Close-up of fish melanophores. Fish coloration is produced through specialized cells called chromatophores. The dermal chromatophore is a basic color unit in amphibians, reptiles, and fish which has three cell layers: "the xanthophore (contains carotenoid and pteridine pigments), the iridophore (reflects color structurally), and the melanophore (contains melanin)".

the two stripe damsel is a very hardy fish. This fish is perfect for the beginner marine aquarist, as it can tolerate substandard water quality. This fish is highly aggressive, and requires many hiding places. 10 cm (3.9 in) Yellow damsel: Amblyglyphidodon aureus: Yes: 13 cm (5.1 in) Yellow threespot Dascyllus: Dascyllus auripinnis: Yes [49]: 205
Pelagic fish. Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that live on or near the bottom, and reef fish that are associated with coral reefs. [ 1 ] The marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 ...
Coloration of the northern red snapper is light red, with more intense pigment on the back. It has 10 dorsal spines, 14 soft dorsal rays, three anal spines and eight to 9 anal soft rays. Juvenile fish (shorter than 30–35 cm) can also have a dark spot on their sides, below the anterior soft dorsal rays, which fades with age. [2]
Fish scale. A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term scale derives from the Old French escale ...
Fish have cells called chromatophores that produce pigments that reflect light and give the fish coloration. The color of a goldfish is determined by their diet, water quality, and exposure to light, along with age and health. [49] Because goldfish eat live plants, their presence in a planted aquarium can be problematic.
Garibaldi (fish) The Garibaldi, known historically also as the Catalina goldfish and marine goldfish and now commonly as the Garibaldi damselfish (Hypsypops rubicundus) is a species of bright orange fish in the damselfish family. It occurs in the subtropical northeastern part of the Pacific Ocean. The English name, Garibaldi, is based on an ...
Bright coloration of orange elephant ear sponge, Agelas clathrodes signals its bitter taste to predators. 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.
