One day in summer vacation, our family went to Hainan to play. The blue sea is boundless, and the spray is like a naughty child, rushing to the beach at one time and retreating quickly at another.
I picked up shells on the beach. A green shell caught my attention. The surface of the shell attracts some small white things, which are like small volcanoes. Take a closer look at the crater, which is one-on-one with countless tentacles. I put it in the bottle, its long tentacles gently shaking with the water. Eh, what is this? Ah, this is the legendary barnacle! I remember it said in the book that barnacles are parasites attached to crustaceans, which feed on plankton. There are two "Gates" on them. When the tide goes out, the two "Gates" will be closed to keep the water. I just saw them on TV before. I didn't expect to see a living barnacle in front of me today. I was very surprised.
I picked up the bottle and looked left and right. I couldn't help it. I really want to take it home! But my mother told me that once barnacles leave the ocean, they can't survive. So I decided to release it to the sea.
The next day, I carefully held the bottle and ran to the sea, pouring the barnacle into the sea. A wave came and hugged the barnacle into the arms of the sea mother. Goodbye, barnacle, I hope I can see you next time!
