1. When jellyfish move together, they will swell up like hot air balloons and swim aimlessly. There seems to be a fairy swimming in the river, which is very beautiful.
2. Jellyfish is transparent, and its body reflects the yellow of the cup cover, which is very beautiful. It has a semicircular, small and exquisite "head". Although small, all the organs of jellyfish are in it: mesothelium, digestive circulation cavity, gastric cortex, mouth and anus are all in its "head". Jellyfish seem to have all five internal organs.
3. In the aquarium, the moon-shaped jellyfish with filar silk is dancing with the waves, which makes people love like a fairy in the palace.
I bought six little jellyfish from Liu Gongdao. Some of them are big, some are small, some have long antennae, and some have short antennae. But they all have one thing in common: no mouth, no hands and feet, no brain, no eyes, no nose and furry tentacles. These six little jellyfish love to play and sleep, just like long-legged mushrooms in stealth suits.
Because it is too small, its tentacles are very short. It's short, but it has thorns on it. Every tentacle is like a poisonous sword. It is like a warrior with a sword, always ready to stab its enemies, but jellyfish don't fight with a sword but prey.
6. There are many small black spots in the cup where jellyfish are kept. Krill, a tiny creature that jellyfish love to eat, is as big as sesame seeds. Jellyfish only eat a little at a time, and there are enough creatures in the water to eat for a lifetime. When it eats, it always "sticks" the food with its tentacles before inhaling it through its mouth. At this time, it always swings its tentacles, as if celebrating the delicious food!
7. In the underwater world of Zuohai, I saw handfuls of swimming umbrellas-jellyfish. The jellyfish I saw were red, blue, white and black, most of them were white, some were very big, estimated to be 4 cm long, and some were very small, estimated to be only 2 cm.
8. I read in books that jellyfish can sting people, but why does such a lovely and interesting animal sting people? By the way, I forgot to mention that it is cute, because it looks like a fluffy ball; It's interesting, because one of them suddenly stopped moving and may be resting. It is like a vase, and the flowers in the vase are competing for the foreign minister.
9. Maybe jellyfish is really the real overlord of nature.
10. A giant jellyfish glides past you.
1 1. Jellyfish drag their tentacles for more than 30 meters in the sea to catch any prey that may be on the way.
This is the Antarctic jellyfish. This elegant creature floats in Antarctic waters near sea level. Its maximum body diameter can reach 1 m or more.
13. Jellyfish has neither blood nor brain, and its navigation in the sea mainly depends on nerve cells filled with colloidal substances.
14. The tentacles of jellyfish are covered with special cells, which can shoot "small arrows" at the victims, enough to paralyze them with venom and make people unable to move.
15. Although the structure of jellyfish is very simple, it has existed on the earth for more than 600 million years and nothing has changed.
