I-sturgeon (Acipenser spp.)

I-sturgeon: le nhlanzi isibona kanjani isiyengo sakho

I-sturgeon: yimuphi umbala wesiyengo le nhlanzi ekwazi ngempela ukuwubona, ekujuleni kwakho nasemanzini akho. Izinhlobo zamakhoni ezingu-3, isiqongo ku-605 nm. Umehluko ohleliwe wemibala engu-54.

Acipenser spp.

Kukaliwe emndenini ofanayo

Alukho ukukala kwe-spectrum okwenziwe kulolu hlobo. Iziqongo zamakhoni zithathwe ezingeni lomndeni ku-i-sturgeon emhlophe (Acipenser transmontanus). Lokhu kuwukucabangela okungacijile kunokuthatha esihlotsheni sohlobo olulodwa; impendulo ebanzi ethi “yimuphi umkhawulo we-spectrum” iyathembeka, kanti ukuhleleka okucijile phakathi kwemibala eseduze akuthembeki. I-retina yalo isebenzisa i-chromophore ye-A2 (i-porphyropsin), edlulisela ukuzwela kwamagagasi amade kudlulele kobomvu kunalokho i-retina ye-A1 ebiyokunika khona. Izinhlanzi eziningi zamanzi amtoti ziyaguqula isilinganiso se-A1/A2 ngenkathi yonyaka nangokushisa, ngakho ukuzwela kwangempela kuyantweza unyaka wonke. Ama-sturgeon adla phansi, amehlo awo abuthuntu, ancike kakhulu ezindevini nasekuzweni ugesi.

Amarodi yiwo asebenzayo entathakusa, kuhwalala nasebusuku — okuyisikhathi abantu abaningi abadoba ngaso.

Imibuzo abantu abayibuzayo ngempela

I-sturgeon: ingabe le nhlanzi iyayibona imibala?

Yebo. Inezinhlobo zamakhoni ezingu-3, eziqonga ku-460 nm, 540 nm, 605 nm. Lokho kuyinika izinhlangothi zombala ezingu-2, uma umuntu enezimbili.

Ivelaphi le datha?

Alukho ukukala okwenziwe kulolu hlobo. Iziqongo zamakhoni zithathwe ezingeni lomndeni — kuthembekile ekusho ukuthi yimuphi umkhawulo we-spectrum, hhayi ekuhleleni okucijile phakathi kwemibala eseduze.
