They have 16 types of photoreceptor cells, 12 of which are specialized for different colors. The mantis shrimp are a widely distributed group consisting of more than 350 species; they vary in size from 1 to 30 centimetres (0.4 to 12 inches). It has to do with out-of-phase stereo imaging, which can best be explained by the effect you get when you put on 3-D glasses and watch a movie in 3-D. That’s circular polarization. Their front limbs are the most specialized, and some species use them as weapons. Ommatidia in Midband Rows 1-4 These ommatidia are much larger and more complex than those in the hemispheres. Using this … Stomatopods have an extraordinary visual system, incorporating independent movement of their eyes in all three degrees of rotational freedom. 2008).

PDF | Gaze stabilization is an almost ubiquitous animal behaviour, one that is required to see the world clearly and without blur. The Eye of the Peacock Mantis Shrimp The peacock mantis shrimp, found on Australia’s Great Barrier Reef, is equipped with the most complex eyesight in the animal kingdom. Each eye is divided into three regions for tracking motion, forms, depth, and color. In these species, the limbs become calcified which allows the shrimp use them as clubs. INTRODUCTION The mantis shrimp is a stomatopod known for its extraordinary eye sight. N2 - Almost all animals, regardless of the anatomy of the eyes, require some level of gaze stabilization in order to see the world clearly and without blur. With a Fiscal Year 2018 Peer Reviewed Cancer Research Program (PRCRP) Idea Award with Special Focus, Dr. Viktor Gruev developed a highly sensitive color-fluorescence endoscope, inspired by the mantis shrimp’s eye anatomy to detect cancerous and pre-cancerous tissue with high specificity and sensitivity in CRC and CAC patients. The mantis shrimp (which oddly is neither a mantis nor a shrimp, but a crustacean that resembles both) has arguably the most complicated visual system of any animal on Earth. Their bug-like eyes are equipped with a unique vision system, which discriminates between colours using a method never seen before.
