Coral is an important part of the biological composition of the underwater world, and there are thousands of types of corals, and there are tens of thousands of species of each type of coral, but they can be roughly divided into five species according to color. They are: white coral, blue coral, red coral, golden coral, black coral, etc.

The color of corals is associated with symbiotic algae. When the number of symbiotic algae in the coral decreases, it will cause coral bleaching. So the color of the coral itself is white, with a small amount of blue and black, and the gem-grade corals are pink and red.

Red, pink, orange-red, black.

The color of a coral is related to its symbiotic algae, such as: zooxanthellae. When the number of symbiotic algae in the coral decreases, it can cause coral bleaching.

As a result, the coral bones themselves are often white in color, with a small amount of blue and black. Gem-quality corals are red, pink, orange-red. Red corals are due to the absorption of about 1% of the iron oxide in seawater during their growth, while black corals are due to their organic matter.

The surface of corals has colorful fluorescent pigments that regulate light, which play an important role in the effect of coral's symbiotic seaweed and the coral's adaptation to different light and dark environments.

Extended Materials. The main chemical component of coral stone is caco, which exists in the form of microcrystalline calcite aggregates, and a certain amount of organic matter is also included in the composition. Refractive index. hardness, density, black coral density is lower, for. Brittle. Strong blistering in case of hydrochloric acid. Non-fluorescent.

Coral is a sessile animal that cannot be moved, and because it looks like a flower-like tree, it is easy to mistake it for a plant that grows on the bottom of the sea. However, in reality, corals rely on symbiotic algae for photosynthetic conversion energy, rather than their own photosynthetic pigments.

Corals can be roughly divided into four colors: white, blue, black, and red.

The coral color is usually white, and a small number of corals are blue and black in color. Red, pink, and orange-red are gem-quality corals.

Red corals are formed when corals absorb about 1 of the iron oxide in seawater as they grow.

And when corals contain organic matter, black corals are formed. Black corals are less dense and have a vitreous or waxy luster.

Red, yellow and blue add up to brown coral

Get energy. The zooxanthellae are generally brown, yellow-green, and brown, which is determined by the pigment in the zooxanthellae. And polyps themselves also contain pigments. There are two types of pigments contained in polyps, fluorescent and non-fluorescent.
