Indlela ezibona ngayo
i-mantis shrimp ibona kanjani umhlaba?
Kuze kube ama-receptor ayi-16 — ne-polarization
I-mantis shrimp iphethe okungenzeka abe ngamehlo ayinkimbinkimbi kunawo wonke emhlabeni: kuze kufike izigaba eziyishumi nesithupha zama-photoreceptor kweyethu emithathu, kanye nekhono lokubona ukukhanya okuyi-polarised. Okumangalisayo ukuthi ayiboni umbala ngokucolekile kunathi. Kunokuxuba izimpawu ezivela emakhonini ambalwa ngendlela ubuchopho bethu obwenza ngayo, i-detector ngayinye iskena ibhande elincane, okuvumela isilwane ukuthi sibone imibala ngokushesha ngaphandle kwe-arithmetic yengqondo enzima.
Umuntu ≈ 60 cpd (20/20)
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
Inombolo enkulu kunazo zonke yezinhlobo zama-receptor kunoma iyiphi isilwane esaziwayo, kusukela ku-UV ejulile kuya ku-obomvu okukude, kanye ne-polarization eqondile neyindingiliza; kodwa ukuhlukanisa kwayo umbala kuluhlaza (uhlelo oluskena, hhayi oluqhathanisayo).
Ama-photoreceptor
Kufinyelela ku-12-16 izinhlobo zama-photoreceptor + ukubona i-polarization
Iziqongo zokuzwela kwama-cone
- Iqoqo le-UV315 nm
- Iqoqo elibonakalayo500 nm
- Iqoqo lamaza amade700 nm
Ukubona ekukhanyeni okuncane
Isakhamuzi samahlelo koral; sivumelene namanzi angajulile futhi akhanyiswe kakhulu.
Uma kuqhathaniswa nokubona komuntu
Wena uqhathanisa izimpawu ezivela emakhonini amathathu ukuze wakhe izigidi zemibala. I-mantis shrimp iphatha kuze kufike izinhlobo eziyishumi nesithupha zama-receptor, ezisabalala kusukela ku-ultraviolet kuya kokubomvu okukude, kodwa, ngokumangalisayo, ihlukanisa imibala efanayo ngokuluvivi kunawe.
Izici eziphawulekayo
- Ibona i-UV nokukhanya okusabalaliswe okuyindingiliza
- Amehlo anyakaza ngokwehlukene, ngalinye linokujula kwe-trinocular
- Iskena umbala esikhundleni sokuwuqhathanisa
Imibuzo evame ukubuzwa
i-mantis shrimp ibona kanjani umhlaba?
I-mantis shrimp iphethe okungenzeka abe ngamehlo ayinkimbinkimbi kunawo wonke emhlabeni: kuze kufike izigaba eziyishumi nesithupha zama-photoreceptor kweyethu emithathu, kanye nekhono lokubona ukukhanya okuyi-polarised. Okumangalisayo ukuthi ayiboni umbala ngokucolekile kunathi.

Yimiphi imibala i-mantis shrimp engayibona?
Inombolo enkulu kunazo zonke yezinhlobo zama-receptor kunoma iyiphi isilwane esaziwayo, kusukela ku-UV ejulile kuya ku-obomvu okukude, kanye ne-polarization eqondile neyindingiliza; kodwa ukuhlukanisa kwayo umbala kuluhlaza (uhlelo oluskena, hhayi oluqhathanisayo). Kufinyelela ku-12-16 izinhlobo zama-photoreceptor + ukubona i-polarization
Ukubona kuka-i-mantis shrimp kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-2 ngedigri (20/600), kanti umuntu ufinyelela cishe ku-60 cpd (20/20). Ibanga layo lokubona lisabalala cishe ngo-300°.
i-mantis shrimp 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.
i-mantis shrimp ibona kanjani ebumnyameni?
Isakhamuzi samahlelo koral; sivumelene namanzi angajulile futhi akhanyiswe kakhulu.
Yini eyisipesheli ngokubona kuka-i-mantis shrimp?
Ibona i-UV nokukhanya okusabalaliswe okuyindingiliza. Amehlo anyakaza ngokwehlukene, ngalinye linokujula kwe-trinocular. Iskena umbala esikhundleni sokuwuqhathanisa. I-mantis shrimp iyilwane kuphela elaziwayo elithola ukukhanya okuyi-circularly polarised, into amehlo ethu angeke ayiqaphe nhlobo. Abacwaningi basola ukuthi bayisebenzisa njengesiteshi sokukhwela sangasese.
Ukubona kuka-i-mantis shrimp kuqhathaniswa kanjani nokomuntu?
Wena uqhathanisa izimpawu ezivela emakhonini amathathu ukuze wakhe izigidi zemibala. I-mantis shrimp iphatha kuze kufike izinhlobo eziyishumi nesithupha zama-receptor, ezisabalala kusukela ku-ultraviolet kuya kokubomvu okukude, kodwa, ngokumangalisayo, ihlukanisa imibala efanayo ngokuluvivi kunawe.
