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.

متن کاملDevelopment of a bycatch reduction device (BRD) for shrimp beam trawl using flexible materials
This study aimed to design a bycatch reduction device (BRD) for shrimp beam trawl, which is manufactured by flexible materials to reduce bycatch for the gear in the South Sea of Korea. The model test was carried out to understand the shape of the gear in the water and to measure the variation of flow speed due to the BRD in a circulating water channel. Catches were compared between a shrimp b...

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...
