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:
“In the works of man, everything is as poor as its author; vision is confined, means are limited, scope is restricted, movements are labored, and results are humdrum.”
—Joseph De Maistre (1753–1821)
“You had such a vision of the street
As the street hardly understands;
Sitting along the bed’s edge, where
You curled the papers from your hair,
Or clasped the yellow soles of feet
In the palms of both soiled hands.”
—T.S. (Thomas Stearns)
“Would not some lightning flash of vision sear people’s consciousness into life again? What was the good of stopping the war if armies continued?”
—John Dos Passos (1896–1970)
