The sail jellyfish is a small type of jellyfish, only about 8 cm long. The most unique is that on one side of the jellyfish is a sailboat-like floating bladder. According to research, sailing jellyfish can also commit suicide like whales. Hundreds of millions of sailing jellyfish carcasses appear on beaches on the west coast of the United States. What is the truth about the mass suicide of sailing jellyfish?
What kind of jellyfish is sail jellyfish?
The sail jellyfish is a marine plankton of the genus Sail jellyfish in the family Hydra Silver Coin Jellyfish. Jellyfish floats have hard chitinoids, oval, disc-shaped, and 5–8 cm in diameter. It is named after the triangular windsurfing board above the float. Tentacles with long spiny cells. In everyday life, the body of the float is cyan-blue, and the sail is colorless and transparent. It floats on the surface of the water with the wind or current.
Sail jellyfish are close relatives of jellyfish, characterized by inflatable sail-like floating sacs with spiny antennae, genitals and vegetative people below. What does a sail jellyfish look like? Jellyfish is characterized by an inflatable sail-like floating sac with spiny-like tentacles above, propagules and vegetative bodies below. Jellyfish floating sacs are rigid chitinous, oval, disc-shaped, 5–8 cm in diameter. It takes its name from a triangular windsurfing board above the buoyancy bag. The float body consists of more than 10 concentric rings with an internal radial network of thin tubes, filled with gas. There is a major vegetative body in the center of the ventral surface of the cyst, surrounded by many small nutrients. There are propagules between small vegetatives. At the edge of the floating sac there are many finger-like bodies, which are hollow with the ends closed, acting as sensations and predators. In everyday life, the body of the float is cyan-blue, and the sail is colorless and transparent. It floats on the surface of the water with the wind or current. In strong winds, groups of people are often driven to the curved sea. A common species is the sail jellyfish.
Sail jellyfish mass suicide: On the west coast of the United States, a fisherman came to the beach and saw a large expanse of blue. As he approached, he saw thousands of sail jellyfish, transparent and purple-blue in color. It looks like a blue beach. According to rough statistics, the number of sail jellyfish is at least hundreds of millions, most of them are dead, the rest are almost dying. Not far away, a large number of sail jellyfish were also brought up. Why do sail jellyfish commit mass suicide?
Explanation 1: Some believe that the mass suicide of sail jellyfish is due to loss of direction. The way sail jellyfish have children is special. They float in the ocean for years, and each time they want to reproduce, adult "sail jellyfish" germinate and replicate very small jellyfish. These small jellyfish are a scaled-down version of the large jellyfish. After reproduction, they slowly sink more than 2,000 meters underwater to grow and develop, and produce sperm and eggs to reproduce. Sailing jellyfish gather from all sides and, due to unknown directions, accidentally hit the beach.
Explanation 2: Schools of fish chasing fish in the ocean are actually a fearsome hunter. Schools of fish pass by in groups, washing away everything they pass. Therefore, it is suspected that the mass suicide of sail jellyfish was due to schools of fish attacking them.
Explanation 3: Storms hitting the oceans are so destructive that even the smallest storms can set off huge waves. Once plankton encounter a storm surge, the chances of escape are slim: strong winds and roaring waves will send them to the beach to boil them to death, or they will be smashed directly into pieces. The Truth About the Mass Suicide of Sail Jellyfish: In fact, all three of the above statements are possible. But after expert research, it is believed that the cause of the collective suicide of sail jellyfish is actually the increase in sea temperature. As the sea temperature rises, sail jellyfish appear from the deep sea and are blown onto the beach with the wind and waves. Once stranded on the beach, their bodies quickly dry out and die.
