As sanctuaries for marine life, coral reefs are not only extremely important to marine ecosystems, but also provide us with abundant products and great economic value. Are corals plants or animals?

It is a real animal. Coral refers to the calcareous skeleton secreted by coral polyps, and what condenses under temperature conditions is mostly red, but also black or white.

Many coral individuals are colorful, and the bright colors are not inferior to various flowers on land. Some coral species also have amazing fluorescent effects.

Different types of coral can build a three-dimensional coral reef ecosystem in the aquarium.

Main characteristics of corals.

Corals are shaped like branches and have bright colors and can be used as decorations. Gem-quality corals are red, pink or orange-red.

The red color is due to the coral's absorption of about 1% of the iron oxide in seawater during growth, and the black color is due to organic matter. Has a vitreous to waxy sheen and is opaque to translucent.

Coral habitat.

Corals live in tropical and subtropical waters and are formed by aggregations of coral polyps.

Individual polyps are several millimeters long and have many tentacles that are used for photosynthesis and preying on small plankton.

How corals reproduce.

Corals can reproduce sexually or asexually. Corals reproduce in two ways: sprouting or oviparous.

Most corals use budding, where polyps form small buds that then develop into new polyps.

Occasionally, corals also reproduce by spawning, from which larvae hatch into adults.

Coral has certain medicinal value.

It has a sedative and sedative effect and can be used to treat symptoms such as restlessness, restlessness, insomnia and more dreams.

It also has the effect of hemostasis and eyesight, and helps to treat burns, nosebleeds, cataracts and other diseases.

Beautiful coral reefs also provide us with an abundance of products. At present, there are more than 600 species of coral reef fish, and more than 10,000 species of creatures inhabit them. It is not only a source of food, but also many new medicines are extracted from it.

Corals have important functions such as protecting the coast, maintaining biodiversity, maintaining fishery resources, and attracting tourism.
