At first, the huge sand anemone did not take the small and seemingly harmless nudibranch seriously. It waved its poisonous tentacles wantonly, intimidating the nudibranch that was approaching it.
Xiang Yang, who was watching the video at that time, felt that the nudibranch would definitely escape in a panic. After all, whether in terms of body size or attack and defense methods, the sand anemone is far superior to the nudibranch.
These two are not competitors of the same level at all.
Unexpectedly, just as Xiang Yang had that thought, the nudibranch marine creature jumped up, drew a parabola in the ocean with its body, then accurately passed through the heavy tentacles and rushed directly into the big mouth of the sand anemone.
The sand anemone waved its tentacles contentedly after devouring the nudibranch.
However, just one or two seconds later, the sand anemone quickly retracted its tentacles and began to struggle desperately.
It turned out that the nudibranch had drilled into the body of the sand anemone and was devouring its internal organs bit by bit.
The injured sand anemone twisted wildly, waving and flapping its poisonous tentacles, but it was completely unable to resist the attack from within its body.
However, the clownfish and anemone shrimp that parasitize on sand anemones are no match for the nudibranch marine creatures.
The sand anemone in the video struggled for a while and then became motionless, obviously dead.
Only after the sand anemone lost its life did the nudibranch emerge from its belly and begin to enjoy the food.
Nudibranchs love to eat the poisonous tentacles of sand anemones.
The sight of them eating was extremely bloody and horrifying.
They will eat the poisonous stingers on the tentacles of the sand anemones together with the food. After eating, the nudibranchs will twist their bodies so that the poisonous stingers will pierce their bodies with holes, making it look like a person being pierced by thousands of arrows.
However, even if nudibranchs are riddled with holes from the stingers of sea anemones, they will not die.
Although their bodies are riddled with holes and look scary, they are actually not dangerous at all.
In fact, in order to protect themselves, nudibranch marine creatures pass the poisonous spines in their bodies out through the cavities in their bodies without causing any harm to themselves.
Nudibranch marine creatures can use the internal air pressure of their bodies to firmly attach those thorns to their backs. When needed, it is their means of defending against natural enemies. When not needed, they change the pressure in their bodies by squeezing and deforming their bodies to remove all the thorns.
To sum up, this method of self-defense of "using poison to defend against the enemy" means that we don't have guns or cannons, but the enemy makes them for us. This is very rare among animals, and currently the only creatures known to have this skill are nudibranch marine organisms.
Moreover, this skill is also a special skill among nudibranchs. Not all nudibranch marine creatures have this skill.
Only those nudibranch marine organisms that like to prey on Hydrozoa can do this. They can store most of the nematocysts in the horns on their backs without causing any harm to themselves.
After experiments, scientists discovered that the secret of nudibranch marine life's ability to avoid injury is that it has a special type of cell with very large vacuoles in its body.
In addition, it is worth mentioning that nudibranch marine organisms all reproduce asexually.
They are hermaphrodites, and each nudibranch acts as both father and mother during the breeding season.
Spring is the breeding season for nudibranch marine organisms. Divers often find several or even dozens of nudibranch marine organisms linked together in spring.
This is an adult nudibranch nurturing and protecting a young nudibranch.
There are not many hermaphroditic animals. Nudibranch marine organisms have two very complete reproductive systems. They can lay many eggs at a time. Those eggs will stick together into long egg cords and attach them to nearby rocks or corals, just like blooming roses, red, white, yellow, all the colors of life.
Someone once fished out an 18-meter-long egg rope from the bottom of the sea. After statistics, it was found that it was made up of 108,000 eggs.
Of course.
Under normal circumstances, less than one-tenth of the 108,000 eggs can hatch.
Because nudibranchs have so many natural enemies, normally only one out of thousands of eggs can grow into an adult, and the chance of survival is shockingly low.
The reason why nudibranch marine organisms have not yet become extinct is probably related to their growth cycle: they grow very fast.
It only takes two to three months for a nudibranch to hatch from an egg and grow into an adult.
Since there are fish feeds specially made for raising nudibranch marine life on the market, it would be much easier to raise these nudibranch marine life. Xiang Yang first thanked Li Chao, and then sent two crew members on duty to carry the sea tank to the top floor of the cabin. He planned to put the sea tank in the library as a decoration.
"Brother Xiang, I'm leaving first." Li Chao said goodbye to Xiang Yang: "If you are free during this period, please come to my hotel and taste the cooking skills of my chef. The ingredients used are bluefin tuna."
Xiang Yang would not be so foolish as to agree. If Xiang Yang had to pay for something that cost tens of thousands of yuan per pound, he would not be willing to do so. If he asked Li Chao to treat him, he would be a bad person. He said politely, "I will come if I am free."
He thought to himself, I'm going out to sea these two days, so I definitely won't be free.
Li Chao waved his hand and said, "Let's go."
"Bon Voyage."
After Li Chao left, Xiang Yang stood on the deck for a while, thinking about some things in the future.
Originally, Xiang Yang wanted to treat the crew to some midnight snack.
As a result, until after nine o'clock in the evening, the crew members who went to Huhai Town to play had not returned. Xiang Yang guessed that they must have had too much fun, so he didn't wait for the crew members to come back. He ate some snacks to satisfy his craving, took a shower on the boat, and then headed home.
The house is not renovated and the living environment is not as good as the room on Xiang Yang's boat. However, because his parents are there, Xiang Yang usually lives at home whenever he comes back.
Xiang Yang is now relatively well off, so he thought of renovating the house.
Whether it is a fine decoration or a simple decoration, Xiang Yang still needs to discuss some specific matters with Xiang's father.
When I got home, Xiang's mother was video chatting with Xiang's father.
Xiang's father went to Longcheng City and has not returned yet.
Ever since Xiang's father started collecting seafood, he went to Longcheng more and more often, often staying there for a day or two.
