Odontodactylus scyllarus,Peacock Mantis Shrimp

Chinese name:孔雀螳螂虾、蝉形齿指虾蛄、 纹华青龙虾

O. scyllarus is one of the larger, more colourful mantis shrimps commonly seen, ranging in size from 3 to 18 cm (1.2 to 7.1 in).[1] They are primarily green with orange legs and leopard-like spots on the anterior carapace.

Their ability to see circularly polarised light has led to studies to determine if the mechanisms by which their eyes operate can be replicated for use in reading CDs and similar optical information-storage devices.
