“…Although faster than Nautilus, this is still considerably slower than many other animals, and the speed of the pupil response in coleoid cephalopods is therefore generally quoted as being much less rapid than that of, for example, mammals (e.g. Hurley et al, 1978;Messenger, 1981). However, the temporal resolution of this earlier work was poor as digital video technology was not available.…”

“…Similarly, chickens give a much larger response to the presentation of a red stimulus (possibly indicating blood) than they do to a simple change in light level (Barbur et al, 2002). The pupil of cephalopods also dilates when they are 'aroused' during fighting, mating or viewing food (Beer, 1897;Bateson, 1890;Packard and Sanders, 1971;Muntz, 1977;Wells, 1966Wells, , 1978Hurley et al, 1978;Messenger, 1981).…”

This paper provides the first detailed description of the time courses of light-evoked pupillary constriction for two species of cephalopods, Sepia officinalis (a cuttlefish) and Eledone cirrhosa (an octopus). The responses are much faster than hitherto reported, full contraction in Sepia taking less than 1·s, indicating it is among the most rapid pupillary responses in the animal kingdom. We also describe the dependence of the degree of pupil constriction on the level of ambient illumination and show considerable variability between animals. Furthermore, both Sepia and Eledone lack a consensual light-evoked pupil response. Pupil dilation following darkness in Sepia is shown to be very variable, often occurring within a second but at other times taking considerably longer. This may be the result of extensive light-independent variations in pupil diameter in low levels of illumination.

“…Animals, however, are known to use polarised light for a range of tasks, including the detection of bodies of water by airborne insects using surface-reflected polarised light (Schwind, 1983;Schwind, 1991;Kriska et al, 1998;Horváth et al, 2011), intra-specific communication with inbuilt polarised body patterns Chiou et al, 2008;Chiou et al, 2011), and navigation and orientation using the pattern of celestial polarised light (von Frisch, 1949;Wehner, 1976;Dacke et al, 2003;Weir and Dickinson, 2012). Some animals, such as cephalopods, have apparently evolved an acute polarisation sense as a substitute for colour vision (Moody and Parriss, 1961;Messenger, 1981;Marshall et al, 1999;Temple et al, 2012). Much is now known about the structures involved in invertebrate polarisation vision (reviewed by Wehner and Labhart, 2006).…”

“…Ability to form an image also varies among molluscs. Coleoid cephalopods are probably best known for their excellent perception of images and ability to visual discriminate (review in Messenger 1981); perhaps lesser known is the wide degree of visual capabilities found among gastropods (Messenger 1981, Zieger andMeyerRochow 2008). Finally, it should be noted that mollusc eyes may also be important for migratory behaviors in pelagic and benthic species (Hamilton 1985).…”

Several invertebrate systems have been developed to study various aspects of the eye and eye disease including Drosophila, Planaria, Platynereis, and most recently, the cubozoan jellyfish Tripedalia; however, molluscs, the second largest metazoan phylum, so far have been underrepresented in eye research. This is surprising as mollusc systems offer opportunities to study visual processes that may be altered by disease, vision physiology, development of the visual system, behavior, and evolution. Malacologists have labored for over a century as morphologists, systematists, physiologists, and ecologists in order to understand the structural and functional diversity in molluscs at all levels of biological organization. Yet, malacologists have had little opportunity to interact with researchers whose interests are restricted to the biology and development of eyes as model systems as they tend not to publish in the same journals or attend the same meetings. In an effort to highlight the advantages of molluscan eyes as a model system and encourage greater collaboration among researchers, I provide an overview of molluscan eye research from these two perspectives: eye researchers whose interests involve the development, physiology, and disease of the eye and malacologists who study the complete organism in its natural environment. I discuss the developmental and genetic information available for molluscan eyes and the need to place this work in an evolutionary perspective. Finally, I discuss how synergy between these two groups will advance eye research, broaden research in both fields, and aid in developing new molluscan models for eye research.
