Observing jellyfish

Saturday, July 7, 2019

I bought six small jellyfish from Liugong Island. They are large, small, some have long tentacles, and some have short tentacles. But they all have one thing in common: no mouth, no hands and feet, no mind, no eyes, no nose, and hair on the tentacles. These six little jellyfish have some love to play, and some love to sleep, like a long-legged small mushroom wearing a stealth suit.

When they move together, it's like a hot air balloon swells up and stretches out. It also seems to be a fairy swimming in the river, beautiful. But the jellyfish has no mouth, no eyes, no mind, what to eat? Later, through the Internet, I knew that the jellyfish feed on plankton in the water. It turns out that their tentacles are their intestines. Once the plankton hits its tentacles, the tentacles will shoot out the poisonous juice. They will be poisoned first, then they will be directly decomposed and digested with the cousin. The jellyfish eats like this!

Jellyfish is really a magical creature, it is a growing knowledge!
