Green Bird's Nest Coral is a group of hard corals belonging to the Pocilloporidae family. It usually forms a shrub like cluster structure and is mainly distributed in East Africa, the Red Sea, and the West Indo Pacific region. This type of coral has thicker branches and blunt ends. The coral holes are mostly arranged in rows and have a cover like structure similar to Stylophora. They usually grow on shallow reef slopes, especially on the back reef slopes, with a depth of up to about 25 meters.

The coral holes are mostly arranged in rows and have a cover like structure similar to Stylophora. They usually grow on shallow reef slopes, especially on the back reef slopes, with a depth of up to about 25 meters.

This type of coral lives in tropical and subtropical regions of the Indian Ocean and Pacific Ocean. They usually form clustered groups up to 30 centimeters in height, with irregular wart like protrusions on the surface. Cauliflower coral comes in a variety of colors, including green, pink, yellow brown, or light brown. This type of coral is the main builder of reefs, growing rapidly and having strong competitiveness. Their tentacles extend at night to prey on plankton.

Coarse bare ribbed coral is a species of animal in the bare ribbed coral genus of the bare ribbed coral family. The coral shell is branched, with short and wide branches that can merge with each other, and the top is a bifurcated fan-shaped structure. The valleys between the ridges on the surface of the non coral cup are discontinuous and shallow. There are flat pillars or protrusions on the pillars at the bottom of the valley. The spacer is slightly protruding, with primary and secondary spacers arranged alternately. The edges of the spacer have teeth, and there are particles on both sides. 6-9 spacers are connected to the shaft column, and they are pink yellow or rouge red in daily life. Distributed domestically in Hainan Island, China.

Brain coral is circular in shape with deep grooves on its surface, resembling a human brain. This type of coral is composed of rows of coral polyps whose tentacles are neatly arranged on both sides of the coral polyps, with their mouths long at the bottom and shaped like grooves. The circular structure of corals helps them withstand the impact of waves. Lingshui Xincun Port, Xinying Linchang, Weizhou Island, Huaguang Reef, Panshi Island, Xian'e Reef, Xinyi Reef. Features: Coral skeletons are pleated and leaf shaped, with edge leaves or groups forming a semi tree like shape, and small leaves of varying sizes twisted into ear shaped protrusions in the center. On the surface of the non coral cup, the septum forms a continuous ridge, with a thick center and thin edges. Crack irregularly at the end of the blade.

The cup-shaped coral genus has a total of 18 species. It is a single or group animal of the Hydra type, with a body that is six fold symmetrical with two radiations. The oral wall invaginates to form an oral passage, and the endoderm of the gastric cavity wall extends centripetal to form a diaphragm. Muscles are well-developed, with cells present in the mesosphere. Reproductive cells originate from the endoderm and can form bones. Seafood, group, with bones, can be used to build reefs, and the presence of mouth channels makes its body exhibit two radiating symmetries. Having a diaphragm, the diaphragm can support increasing the digestive area. Diaphragm filaments have stinging cells, and both the inner and outer germ layers have stinging cells. Genital glands originate from the endoderm. The color is usually brown, pink, or yellow. Distributed from the Indian Ocean to the Pacific Ocean.
