Cephalopod dynamic camouflage
Everyone knows what camouflage is and how it works. And many people (some scientists included) think chameleons are the masters of color change. Wrong on both counts. In this primer, I provide an overview of recent work on the mechanisms and principles of rapid adaptive camouflage of cephalopods — octopus, cuttlefish and squids. These strange but capable marine invertebrates can camouflage them...
متن کاملCephalopod dynamic camouflage: bridging the continuum between background matching and disruptive coloration.
Individual cuttlefish, octopus and squid have the versatile capability to use body patterns for background matching and disruptive coloration. We define--qualitatively and quantitatively--the chief characteristics of the three major body pattern types used for camouflage by cephalopods: uniform and mottle patterns for background matching, and disruptive patterns that primarily enhance disruptiv...
متن کاملReconfigurable infrared camouflage coatings from a cephalopod protein.
In nature, cephalopods employ unique dynamic camouflage mechanisms. Herein, we draw inspiration from self-assembled structures found in cephalopods to fabricate tunable biomimetic camouflage coatings. The reflectance of these coatings is dynamically modulated between the visible and infrared regions of the electromagnetic spectrum in situ. Our studies represent a crucial step towards reconfigur...
متن کاملAdaptive optoelectronic camouflage systems with designs inspired by cephalopod skins.
Octopus, squid, cuttlefish, and other cephalopods exhibit exceptional capabilities for visually adapting to or differentiating from the coloration and texture of their surroundings, for the purpose of concealment, communication, predation, and reproduction. Long-standing interest in and emerging understanding of the underlying ultrastructure, physiological control, and photonic interactions has...
متن کاملModular organization of dynamic camouflage body patterning in
Cephalopods have the most sophisticated dynamic skin coloration for rapidly camouflage in nature. Previous studies have suggested that the pair of optic lobes located bilaterally in their brain plays a key role in controlling the expansion of chromatophores for generating diverse body patterns. However, the functional organization of the optic lobes and their neural control of various body patt...
