Summary: | We describe "accessory corner cones" contained in the retinas of sevenspecies of Antarctic adult nototheniid fishes (Nototheniidae, Perciformes)and suggest, on the basis of morphology, that they are UV-sensitivephotoreceptors. The potential significance of the presence of UV-sensitivityin Antarctic fish is that it might increase foraging efficiency by enhancingthe contrast of important prey. Krill (Euphausia superba), for example, areprobably silhouetted against UV-background space light during the Antarcticsummer. |
