We tested color perception based upon a robust behavioral response in which cuttlefish (Sepia officinalis) respond to visual stimuli (a black and white checkerboard) with a quantifiable, neurally controlled motor response (a body pattern). In the first experiment, we created 16 checkerboard substrates in which 16 grey shades (from white to black) were paired with one green shade (matched to the maximum absorption wavelength of S. officinalis' sole visual pigment, 492 nm), assuming that one of… Expand
Testing the Optomotor Response in Sepia bandensis
TLDR
Visual function of the dwarf cuttlefish (Sepia bandensis), which differs from S. officinalis in habitat, geographic range, and size, is examined to indicate that S. bandensis has poorer visual acuity than S. Officinalis, and therefore, may be less able to resolve fine details in the environment. Expand
Disruptive coloration in cuttlefish: a visual perception mechanism that regulates ontogenetic adjustment of skin patterning
TLDR
The results indicate that cuttlefish are solving a visual scaling problem of camouflage presumably without visual confirmation of the size of their own skin component. Expand
Maturation of polarization and luminance contrast sensitivities in cuttlefish (Sepia officinalis)
TLDR
The results suggest that polarization is not a simple modulation of luminance information, but rather that it is processed as a distinct channel of visual information that seems to help in prey detection. Expand
Perception of visual texture and the expression of disruptive camouflage by the cuttlefish, Sepia officinalis
TLDR
Cuttlefish probably have edge detectors that control the expression of disruptive pattern, and it seems probable that cuttlefish display disruptive camouflage when there are edges in the visual background caused by discrete objects such as pebbles. Expand
Crown-of-thorns starfish have true image forming vision
TLDR
The observation that crown-of-thorns starfish respond to black-and-white shapes on a mid-intensity grey background is the first direct proof of true spatial vision in starfish and in the phylum Echinodermata. Expand
Dark scene elements strongly influence cuttlefish camouflage responses in visually cluttered environments
TLDR
The main finding is that darker‐than‐average texels (i.e., texels of negative contrast polarity) predominate in controlling cuttlefish pattern responses in the context of cluttered substrates. Expand
Depth perception: cuttlefish (Sepia officinalis) respond to visual texture density gradients
TLDR
It is demonstrated that cuttlefish are responsive to visual cues involving texture gradients, and it is suggested that these cephalopods were responding to the depth illusion created by the texture density gradient. Expand
A review of cuttlefish camouflage and object recognition and evidence for depth perception
TLDR
It is argued that the visual strategy cuttlefish use to select camouflage is fundamentally similar to human object recognition. Expand
A review of visual perception mechanisms that regulate rapid adaptive camouflage in cuttlefish
TLDR
This sensorimotor approach of studying cuttlefish camouflage provides unique insights into the mechanisms of visual perception in an invertebrate image-forming eye. Expand
Disruptive coloration elicited on controlled natural substrates in cuttlefish, Sepia officinalis
TLDR
This study assembled a natural rock substrate with those features that are thought to elicit disruptive coloration in cuttlefish and found that the results support this prediction, and that there is a strong correlation between fine details of the visual background properties and the resultant body pattern shown by the Cuttlefish.

Ontogenetic changes in the visual acuity of Sepia officinalis measured using the optomotor response
TLDR
A significant effect of both body size and light intensity is found; larger animals had greater visual acuity, while individuals of all size classes discriminated more detail at higher light intensities. Expand
Cuttlefish camouflage: visual perception of size, contrast and number of white squares on artificial checkerboard substrata initiates disruptive coloration.
TLDR
It is demonstrated that the size, contrast and number of white objects in the surrounding substratum influence the production and expression of disruptive skin patterns in young cuttlefish. Expand
Disruptive Body Patterning of Cuttlefish (Sepia officinalis) Requires Visual Information Regarding Edges and Contrast of Objects in Natural Substrate Backgrounds
TLDR
The results show that, to evoke disruptive coloration in cuttlefish, visual information about the edges and contrast of objects within natural substrate backgrounds is required. Expand
Some evidence for colour-blindness in Octopus.
TLDR
The absence of visual response to moving coloured stripes suggests that the failure of octopuses to learn a hue discrimination may be the result of an inherent incapacity at the retinal level, strongly suggesting that O. vulgaris is colour-blind. Expand
Evidence that Octopus is Colour Blind
1.Six octopuses were trained on a series of visual discrimination tasks where the discriminanda were presented simultaneously, and where different tasks alternated in a single training session. 2.AllExpand

TLDR
It was concluded that this octopus lacks color vision by using lights differing in wavelength as training stimuli and comparing the results with those of shape discrimination training experiments. Expand
A wavelength discrimination function for the hummingbirdArchilochus alexandri
TLDR
Free-flying black-chinned hummingbirds at a site in southeastern Arizona were attracted to artificial feeders displaying narrow spectral bands of light, consistent with a growing body of evidence suggesting that the color space of birds may be more than three dimensional. Expand
STRUCTURAL BASIS FOR WAVELENGTH DISCRIMINATION IN THE BANKED RETINA OF THE FIREFLY SQUID WATASENIA SCINTILLANS
TLDR
It is proposed that the A2-based visual pigment is contained in the pink-layer cells and that the 4-hydroxyretinal-basedvisual pigment iscontained in the three types of yellow- layer cells. Expand
Cuttlefish cue visually on area--not shape or aspect ratio--of light objects in the substrate to produce disruptive body patterns for camouflage.
TLDR
This study examines the shapes and aspect ratios of white objects on black backgrounds that lead cuttlefish to show disruptive coloration and develops a non-invasive assay that monitors motor output resulting from different visual inputs (computer-generated artificial substrates). Expand
On the three visual pigments in the retina of the firefly squid, Watasenia scintillans
TLDR
The extraction and analysis of retinoids to determine the origin of 3-dehydroretinal and 4-Hydroxyretinal in the mature squid showed only a trace amount of 4-hydroxyretinol in the eggs, and similar analysis of other cephalopods collected near Japan showed the absence of A2 or A4 pigment in their eyes.
