Happy Fishing Farm

Pick it up and look, as expected, this conch has actually died long ago, and the conch meat has been eaten. Now the one who occupies its shell is a man who looks a bit like the last one in the finale of Ultraman Tiga. Bizarre sea creatures of monsters.

"Hermit crab." Li Xuan handed the shell to Tang Yuting.

Tang Yuting didn't dare to pick it up with her hands, she opened the opening of the net bag and said, "Put it in."

Li Xuan nodded, put the shell on the mouth of the net bag, then stretched out two fingers, and knocked hard, the hermit crab fell out of the conch.

Seeing this, Tang Yuting said sympathetically, "The house is gone."

Hearing this, Li Xuan laughed dumbfoundedly and said, "Girl, why is your brain circuit different from that of ordinary people? Everyone says that a hermit crab is a kind of crab that likes to plunder. You say that this snail shell is its house."

As he said that, Li Xuan threw the snail shell into the ocean forcefully, "Generally, the snail shells that can be regarded as parasites by hermit crabs are well-preserved. When the hermit crab shrinks into the snail shell, it is alive A snail shell, there will be sea anemones on the snail shell as a means of defense, or it will be decorated with hydra as a camouflage, this thing is dangerous, if you see it in the future, it is best not to grab it with your hands."

When Tang Yuting heard it, she was shocked immediately, "Isn't sea anemone poisonous? Brother Xuanzi, then you were poisoned, right?"

Li Xuan couldn't help laughing, and said politely: "I'm an expert in this field, if I can still be injured by hermit crabs, then I won't have to go fishing again in the future."

Tang Yuting nodded slightly, and then said: "Brother Xuanzi, let's look around, maybe there are hermit crabs."

Li Xuan nodded. Hermit crabs are a kind of crabs that are distributed around the world. There are quite a few of them on the beaches of various places, especially in the intertidal areas, where they are very dense.

Of course, hermit crabs vary from place to place.

Hermit crab actually refers to more than just one kind of crab. It is divided into many kinds, which is a collective name for various organisms of the hermit crab superfamily.

All hermit crabs have a common specialty, that is, they like to live in the shell species of dead molluscs to protect their soft abdomen, so they are named hermit crabs.

Li Xuan was looking for it on the beach ahead, and Tang Yuting followed behind Li Xuan. She twisted the net bag with one hand, and carried the net bag far away from her body, as if she was afraid of the hermit crab.

When Li Xuan saw it, he couldn't help asking: "Tang Yuting, are you so afraid of this hermit crab?"

Tang Yuting blinked her eyes and said, "This crab looks like a spider and a centipede. It's really scary."

Li Xuan couldn't help laughing. The shape of the hermit crab is between a shrimp and a crab. It's long. It's okay to say that it looks like a spider and a centipede.

"Do you dare to eat it after it's cooked?" Li Xuan asked.

In fact, Li Xuan doesn't like to eat this stuff very much. If Tang Yuting doesn't even dare to eat it after it's cooked for a while, what's the point?

Tang Yuting nodded, "I'm not afraid if it's cooked."

Li Xuan nodded and continued to search.

Soon, the two found several hermit crabs.

Tang Yuting looked at Li Xuan, every time she tapped with her finger, the hermit crab fell out of the shell, and the size of the hermit crab happened to be about the same size as the shell, so she couldn't help but said: "There is a lot of water on the beach. There are so many sea snails, and every hermit crab can find a shell of the right size by chance."

Li Xuan rolled his eyes and said: "There is no such a coincidence in the world. The snail shell on the hermit crab is not found, but snatched. When the hermit crab finds a conch of the right size, it will be there. Attack it mercilessly until you kill it, tear it apart and get out of the shell, and then get in by yourself."

After the hermit crab gets into the empty snail shell, it will hook the top of the conch shell with its tail to prevent itself from being dragged out.

Li Xuan took out a hermit crab from his net bag and said, "Look, its legs are of different lengths. In fact, the division of labor between the long legs and the short legs is different. The short legs are responsible for supporting the inner wall of the shell, and the long legs It is responsible for crawling out of the shell, and once there is any danger outside, it will quickly retract its body into the shell, and then use this large pincer to plug the shell to prevent predators from pouring in from the entrance."

Tang Yuting raised her neck and looked carefully.

Li Xuan continued: "Besides, hermit crabs are not consistent with the crab shells they live in. They will change their shells several times in their life. The timing of changing shells depends on their size. Generally, they will choose Conch shells or shells are used as their shelters, but sometimes they also choose pillars, coconut shells, or corals as their shelters.”

At this time, Tang Yuting found another hermit crab, and she ran over excitedly, reaching out to catch it.

"Be careful." Li Xuan's eyes were straight and his hands were quick, he quickly grabbed Tang Yuting's wrist and said, "This one can't be grasped."

Tang Yuting looked at Li Xuan curiously, wondering why.

Li Xuan stared at the shell of the hermit crab and said, "On the shell that this hermit crab is carrying, there are sea anemones living in symbiosis with it."

Tang Yuting looked carefully, and sure enough, there was a small purple sea anemone blooming on the shell of the hermit crab.

Li Xuan said: "Sea anemones and hermit crabs are in a mutually beneficial and symbiotic relationship. The poisonous tentacles in the sea anemone will provide a certain degree of protection for the hermit crab, and the hermit crab will provide the sea anemone with habitats. site, and provide leftover scraps as food."

The symbiotic relationship between hermit crabs and sea anemones is entirely intentional.

The hermit crab will actively place the anemone in the appropriate position on the shell, so as to balance the center of gravity or effectively defend against the enemy.

Hermit crabs slowly lose the anemone-acquiring behavior when no predators are available.

This behavior resumes as soon as a predator is present.

What's more interesting is that there will be sea anemone battles between hermit crabs. Hermit crabs with strong force will snatch the anemone from hermit crabs with weak force.

Tang Yuting stroked her hair, and said suddenly: "Brother Xuanzi, last time my dad bought sea anemone and stewed chicken soup. It tastes super good."

Li Xuan shook his head with a smile, and said, "Let's go, let's go to other places, a few hermit crabs are enough, you can't eat too much of this thing."

Tang Yuting wondered, "Why can't you eat more?"

Li Xuan said: "This is because hermit crabs have very mixed feeding habits. They eat carrion and residues. A large amount of food residues will accumulate in their bodies. It's okay to eat a small amount of this thing, but it's really not good to eat too much. "

Tang Yuting nodded obediently. She knew that Li Xuan majored in marine biology. Since Li Xuan said so, there must be a scientific basis.
