A brief account is given of the anatomy and fibre-optic-like light-guiding properties of rod-like elements in the eye photophores on the ventral surface of the eyeball of the Japanese firefly squid Watasenia scintillans. These light-guiding elements form a dominant proportion of the volume of the photophore (which is assumed to function in counter-illumination) and are aligned such that light from the bioluminescent core is directed in a cone downwards from the eye. A coplanar arrangement of…

Open water camouflage via ‘leaky’ light guides in the midwater squid Galiteuthis
Variation in the geometry of the photophore light guides reproduces the predicted variation in ocean radiance experienced by Galiteuthis, a midwater squid, and may reproduce the angular distribution of light at all positions in its habitat.
Bioluminescent signals spatially amplified by wavelength-specific diffusion through the shell of a marine snail
A remarkable bioluminescent adaptation in the marine snail Hinea brasiliana is described, which allows spatially amplified outward transmission of light communication signals from the snail, while allowing the animal to remain safely inside its hard protective shell.
The photophores of the squid family Cranchiidae (Cephalopoda: Oegopsida)
The comparative anatomy of the photophores supports the separation of the cranchiine and taoniine groups but the ultrastructural detail provides common links between the two.


Polarization Sensitivity in Compound Eyes
The compound eyes of insects and many other arthropods can detect a basic property of light which normally remains invisible to us: the plane of polarization. Arising by scattering in air and water,
Natural Polarized Light and Vision
Partial linear polarization is a prominent attribute of both scattered and reflected light in nature. Consequently sunlight in the atmosphere and hydrosphere produces substantial polarization
A Model for Enhancing the Visual InformationAvailable Under Low-Level Light Conditions:Multiple Contrast Channels Created by Stepwise Changesin Detector Parameters in the Banked Ventral Retina ofthe Firefly Squid
An hypothesis is proposed which accounts for the apparently conflicting evidence for the simultaneous presence of both systems of colour vision and polarization sensitivity in the firefly squids' deep sea habitat.
Assessing the Fitness of Visual Pigments for their Photic Environments
In the dictionary sense a pigment is a substance that is coloured to the human eye. Colour is so striking a sensation that it was once thought to be an attribute of the “coloured” substance itself.

It is probable that each type of bioluminescent signal in deep-sea organisms is but one factor in the suite of activities which make up a particular behavioural pattern.
Polarization contrast vision in Octopus.
Training octopuses to distinguish between targets on the basis of the presence or absence of a pattern produced by a 90 degrees polarization contrast within the target proved to provide information similar to that available from color vision and thus serve to enhance the detection and recognition of objects.
One type of photophore of the deep sea squid Pterygioteuthis microlampas was examined with the electron microscope and its fine structure described, and the similarity between photoproductive organelles and photoreceptive organelle is striking.

These adaptations include brightly coloured intrarhabdomal filters, apparent lateral filters and a photoreceptor tiering system unique to the crustacea which allow the spectrum of light available to stomatopods to be sampled over a broad spectral range by receptors with narrowly tuned sensitivities.
