Biological Sunscreens Tune Polychromatic Ultraviolet Vision in Mantis Shrimp
VIDEO ABSTRACT Stomatopod crustaceans, or mantis shrimp, are renowned for their complex visual systems. Their array of 16 types of photoreceptors provides complex color reception, as well as linear and circular polarization sensitivity [1-6]. The least-understood components of their retina are the UV receptors, of which there are up to six distinct, narrowly tuned spectral types [4]. Here we sh...
متن کاملFiltering and polychromatic vision in mantis shrimps: themes in visible and ultraviolet vision.
Stomatopod crustaceans have the most complex and diverse assortment of retinal photoreceptors of any animals, with 16 functional classes. The receptor classes are subdivided into sets responsible for ultraviolet vision, spatial vision, colour vision and polarization vision. Many of these receptor classes are spectrally tuned by filtering pigments located in photoreceptors or overlying optical e...
متن کاملUltraviolet Photor~~~ptio~ in Mantis Shrimp
An UV-sensitive class of photoreceptors exists in all regions of the retinas of mantis shrimps. UV photosensitivity apparently resides in rhabdomeres of the eighth retinular cell (RS) that lies atop each rhabdom; and in ommatidia where the Rg rhabdomere consists of microvilli parallel in a single direction, ~nsiti~~ is maximal when the e-vector of plainly light is parallel to the mi~ro~Ui, Spec...
متن کاملA different form of color vision in mantis shrimp.
One of the most complex eyes in the animal kingdom can be found in species of stomatopod crustaceans (mantis shrimp), some of which have 12 different photoreceptor types, each sampling a narrow set of wavelengths ranging from deep ultraviolet to far red (300 to 720 nanometers). Functionally, this chromatic complexity has presented a mystery. Why use 12 color channels when three or four are suff...

both coloured and polarized light for communication. This often takes the form of a 'meral spread' in which the frontal appendages are opened to reveal species-specific coloured spots. The polarized light information is found mainly on the paddle-shaped flaps, parts of the antennae, on either side of the head. (As humans can't see polarized light, this information is depicted in the photograph ...
