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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Spectral perception in Octopus: A behavioral study

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.

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.

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).

Animal colour vision — behavioural tests and physiological concepts

TLDR
An overview of the methods used to study animal colour vision is given, and how quantitative modelling can suggest how photoreceptor signals are combined and compared to allow for the discrimination of biologically relevant stimuli is discussed.

Adaptation of a deep-sea cephalopod to the photic environment. Evidence for three visual pigments

TLDR
The small area of the ventral retina containing two visual pigments is thought to have a high and broad spectral sensitivity, which is useful for distinguishing the bioluminescence of squids of the same species in their environmental downwelling light.
