Now let us take a look at whether the giant deep-red jellyfish is poisonous!
Is the giant deep-red jellyfish poisonous?
The giant deep-red jellyfish is poisonous. The giant deep-red jellyfish is a kind of jellyfish, named for its body color, and it is the most fascinating-looking among many jellyfish. Although the red jellyfish looks very beautiful, its slender tentacles have deadly venom, so they must never be touched. The tentacles are covered with stinging cells that, like venomous threads, can shoot out venom; after prey is stung, it quickly becomes paralyzed and dies, so one must never be careless, to avoid accidents.
Which jellyfish are the most venomous?
1. Box jellyfish: each tentacle of the box jellyfish has enough toxin to kill 50 people, and it can stop a person's heart and lung function within 3 minutes. Since 1884, at least 5567 people have died from this animal, and the death rate it causes is even higher than that of snakes, sharks and saltwater crocodiles.
2. Portuguese man o' war: the deadly toxin secreted by the Portuguese man o' war comes from tiny stinging cells in its tentacles. Although the toxin secreted by a single stinging cell is negligible, the toxin accumulated by thousands upon thousands of stinging cells is no less intense than that of any venomous snake in the world today.
3. Sand jellyfish: the adult sand jellyfish has an umbrella diameter of 25 to 60 cm, with a maximum of nearly 1 m; the outer umbrella surface is smooth, and the mesoglea is thick and hard. Its stinging cells are highly toxic; after a human is stung, the skin becomes red and swollen, painful and itchy, and in severe cases there may be shock, or even death.
4. Lion's mane jellyfish: the lion's mane jellyfish is a creature that can cause human death, but it rarely moves in places where humans go. The stinging cells on its tentacles contain venomous needles and capsules filled with venom; when the venom enters the human body, it quickly causes paralysis and death.
What kinds of jellyfish are there?
1. Box jellyfish: the entire umbrella of the box jellyfish is cube-shaped, and they are distributed in tropical and subtropical shallow seas, with a few living a drifting life in the open ocean. The stinging cells on their tentacles are highly toxic. Common representative species include the hand-drawn jellyfish and the box jellyfish.
2. Crown jellyfish: the jellyfish body of the crown jellyfish is dome-shaped, conical, or flattened, but there is a constricted groove in the middle of the outer umbrella that divides the umbrella into upper and lower parts, and the corresponding gastric pouches are also divided into upper and lower parts. They are mainly deep-sea species, such as the rim-leaf jellyfish.
3. Cross jellyfish: the cross jellyfish is a scyphozoan that lives a sessile life; its body is formed by the union of the polyp form and the medusa form, and it is often distributed in colder seawater, attached to seaweed. Examples include the trumpet jellyfish and the tall-cup jellyfish.
4. Flag-mouth jellyfish: the umbrella of the flag-mouth jellyfish is bowl-shaped or butterfly-shaped, and the umbrella margin has 8 to many notches, with tentacle pouches in the notches. The vast majority live along the coast. Common species include the moon jellyfish, the swimming jellyfish, and the sea nettle jellyfish.
5. Root-mouth jellyfish: the root-mouth jellyfish is close to the flag-mouth jellyfish, but its mouth is not in the middle of the body; instead it is located on movable tentacles, and it has a small opening that can take in small food molecules in the water. Representative species include the edible jellyfish and the saltwater jellyfish.
