Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination with pigments. For example, peacock tail feathers are pigmented brown, but their microscopic structure ...
Animal colouration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are brightly coloured, while others are hard to see. In some species, such as the peafowl, the male has strong patterns, conspicuous colours and is iridescent, while the female is far less visible.
Marine animals are incapable of making their own carotenoids and thus rely on plants for these pigments. Carotenoproteins are especially common among marine animals. These complexes are responsible for the various colors (red, purple, blue, green, etc.) to these marine invertebrates for mating rituals and camouflage.
Balaenoptera sibbaldii Sars , 1875. The blue whale ( Balaenoptera musculus) is a marine mammal and a baleen whale. Reaching a maximum confirmed length of 29.9 meters (98 ft) and weighing up to 199 tonnes (196 long tons; 219 short tons), it is the largest animal known ever to have existed. [3] [a] The blue whale's long and slender body can be of ...
The blue iguana's toes are articulated to be efficient in digging and climbing trees. The mature male's skin color ranges from dark grey to turquoise blue, whereas the female is more olive green to pale blue. Young animals tend to be uniformly dark brown or green with faint darker banding.
The blue-footed booby is on average 81 cm (32 in) long and weighs 1.5 kg (3 + 1 ⁄ 4 lb), with the female being slightly larger than the male. Its wings are long, pointed, and brown in color.

In the 1983 James Bond film Octopussy, the blue-ringed octopus is the prominent symbol of the secret order of female bandits and smugglers, appearing in an aquarium tank, on silk robes, and as a tattoo on women in the order. [28] [2] The Adventure Zone featured a blue-ringed octopus in its "Petals to the Metal" series.
Chromatophore. Chromatophores are cells that produce color, of which many types are pigment -containing cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods. Mammals and birds, in contrast, have a class of cells called melanocytes for coloration .
