Dynamic polarization vision in mantis shrimps
(Springer Nature Publishing AG, 2016-07-12)
Gaze stabilization is an almost ubiquitous animal behaviour, one that is required to see the world clearly and without blur. Stomatopods, however, only fix their eyes on scenes or objects of interest occasionally. Almost ...
Polarisation signals: a new currency for communication
(The Company of Biologists Ltd, 2019)
Most polarisation vision studies reveal elegant examples of how animals, mainly the invertebrates, use polarised light cues for navigation, course-control or habitat selection. Within the past two decades it has been ...
Out of the blue: the evolution of horizontally polarized signals in Haptosquilla (Crustacea, Stomatopoda, Protosquillidae)
(The Company of Biologists Ltd, 2014-07-09)
The polarization of light provides information that is used by many animals for a number of different visually guided behaviours. Several marine species, such as stomatopod crustaceans and cephalopod molluscs, communicate ...
The fish eye view: are cichlids conspicuous
(The Company of Biologists Ltd, 2010-06-11)
The extent of animal colouration is determined by an interplay between natural and sexual selection. Both forces probably shape colouration in the speciose, rock-dwelling cichlids of Lake Malawi. Sexual selection is thought ...
The Eyes Have It: Regulatory and Structural Changes Both Underlie Cichlid Visual Pigment Diversity
A major goal of evolutionary biology is to unravel the molecular genetic mechanisms that underlie functional diversification and adaptation. We investigated how changes in gene regulation and coding sequence contribute ...
A novel function for a carotenoid: astaxanthin used as a polarizer for visual signalling in a mantis shrimp
(The Company of Biologists Ltd, 2011-11-17)
Biological signals based on color patterns are well known, but some animals communicate by producing patterns of polarized light. Known biological polarizers are all based on physical interactions with light such as ...
High levels of reflectivity and pointillist structural color in fish, cephalopods, and beetles
(National Academy of Sciences, 2012-12-11)
Spectral tuning and the visual ecology of mantis shrimps
(The Royal Society, 2000-09-29)
The compound eyes of mantis shrimps (stomatopod crustaceans) include an unparalleled diversity of visual pigments and spectral receptor classes in retinas of each species. We compared the visual pigment and spectral receptor ...
Stomatopod photoreceptor spectral tuning as an adaptation for colour constancy in water
(Elsevier B.V., 1997-12)
Where colour is used in communication absolute judgement of signalling spectra is important, and failures of colour constancy may limit performance. Stomatopod crustaceans have unusual eyes in which the midband contains ...
