“…In all of these domains, a predictive coding strategy is used. Note that this mechanism might be the basis for the higher polarization sensitivity values (7 -8) seen in the psychophysical [14] and electrophysiological [12,13] data compared with the physical measurements of dichroism in the cones. Next, we will compare these three datasets with the proposed retinal processing of e-vector information.…”

“…A second laser beam was passed through the receptor's long axis to measure axial dichroism and showed that MWS cones 1 had a dichroic ratio of 1.2 [20]. Although this is well below the polarization sensitivity of goldfish cones at 7 -8 [14], it was argued that the high polarization sensitivity is achieved by opponent interactions between polarization detectors [21]. Roberts & Needham [20] suggested that cone axial dichroism could be related to specializations in the outer segment of cone photoreceptors, such as disc membrane viscosity that aligns chromophores to predominately one axis of orientation and a slight tilting in the plane of absorbance of disc membrane.…”

“…Fishes such as engraulids [8,9], pomacentrids [10,11], salmonids [12,13], cyprinids [14] and cichlids [15] have polarization sensitivity and in some cases the potential to discriminate linearly polarized light. However, a clear link between the structure of the photoreceptors and polarization sensitivity is not as evident in vertebrates as in invertebrates.…”

In this review, we will discuss the recent literature on fish polarization vision and we will present a model on how the retina processes polarization signals. The model is based on a general retinalprocessing scheme and will be compared with the available electrophysiological data on polarization processing in the retina. The results of this model will help illustrate the functional significance of polarization vision for both feeding behaviour and navigation. First, we examine the linkage between structure and function in polarization vision in general.

“…Of these, double cones have been proposed to be involved in PL reception [65,66]. It is well established that internal reflections in the double cones in the fish retina form the basis of the PL sensors in fishes [65,[67][68][69][70]. Avian double cones, like the ones in fish, consist of a principal cone with an oil droplet and an accessory cone [71].…”

“…These fish have a UV-sensitive mechanism with polarization sensitivity to a vertically aligned e-vector and a green-and red-sensitive receptor mechanism with maximum polarization sensitivity to a horizontally aligned e-vector [2,67,68,82,83]. The intermediate blue-sensitive receptor mechanism is insensitive to PL.…”

Behavioural and physiological mechanisms of polarized light sensitivity in birds

Polarized light (PL) sensitivity is relatively well studied in a large number of invertebrates and some fish species, but in most other vertebrate classes, including birds, the behavioural and physiological mechanism of PL sensitivity remains one of the big mysteries in sensory biology. Many organisms use the skylight polarization pattern as part of a sun compass for orientation, navigation and in spatial orientation tasks. In birds, the available evidence for an involvement of the skylight polarization pattern in sun-compass orientation is very weak. Instead, cue-conflict and cue-calibration experiments have shown that the skylight polarization pattern near the horizon at sunrise and sunset provides birds with a seasonally and latitudinally independent compass calibration reference. Despite convincing evidence that birds use PL cues for orientation, direct experimental evidence for PL sensitivity is still lacking. Avian double cones have been proposed as putative PL receptors, but detailed anatomical and physiological evidence will be needed to conclusively describe the avian PL receptor. Intriguing parallels between the functional and physiological properties of PL reception and light-dependent magnetoreception could point to a common receptor system.

Light in the sea: The optical world of elasmobranchs

The evolution of elasmobranchs, which dates to at least Devonian time, reveals the early development of many of the characteristics present in living forms, including welldeveloped eyes. Although elasmobranchs occurred in both fresh and marine waters, modern species are common in most marine environments and rare in freshwater habitats. Consideration of visual adaptation in elasmobranchs, therefore, for the most part requires information of photic conditions in the sea. The classical studies of submarine light, e.g., attenuation due to scattering and absorption and its effect on the underwater spectrum, are reviewed. Most of these studies emphasize the static properties of underwater light and ignore changes in the time domain. They serve as a basis nevertheless to explain how the high absorption and the scattering of light by water molecules and included particles cause objects to become optically degraded over short distances. As a result, target detection is only useful over intermediate optical paths-meters rather than km. Elasmobranchs inhabit such different photic conditions that no single species can be considered representative. Thus, many forms possess a tapetum to enhance sensitivity a t low light levels, while species living a t depth have blue-shifted visual pigments. Most species, however, inhabit the upper photic regions of the sea where solar light during daylight is above photopic thresholds. Many of these species possess cones, presumably to enhance daytime vision. Consequently, emphasis is on light in the surface waters and the ecological problems of "seeing" targets in what is best described as I a "dynamic light field."
