Camouflage the peacock flounder, squid and octopus actively change their skin patterns and colours using special chromatophore cells to resemble their current background, or, as in most chameleons, for signalling. However, Smith's dwarf chameleon does use active colour change for camouflage. Each chromatophore contains pigment of only one colour. In fish and frogs, colour change is mediated by the type of chromatophores known as melanophores that contain dark pigment. A melanophore is star-shaped; it contains many small pigmented organelles which can be dispersed throughout the cell, or aggregated near its centre. When the pigmented organelles are dispersed, the cell makes a
Underwater camouflage one of these methods to camouflage themselves. Camouflage in relatively shallow waters is more like terrestrial camouflage, where additional methods are used by animals in many different groups. These methods of camouflage are described in turn below. Transparency is common, even dominant, in animals of the open sea, especially those that live in relatively shallow waters. It is found in plankton of many species, as well as larger animals such as jellyfish, salps (floating tunicates), and comb jellies. Many marine animals that float near the surface are highly transparent, giving them almost perfect camouflage. However, transparency is difficult for bodies
