The Secret World of Shrimps: Polarisation Vision at Its Best

The ‘six-eyed’ stomatopod

Stomatopods (mantis shrimps) possess one of the most complex visual systems in the animal kingdom. Each eye is capable of monocular distance judgement, colour vision involving eight or more primary channels and polarisation vision. This involves a series of eye movements unique among the crustaceans. Furthermore, each eye usually acts almost entirely independently of the other. Colour, in parti...

Stomatopod eye structure and function: a review.

Stomatopods (mantis shrimps) possess apposition compound eyes that contain more photoreceptor types than any other animal described. This has been achieved by sub-dividing the eye into three morphologically discrete regions, a mid-band and two laterally placed hemispheres, and within the mid-band, making simple modifications to a commonly encountered crustacean photoreceptor pattern of eight ph...

Behavioural evidence for polarisation vision in stomatopods reveals a potential channel for communication

Polarisation sensitivity (PS) - the ability to detect the orientation of polarised light - occurs in a wide variety of invertebrates [1] [2] and vertebrates [3] [4] [5], many of which are marine species [1]. Of these, the crustacea are particularly well documented in terms of their structural [6] and neural [7] [8] adaptations for PS. The few behavioural studies conducted on crustaceans demonst...

Polarisation Vision of Crustaceans

The photoreceptor design of crustaceans, often containing regular arrays of intrinsically polarisation-sensitive microvilli, has had a profound influence on the visual biology of this subphylum. The land-based arthropods (insects and arachnids) also construct photoreceptors from ordered microvilli; however while in many species polarisation sensitivity results, a general overview of these group...
