Formatted abstract
Coleoid cephalopods (octopus, cuttlefish and squid) potentially possess polarization sensitivity (PS) based on photoreceptor
structure, but this idea has rarely been tested behaviourally. Here, we use a polarized, striped optokinetic stimulus to demonstrate
PS in the striped pyjama squid, Sepioloidea lineolata. This species displayed strong, consistent optokinetic nystagmic eye
movements in response to a drum with stripes producing e-vectors set to 0deg, 45deg, 90deg and 135deg that would only be
visible to an animal with PS. This is the first behavioural demonstration of a polarized optokinetic response in any species of
cephalopod. This species, which typically sits beneath the substrate surface looking upwards for potential predators and prey,
possesses a dorsally shifted horizontal pupil slit. Accordingly, it was found to possess a horizontal strip of high-density
photoreceptors shifted ventrally in the retina, suggesting modifications such as a change in sensitivity or resolution to the dorsal
visual field. © 2010. Published by The Company of Biologists Ltd.
