Corals are the oldest marine life on Earth, emerging nearly half a billion years ago. Many people think that corals are plants, but in fact, from a biological point of view, corals are animals, formed by the aggregation of countless tiny corals.
Sunflower coral, also known as: short-tube star coral. In the water, the whole group gathers into a semi-spherical cushion, and the exoskeletons that resemble the crown of the calyx are exposed one by one.
The sunflower coral prefers to move in the shadows, and only stretches its golden tentacles in the shadows.
Kaleidoscope corals have 24 tentacles on each long tube-shaped polyp that stretches and sways, as if the flower opening cabin is charming.
Habits: Prefers to rest on dry coral reef floor beds, and mostly in heavily polluted natural seas.
Hammer coral is a type of coral found in Taiwan, the Philippines, the Ryukyu Islands and Australia. It is yellow or yellowish brown and consists of corrugated plate leaves. The population is generally hemispherical, with many and dense tentacles, and the apex is expanded crescent-shaped.
Hammer coral is a fairly common species, there are white, brown, green in color, and the tentacle end will also show different colors or fluorescent color, hammer common about two species in addition to a cornerstone long like a mountain, there is a branch-like growth.
Sponge is the most primitive multicellular animal, which has lived in the ocean for 600 million years, and has developed to more than 10,000 species, accounting for 1/15 of the marine animal species, which is a huge "family".
The anemone is a carnivore that grows in water and belongs to the genus Spiny. Although the anemone looks a lot like a flower, it is actually a predator, and its dozens of tentacles have a special spiny cell that releases toxins.
Gorgonian corals are dendritic groups with calcareous or central axes on the inside and bone fragments scattered on the outside, and there are about 1200 species of gorgonians.
Gorgonians feed on their pinnate tentacles, which grow in the direction of the currents in the sea so that they can catch the small marine animals and plants that the sea brings with it.
Bubble corals are nocturnal creatures, beautiful corals native to Fiji's coral reef regions, but their hydra body shrinks to see their white-brimmed bones.
When the bubble coral expands, the plump hydra will cover the entire skeleton. Like most LPS corals, their hydra body harms other corals that can be touched.
Button coral, also known as: sand group anemone, flower group sea anemone. The button coral group is a class of hexacarp that are relatives of corals and sea anemones and attach to rocks or reefs in shallow seas.
The color of button corals is arguably the most ever-changing – red, orange, yellow, green, cyan, blue, purple, almost anything. They live tightly together like flowers, forming a colorful "sea of flowers" on the coral reef.
To admire the corals, you can go to the aquarium, which generally has a dedicated coral water feature area. In Beijing, there are three main aquariums: Beijing Aquarium, Pacific Underwater World, and Fuguo Underwater World.
