Underwater camouflage is the set of methods of achieving crypsis—avoidance of observation—that allows otherwise visible aquatic organisms to remain unnoticed by other organisms such as predators or prey. Camouflage in large bodies of water differs markedly from camouflage on land. The environment is essentially the same on all sides.
In the sea, counter-illumination is one of three dominant methods of underwater camouflage, the other two being transparency and silvering. [1] Among marine animals, especially crustaceans , cephalopods , and fish , counter-illumination camouflage occurs where bioluminescent light from photophores on an organism 's ventral surface is matched to ...
For example, countershading is very common among land animals, but not for military camouflage. The dominant camouflage methods on land are countershading and disruptive coloration, supported by less frequent usage of many other methods. [4] The dominant camouflage methods in the open ocean are transparency, [5] reflection, and ...
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle ...
Photophores on fish are used for attracting food or for camouflage from predators by counter-illumination. [ citation needed ] Photophores are found on some cephalopods including the firefly squid , which can create impressive light displays, as well as numerous other deep sea organisms, such as the pocket shark Mollisquama mississippiensis and ...
Thayer's 1902 patent application. He failed to convince the US Navy. The English zoologist Edward Bagnall Poulton, author of The Colours of Animals (1890) discovered the countershading of various insects, including the pupa or chrysalis of the purple emperor butterfly, Apatura iris, [2] the caterpillar larvae of the brimstone moth, Opisthograptis luteolata [a] and of the peppered moth, Biston ...
Just like their sister branches on the ground, air forces around the world constantly seek to change and improve the camouflages they use. And like all other examples of camouflage, aircraft ...
