I-wels catfish (Silurus glanis)

I-wels catfish: le nhlanzi isibona kanjani isiyengo sakho

I-wels catfish: yimuphi umbala wesiyengo le nhlanzi ekwazi ngempela ukuwubona, ekujuleni kwakho nasemanzini akho. Izinhlobo zamakhoni ezingu-2, isiqongo ku-535 nm. Umehluko ohleliwe wemibala engu-54.

Silurus glanis

Kukaliwe emndenini ofanayo

Alukho ukukala kwe-spectrum okwenziwe kulolu hlobo. Iziqongo zamakhoni zithathwe ezingeni lomndeni ku-i-channel catfish (Ictalurus punctatus) namanye ama-siluriform. 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-catfish anamehlo abuthuntu kakhulu futhi azingela kakhulu ngephunga, ngokunambitha nangomugqa waseceleni. Umbala uwuphawu oluncane ngempela kulolu hlobo, futhi lolu hlelo alufanele lufundwe njengoluphikisa lokho.

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

Imibuzo abantu abayibuzayo ngempela

I-wels catfish: ingabe le nhlanzi iyayibona imibala?

Yebo, kodwa kancane nje. Inezinhlobo zamakhoni ezingu-2, eziqonga ku-420 nm, 535 nm, ngakho inohlangothi olulodwa lombala lapho 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.
