Grass sea dragon is very camouflage. It is covered with leafy appendages, just like an algae floating in water, showing green, orange, gold and other body colors. It will only show its whereabouts when it swings its small fin or turns its two eyes that can move independently. Ye Hailong has no teeth or stomach. They feed on krill and live in the low temperature and low waves of 10~ 12C.
Leaves leafyseadragons, which look like seaweed leaves and dragons, are undoubtedly one of the most amazing creatures in marine fish. In addition to Ye Hailong, there is also a kind of weed-false herring, both of which are found only in the offshore of South Australia. At present, these two kinds of sea dragons have been listed as protected animals, especially in Ye Hailong, which has a delicate and gorgeous appearance and is quite rare and precious.
attitude
The grass sea dragon can grow to 45cm, and its body is composed of bone plates, and it has appendages extending like seaweed leaves, so that Ye Hailong can disguise itself as seaweed and safely hide in unpolluted offshore waters, where there are many algae and the water flow is extremely slow. Sea dragons have no teeth, and their mouths are like straws, which can suck plankton and sea lice into their stomachs like shrimps. The grass sea dragon is about the size of Ye Hailong. The difference is that grass sea dragons have red, purple and Huang San colors, and some have sapphire stripes on their chests. The appendages on the body and tail are much smaller than those in Ye Hailong, and their appearance is closer to the hippocampus. Grass sea dragon: creature, fish, sea dragon, also known as algae dragon, belongs to the same family as seahorse, and is very similar in appearance, living habits and eating habits. The difference is that the body of a sea dragon is bigger than that of a seahorse. Sea dragons have leaflike appendages on their heads and bodies, and their tails are not coiled like seahorses.

The grass dragon belongs to the family Syngnathidae, which belongs to the same family as hippocampus and tubular fish. The grass sea dragon mainly inhabits the shallow water area with good concealment of reefs and dense algae. The general depth of habitat waters is 4-30m, but Ye Hailong can also be found in waters with a depth of 50m. Larvae grass sea dragon generally lives in shallow water, while adult grass sea dragon likes to live in the sea with water depth of 10 meter.
Grass sea dragon is an excellent camouflage master in marine life, and its camouflage props are fine leaf-shaped appendages. The body of the grass sea dragon consists of a bone plate, and a petal-like appendage like a seaweed leaf extends to four gais. In addition, the grass sea dragon also uses its unique back-and-forth movement mode to disguise itself as seaweed to avoid the harm of the enemy. The body color of adult grass sea dragon can vary from green to yellow-brown because of individual differences and the depth of habitat sea area.
Like seahorses of the same family, grass sea dragons often have the phenomenon of "role inversion" in the process of hatching their offspring. August every year and March every other year are the breeding seasons of grass sea dragons. During the mating period, the females will expel a certain number of eggs (generally 65,438+0,50-250) from the females and put them in a pouch formed by folding two skins at the tail of the males, and the males will undertake the heavy responsibility of incubating eggs. Generally, it takes about 2 months for the eggs of the grass dragon to hatch into the larvae of the grass dragon.
In recent years, due to the serious pollution in the shallow waters of southern Australia, and the fact that the grass sea dragon is not easy to swim, it is often motionless and has high ornamental value, which makes this rare animal killed by some lawless elements. In addition, the probability of oviposition, fertilization, hatching and survival in Ye Hailong is very low, only 5%, so the Australian authorities have listed it as a rare animal under special protection.
type
Like seahorses, the most special thing about sea dragons is that males are responsible for pregnancy and childbirth. During the mating period, the female sea dragon arranges 150 to 250 eggs in the pouch at the tail of the male sea dragon, and the male sea dragon breeds these small sea dragon eggs for six to eight weeks until they become mini sea dragon babies, and then gives birth to them. August to March is the breeding season of sea dragons every year. During this period, a male sea dragon can usually hatch two nests of eggs. Unfortunately, in the natural environment, only about 5% of young sea dragon babies have a chance to survive and grow up.
human population
The name grass sea dragon comes from ancient fairy tales in China. After the female sea dragon lays eggs, these fertilized eggs will spend about 8 weeks in the honeycomb area (egg holding point) under the tail of the male sea dragon, and the male sea dragon can carry 150 to 200 eggs. In Australia, they are called Australian seahorses. Since 1982, the South Australian government has listed the grass sea dragon as a protected animal.
Although it is not as difficult to find as other mysterious marine animals, fewer and fewer people have seen this special sea dragon with their own eyes. Due to environmental pollution and industrial waste flowing into the ocean, grass sea dragon is on the verge of extinction. In recent years, the survival of the sea dragon has been greatly threatened. Not only is the pollution problem in the shallow waters of southern Australia getting more and more serious, but also the beautiful and lovely appearance of sea dragons, their bodies that are not easy to swim quickly and their habit of often staying still make them often caught by some immoral people. At present, these two kinds of sea dragons have been listed as protected animals, especially in Ye Hailong. They have a delicate and gorgeous appearance and are quite rare and precious.
