Vision
This species has one type of single cone (SC), with visual pigment peaking in sensitivity at 413 nm (S), and a double cone with different visual pigments in each member peaking at 480 nm (M) and 530 nm (L) respectively. Behavioural research has provided evidence that individual members of the double cones can act as independent channels of colour information, aiding in understanding double cone function. This research suggests the species has trichromatic vision, like humans.

Famous quotes containing the word vision:
“Every civilization when it loses its inner vision and its cleaner energy, falls into a new sort of sordidness, more vast and more stupendous than the old savage sort. An Augean stable of metallic filth.”
—D.H. (David Herbert)
“The liveliness of literature lies in its exceptionality, in being the individual, idiosyncratic vision of one human being, in which, to our delight and great surprise, we may find our own vision reflected.”
—Salman Rushdie (b. 1947)
“The difference between human vision and the image perceived by the faceted eye of an insect may be compared with the difference between a half-tone block made with the very finest screen and the corresponding picture as represented by the very coarse screening used in common newspaper pictorial reproduction. The same comparison holds good between the way Gogol saw things and the way average readers and average writers see things.”
—Vladimir Nabokov (1899–1977)
