo engu-2 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-30 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.

Yimiphi imibala i-dragonfish engayibona?

Ukubona okuyi-monochromatic ngokuyisisekelo kokuluhlaza sasibhakabhaka ebumnyameni, kanye nesiteshi esiyimfihlo sobomvu obukude esisebenzisa ukukhanyisa izinyamazane ngaphandle kokubonwa.

Ama-photoreceptor

Ibuswa amaseli e-rod futhi ivumelene noluhlaza sasibhakabhaka; ezinye izinhlobo zithola nobomvu obukude

Iziqongo zokuzwela kwama-cone

Esiyinhloko (oluhlaza sasibhakabhaka-luhlaza)530 nm
Obomvu obukude (esikhethekile)705 nm

i-dragonfish ibona kanjani ebumnyameni?

Okukhulu: ivumelene nendawo yasezinzulwini.

Ukubona kuka-i-dragonfish kuqhathaniswa kanjani nokomuntu?

Imininingwane ye-dragonfish mibi, mhlawumbe ku-20/300 kune-20/20 yakho, futhi umhlaba wayo empeleni uwuluhlaza olulodwa oluvivi. Naphezu kwakho konke, ilungiselelwe kahle kakhulu ubumnyama lapho wena ubungabona lutho, futhi ezinhlobo ezimbalwa zisebenzisa isiteshi esibomvu esizimele.

Yini eyisipesheli ngokubona kuka-i-dragonfish?

Ikhipha futhi ibone ukukhanya obomvu obukude okungabonakali ezinyamazaneni
Iphila cishe ebumnyameni
Amaseli e-rod avumelene noluhlaza sasibhakabhaka
