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:
“Deep in the human heart
The fire of justice burns;
A vision of a world renewed
Through radical concern.”
—William L. Wallace (20th century)
“I’ve been cursed for delving into the mysteries of life. Perhaps death is sacred, and I’ve profaned it. Oh, what a wonderful vision it was. I dreamed of being the first to give to the world the secret that God is so jealous of, the formula for life. Think of the power, to create a man. And I did, I did it, I created a man. And who knows, in time I could have trained him to do my will. I could have bred a race, I might even have found the secret of eternal life.”
—William Hurlbut (1883–?)
“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)
