Active camouflage the surface, so when marine animals are seen from below, they appear darker than the background. Some species of cephalopod, such as the eye-flash squid and the firefly squid, produce light in photophores on their undersides to match the background. Bioluminescence is common among marine animals, so counterillumination may be widespread, though light has other functions, including attracting prey and signalling. Color change permits camouflage against different backgrounds. Many cephalopods including octopuses, cuttlefish, and squids, and some terrestrial amphibians and reptiles including chameleons and anoles can rapidly change color and pattern, though the major reasons for this include signalling, not
Lozenge camouflage Lozenge camouflage Lozenge camouflage was a military camouflage scheme in the form of patterned cloth or painted designs used by some aircraft of the Central Powers in the last two years of , primarily those of the Imperial German "Luftstreitkräfte". It takes its name from the repeated polygon shapes incorporated in the designs, many of which resembled lozenges.
