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 (20/10)

Ukubona kuka-i-mantis shrimp kucace kangakanani?

Amehlo ayo ahlukanisa cishe ama-cycles angu-0.8 ngedigri (20/750 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-300°.

i-mantis shrimp ubona kanjani umuntu?

Amehlo ayo ahlukanisa cishe imijikelezo engu-0.8 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-75 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.

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).

i-mantis shrimp ibona kanjani ebumnyameni?

Isakhamuzi samahlelo koral; sivumelene namanzi angajulile futhi akhanyiswe kakhulu.

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.

Yini eyisipesheli ngokubona kuka-i-mantis shrimp?

Ibona i-UV nokukhanya okusabalaliswe okuyindingiliza
Amehlo anyakaza ngokwehlukene, ngalinye linokujula kwe-trinocular
Iskena umbala esikhundleni sokuwuqhathanisa
