Lagoon Triggerfish - Vision

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.

  • Lagoon Triggerfish live on the flat areas of the reef.

  • Lagoon Triggerfish swimming around the reef of Fihalhohi, the Maldives.

Famous quotes containing the word vision:

    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)

    With the supermarket as our temple and the singing commercial as our litany, are we likely to fire the world with an irresistible vision of America’s exalted purpose and inspiring way of life?
    Adlai Stevenson (1900–1965)

    To stroll is a science, it is the gastronomy of the eye. To walk is to vegetate, to stroll is to live.... To stroll is to enjoy, it is to assume a mind-set, it is to admire the sublime pictures of unhappiness, of love, of joy, of graceful or grotesque portraits; it is to plunge one’s vision to the depths of a thousand existences: young, it is to desire everything; old, it is to live the life of the young, to marry their passions.
    HonorĂ© De Balzac (1799–1850)
