The deal is done.
Xiang Yang invited Li Chao and Murong Zhenfei, "Brother Chao, Boss Murong, why don't you stay and have a quick meal before you leave?"
Li Chao smiled and shook his head. "Forget about eating. I seldom eat at night now. I have high blood sugar."
"But I have something to give you." Li Chao said with a smile.
"Oh? Give me something?" Xiang Yang looked at Li Chao curiously. He had everything he needed now and couldn't understand why Li Chao suddenly gave him something.
"First, to congratulate you on changing to a bigger ship. Second, to thank you for leaving the bluefin tuna for me. Third, didn't you give me a conch today? Reciprocity is the essence of friendship. If you don't accept it, then you are being pretentious." Li Chao said with a smile.
Hearing this, Xiang Yang laughed and said, "Could it be another bar? You gave me a bottle of Moutai Dragon Wine when I bought my first ship."
"Don't worry, not this time."
Li Chao shouted towards the truck, "Put the stuff up."
Xiang Yang raised his eyebrows. He noticed Li Chao's choice of words and looked towards the dock with curiosity. He wanted to see what kind of thing it was that required the word "lift".
On the truck side, two of Li Chao's employees were struggling to lift a fish tank from the truck.
Xiang Yang groaned, not knowing whether to laugh or cry, "Brother Chao, the gift you gave me is a fish?"
"Take a look first." Li Chao said mysteriously.
Xiang Yang waited for the fish tank to be lifted up, then lowered his head and took a look inside.
At first glance, Xiang Yang was fascinated by the things in the fish tank.
This is a marine tank.
A mixed-style marine tank.
The creatures in the fish tank have beautiful body colors, strange shapes, and rich colors that cannot be described in words.
Xiang Yang thought he had seen a lot, but he was still dumbfounded when he saw this sea tank. He now had only one thought in his mind.
Damn, fish can actually look so beautiful.
Oh my god, there are such beautiful creatures on earth!
"Do you know what this is?" Li Chao asked with a smile.
Xiang Yang raised his head and asked, "Is this a nudibranch?"
Although Xiang Yang was asking, his tone was very affirmative.
Nudibranchs are a general term for all mollusks in the order Nudibranch. Although most of them are only about ten centimeters long, they have the richest and most gorgeous body colors in the world and are praised by countless people who pursue beauty as "biological gems" or "undersea gems."
Xiang Yang stared at a nudibranch that looked like a giant snail for a long time.
It is royal blue all over with purple lace on its body, and carries a pink, transparent snail-like object on its back. Its two horns appear to have a cyan base color at first glance, but a closer look reveals a very dark black color with dots on them that look like fluorescent powder.
"You actually know about nudibranchs?" Li Chao asked in surprise.
Xiang Yang smiled and said, "Nudibranchs are widely distributed in all oceans, especially in warm shallow waters. Of course I know this kind of creature."
"Okay." Li Chao said depressedly: "I thought I could give you a surprise. I was surprised for a long time when I first saw nudibranchs."
"You can keep these nudibranchs on your boat as decorations." Li Chao pointed at the aquarium and said, "Don't think that nudibranchs are pampered just because they are beautiful. In fact, these colorful elves are extremely tenacious and are not very picky about the environment. They can grow in saltwater environments."
Xiang Yang nodded, he knew this.
Although this was the first time Xiang Yang saw a living nudibranch, he had read in books that nudibranchs can grow very large and beautiful as long as they are in clear water and warm sunlight. They are the real sea elves in the hearts of countless people.
Because of this, other creatures are often passed off as nudibranchs in the market.
Nudibranchs are actually pretty easy to identify.
The eyes of nudibranchs are generally only a quarter of a millimeter in diameter and have a very simple structure. From the outside, they really are just a small dot.
The internal structure of its eyes is also very simple, usually consisting of only a lens and five photoreceptors. They can only simply distinguish between day and night and are unable to see specific objects.
They sense the surroundings through two sets of antennae, the head antennae and the club antennae.
The tentacles on the head are very sensitive to touch and taste.
The rod-shaped antennae are used to detect odors.
Nudibranchs must have gill feathers on their backs that protrude from their bodies. They are their respiratory organs, and their function is the same as the feathers on Christmas tree worms. They are the main way to distinguish whether a creature is a nudibranch.
Although some sea creatures are not nudibranchs, they are often taken to the market by unscrupulous vendors to impersonate nudibranchs because of their bright colors.
Therefore, when identifying whether a marine creature is a nudibranch, you cannot rely solely on color. The gill feathers protruding from the back are the most reliable sign of nudibranchs.
Of course, there is no need to identify the nudibranchs in the aquarium that Li Chao gave to Xiang Yang. These are all genuine nudibranch marine creatures.
Xiang Yang stared at the sea tank for a long time.
Li Chao asked with a smile: "How is it? Do you like it?"
Xiang Yang nodded, "I like it, but Brother Chao, you should take it back."
"What's wrong?" Li Chao asked.
Xiang Yang smiled bitterly and said, "Most nudibranchs are carnivorous. There are too many species in the tank you gave me. Different nudibranchs have different feeding habits. Look at this pink one. It should eat sponges. Look at this sky blue one. If I am not mistaken, it should only eat hydrozoans. Some nudibranchs only eat exoanal animals or urochordates. This is a fishing boat. If I keep a group of these things on the boat, I won't have to work in the future."
"It's not that troublesome." Li Chao said with a smile: "There are special fish food, and barnacles and anemones are also their favorite snacks."
Speaking of sea anemones, Xiang Yang recalled a video he saw in college showing nudibranchs preying on giant sand anemones.
The sand anemone is a powerful protector of clownfish and anemone shrimps. It has a circle of poisonous tentacles that can spray out venom. Ordinary marine creatures dare not provoke such a terrifying creature as the sand anemone.
If a marine creature is unfortunately attacked by a sand anemone, it will be anesthetized at best, or die at worst. Few marine creatures will actively challenge sand anemones, but nudibranchs that feed on anemones are obviously an exception.
Xiang Yang remembered that the video showed a nudibranch staring at a sea anemone for a long time, and then quietly lurking towards the sand anemone.
It took the nudibranch nearly an hour to reach the roots of the sand anemones.
