I-peacock bass: le nhlanzi isibona kanjani isiyengo sakho
I-peacock bass: yimuphi umbala wesiyengo le nhlanzi ekwazi ngempela ukuwubona, ekujuleni kwakho nasemanzini akho. Izinhlobo zamakhoni ezingu-3, isiqongo ku-600 nm. Umehluko ohleliwe wemibala engu-54.
Cichla spp.
Kukaliwe emndenini ofanayo
Alukho ukukala kwe-spectrum okwenziwe kulolu hlobo. Iziqongo zamakhoni zithathwe ezingeni lomndeni ku-amanye ama-cichlid ase-Neotropic. 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-peacock bass ahlala emanzini amnyama anetanini lapho ukukhanya okusasibhakabhaka kuphela kungakahambi namasentimitha, ngakho ukuqhutshelwa emagagasini amade okucatshangelwe lapha kunesizathu esiqinile sendawo ehlala kuyo — kodwa kungukucabangela, akukhona ukukala.
Ukuzwela kwe-spectrum
| Iziqongo zamakhoni | λmax | I-chromophore |
|---|---|---|
| Obufushane | 460 nm | A2 |
| Obuphakathi | 530 nm | A2 |
| Obude | 600 nm | A2 |
| Irodi | 520 nm | A2 |
Amarodi yiwo asebenzayo entathakusa, kuhwalala nasebusuku — okuyisikhathi abantu abaningi abadoba ngaso.

Imibuzo abantu abayibuzayo ngempela
I-peacock bass: ingabe le nhlanzi iyayibona imibala?
Yebo. Inezinhlobo zamakhoni ezingu-3, eziqonga ku-460 nm, 530 nm, 600 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.
