Is the jellyfish dead with its tentacles pointing up?

Not necessarily, it's best not to touch it with your hands. Animals can do this when they get dizzy.

Jellyfish that do not move is dead. Jellyfish slowly turn into water after they die, because 90% of the jellyfish's body is water.

You can find something clean and move it to see if it can still move. In order to avoid such a situation, when feeding, it is necessary to ensure that the temperature is 25, if the temperature is too high, it will reduce its activity, and it will sink and die. If the water quality deteriorates, the water should be changed in time, and care should be taken not to harm the jellyfish when changing the water.

Precautions for farming jellyfish:

1.Water Quality Requirements:

Jellyfish are marine creatures, so they should be raised in seawater. Generally, when breeding, it is necessary to change the water, and the water can be changed by 1 3 in two weeks, so as to avoid the pollutants in the water blocking the jellyfish's ability to receive, and it will also affect its swimming speed.

2.Preparation for breeding:

You can buy an aquarium for breeding jellyfish, put in a thermostat, and adjust the temperature to about 25 degrees.

3.Food Preparation:

Insects and shrimp can be fed to jellyfish, and plankton is their best food. If you see your mouth change color during feeding, it means that you have eaten enough. Based on this information, the number of feedings can be determined to avoid overfeeding and polluting the water quality.

4.Light Source Management:

Jellyfish generally need a light source, there are single cells in the body of jellyfish, and they need to carry out photosynthesis, so that oxygen can be transmitted to the jellyfish, and the waste produced by the jellyfish is also the food of the single cell, so they are dependent.

There can be many reasons why jellyfish die, here are some of the possible causes:

1.Unsuitable water temperature: The ambient temperature of jellyfish activity is required to be 22-25 degrees, if the water temperature is too low or too high, it will affect the vital signs of the jellyfish and lead to death.

3.Long-term non-replacement of water: The metabolites of jellyfish will affect water quality, and long-term non-change of water will make the water quality worse, resulting in the death of jellyfish. It is recommended to change the water once a week, 1 to 3 times at a time.

4.Inappropriate light intensity and duration: Strong light has an inhibitory effect on the growth of jellyfish, and jellyfish need the right amount of light to maintain life activities. If the light intensity and duration are not suitable, it can also cause jellyfish to die.

5.Insufficient inorganic salts and trace elements in water: Inorganic salts and trace elements in water are very important for the growth and development of jellyfish, and if these substances are lacking in water, it will also lead to jellyfish death.

6.Disease Infection: Jellyfish can be infected with various diseases such as bacterial diseases, viral diseases, fungal diseases, etc., which can cause the death of jellyfish.

7.Accidental Injury: During a water change or premature transport, a jellyfish may suffer accidental mechanical damage that can lead to death. Cover wheels.

In short, to maintain the health of jellyfish, it is necessary to provide the right water temperature, sufficient food**, clean water quality, appropriate light intensity and duration, and the right amount of inorganic salts and trace elements. At the same time, care should be taken to avoid accidental injuries and prevent disease infection.

Are you buying a freshwater jellyfish or a saltwater jellyfish?

1. It may be that the trace element content of inorganic salts in water is insufficient.

2. The most important reason is that the temperature is too low now, and the general optimal growth temperature of jellyfish is 25 degrees, so if necessary, install a device.

3. It is also necessary to supplement the jellyfish to determine that the liquid feed has a seawater rotifer feed designed for soft bodies, when it is found that the digester and mouth in the jellyfish wing turn orange, it means that the jellyfish has been full.

4. The water change cycle is generally less than two times a month to dig Kai, try not to hurt the jellyfish, do not suck the jellyfish when draining, avoid the generation of bubbles when feeding water, and do not give water too quickly. etc., the water cannot be changed frequently.

Jellyfish filial piety is not necessarily dead.

Jellyfish are marine creatures whose body structure allows them to swim and hunt in the water. Although jellyfish have a relatively short lifespan, they can increase their lifespan by reproducing and regenerating, among other things.

If the jellyfish are motionless, it is possible that they are resting or playing dead. While resting, jellyfish contract their tentacles and relax their bodies to keep their bodies balanced and stable. And playing dead is a self-protection mechanism, when jellyfish feel threatened, they will play dead to avoid being detected by the ** eater.

However, if the jellyfish is motionless and the tentacles have retracted, then this could be a sign of death. At this point, you can try gently touching the tentacles with your fingers to see if they are still responding. If there is no response, then the jellyfish may have died.

In addition, if the jellyfish is unable to maintain its balance in the water, or if the body is cracked or decayed, it can also be a sign of death.

In short, judging whether a jellyfish is dead or not requires a combination of factors, and it is best to make a conclusion based on confirming the tentacle reaction, balance state, and physical condition.

No. The jellyfish will not die directly when they leave the water, and they are motionless because the jellyfish cannot move after leaving the water, and they have no ability to move, so the jellyfish is not dead if they are motionless. Jellyfish (English name:

Jellyfish): is an important plankton in the aquatic environment, including spinophiles, Jellyfish, Crucifera, and Cubic Water Ruler. The trapped liquid jellyfish is a very beautiful aquatic animal.

Most of them are poisonous and should not be touched with your hands. Generally, if you are stung by a jellyfish, you will only feel burning pain and redness. However, in the sea from Malaysia to Australia, there are two kinds of jellyfish called sea bee jellyfish (box jellyfish) and hand jellyfish, which secrete very poisonous, and if stung, they will die within a few minutes, so they are also called killer jellyfish.

After pickling, sea mussels are a delicacy on many people's tables, but they should not be eaten too much. (The umbrella of the jellyfish is the sea stinger skin that we usually eat, and the tentacles of the jellyfish are the sea stinger head grinding branches, and the red one is usually bought when buying the sea stinger skin, which is relatively delicate and delicious.)

Jelly fish (English name: Jelly fish): It is an important plankton in the aquatic environment, belonging to the class of spinylands and bowls.

Jellyfish are a very beautiful aquatic animal. Its body is shaped like a transparent umbrella, and the diameter of the umbrella body can be large and small, and the diameter of the umbrella body of the large jellyfish can reach 2 meters. There are some whisker-like tentacles on the edge of the umbrella, and some tentacles can be up to 20-30 meters long.
