When I came to the underwater world, my eyes were too busy.

First we came to the tropical rainforest area in the museum. Most of the fish here have bright patterns and various shapes. The map fish is flat and large, with red patterns on its body like a map; the parrot fish is brightly colored and is named because its mouth resembles a parrot's; the bag on the head of the Luohan fish is like a hat worn by a birthday boy; the long fish of the angel fish is The fins float in the water, like a fairy flying in the clouds and mist; the garden eel is even more peculiar, it likes to bury itself in piles of stones. Here you can see colorful marine life.

The emperor penguins, arctic foxes and beluga whales in the Polar Pavilion are posing. In the ocean tunnel, rays with serrated tails and ferocious-looking lemon sharks each occupy a corner of the tunnel, as if they are the kings here. The rays with huge pectoral fins swam lightly through the glass tunnel from time to time, leisurely...

After playing here for an hour, the sea lion brothers "Red Island" and "Dengdao" appeared, and they were there for us. There were performances such as playing volleyball and playing music. In addition, the three dolphins showed us their jumping ability and their tacit understanding with their trainers. Whether they were sea lions or dolphins, their performances were so amazing!

Extremely exciting!

“What is the underwater world like?” I often think about this question. Last night, I had a very strange dream...

In the dream, Dongdong and I drove a submarine and came to the underwater world. The bright light from the submarine suddenly turned the sea floor into daylight. What I saw in front of me was a moving picture: a group of small and exquisite fishes shuttled freely among the coral reefs in groups, as if they were playing hide and seek. At this time, a small dolphin quickly circled in front of our submarine, and it seemed to express a warm welcome to our arrival. Suddenly, the little dolphin abandoned us and ran away. I suddenly looked back and saw that it was a ferocious tiger shark approaching us step by step. I immediately pressed the electric gun in my hand to fire, and the tiger shark was so shocked that it ran away with its head covered.

We drove to the deepest part of the sea, and the water plants around us were floating with the waves, as if they were dancing women in a play. It was so beautiful! Suddenly, the water plants stretched out a pair of magic hands and entangled our submarine tightly, and we could not break free.

At this moment, the ringing of the alarm clock woke me up. oh! It turned out that I just had a sweet dream. I hope that in the near future, my dream will become a reality!

Xiamen is a very beautiful and prosperous city. Gulangyu is an island in Xiamen with beautiful beaches and tall Coconut trees and the spectacular underwater world!

We came to the underwater world. There were so many fish in it, it was so dazzling that we really didn’t know where to go. I was stunned when I saw a huge fish in front of me. This fish was almost two meters long, with a small head and a big tail. When I looked at the introduction board, I realized that it had a scary title, called Giant Dragon.

Turning back, a very long fish was staring at me. I guessed this fish was called an electric eel, and it turned out to be an electric eel. It will emit a lot of electricity. After it stuns the prey, it will rest for a while, and then eat its own spoils slowly. Some electric eels can even electrocute people to death. The current is so strong!

Next, I watched the dolphins heading the ball again, it was so amazing! It can also roll 360 degrees. After watching the performance, we were so happy that we couldn't describe the joy we felt at that time.

Xiamen is so nice. I will definitely come back next time. Goodbye, Xiamen.

Yesterday, my parents and I went to Changsha to visit the famous underwater world again.

The train is speeding, and my heart has already flown to the ocean of animals. When we arrived in Changsha, I couldn't wait to get out of the car with my parents and headed straight for our destination - the underwater world. Looking around, there are seas of people and flowers, so lively!

Entering the underwater world, I saw many friends: cute dolphins, big and stupid turtles, ferocious sharks, and majestic sea lions

Ten o'clock Around 10 minutes, we watched two wonderful shows: the mermaid show and the sea lion show. I think the most interesting one is the sea lion show. I saw two sea lions coming out, rolling with a ball on their heads, but the ball did not fall. The fun thing is that one can dance and the other can catch the ball.

The sky is getting dark, and I really don’t want to leave here, thinking: It would be great if I could live here.

Today, my mother and I happily went to Nantong Underwater World together.

I saw a red and yellow starfish lying peacefully under the glass. There was also a big red shrimp lying next to it, and a sea crab lying motionless with its large pincers raised.

Enter the museum. Wow, there are so many fish in it! There are tiny shooter fish, sinister crocodiles, and colorful lionfish.

After a while, we entered the mysterious undersea tunnel again.

A black shark bigger than my mother swam over. He seemed to be very greedy, and when he saw that we were not here to deliver food, he left in disappointment.

The underwater world not only makes me have fun, but also makes me gain knowledge. I got to know a lot of fish again.

I will go to the underwater world next time.
