The ocean is a fairytale world: light and beautiful jellyfish like graceful dancers, dancing softly with the currents; starfish are like beautiful colored stars, sleeping leisurely on the bottom of the sea. But don't be fooled by their beautiful appearance. In fact, some of them are good at using poison, and some have a powerful destructive ability... Let's roam the oceans together and learn about these beautiful but unpleasant marine life.
The Big Mac of Jellyfish - Lion Mane Jellyfish
Although the lion's mane jellyfish is beautiful in appearance, it is very fierce in temperament and belongs to the carnivorous animals. They are colorful and glow in the water. When they swim in the sea, they turn into dazzling colored balls, which can attract many prey to automatically dedicate themselves. When the prey approaches, the stinging cells of the lion's mane jellyfish quickly shoot out venom, and the stinged prey tends to paralyze and die. Then, the lion's mane jellyfish uses tentacles to hold these prey tightly and suck it with the polyp under the umbrella body, each polyp can secrete enzymes, quickly decompose the protein in the prey, digest and absorb it in the coelenter.
However, it is not invincible in the sea, and there will be natural enemies to "conquer" it. The natural enemy of lion-maned jellyfish is the tortoise. Cockroaches can move freely through groups of jellyfish, such as lion-maned jellyfish, because their thick shells make it impossible for the spine cells on the lion's mane jellyfish tentacles to help them. Turtles can easily tear off the tentacles of lion mane jellyfish with their mouths, so that they eventually lose their resistance and become their own meal.
Sea poisoned wasps – box jellyfish
In the waters of Australia, northern New Guinea, the Philippines and Vietnam, there lives a super-toxic jellyfish that resembles a square box, hence the name "box jellyfish". Their "poison" scares people because they have stinging cells that store venom in their bodies, and they have created many horrific deaths.
The King of Poisons. The box jellyfish ranks third in the list of the world's top ten deadly animals, which shows how terrible the toxicity is! According to research studies, 1 tank of jellyfish was enough to kill 60 able-bodied adults. If unfortunately stabbed by a box jellyfish, the victim will feel a burning pain, and then the heart will stop beating in just a few minutes. However, box jellyfish are afraid of sunfish, turtles, acetic acid and things that are red in color!
Poisonous rays of light – arctic jellyfish
Arctic Xiaxia jellyfish with its own "colored lights". There are 8 meridian tubes on the Arctic Jellyfish, and there is a protein in the meridian tube that emits a strong blue light when mixed with calcium ions. Therefore, the Arctic Xia jellyfish we see is like a colored lamp, which is very beautiful. Around the ferocious Arctic Jellyfish, small herding fish often appear. This is because the small maki fish can attract some big fish to the jellyfish hunting range, bring food to the jellyfish, and after the jellyfish have a full meal, the small maki fish can also eat some surplus food, what a harmonious golden partner!
Dragnet. Although the Arctic Jellyfish is gentle and pleasant in appearance, it is very aggressive. Arctic Jellyfish generally have more than 1200 tentacles, each of which is tens of meters long, and these tentacles are all open like a net. Once prey falls into their large nets, life is often greatly threatened.
So some people have said: beautiful things are poisonous. What do you think of this statement? What other creatures do you know that are beautiful but dare not come close?
