In the ocean, jellyfish are fascinating creatures that float gracefully through the water. They come in many shapes and sizes, some being very small while others can be quite large. Jellyfish have a soft body and are mostly made of water. They do not have a brain, heart, or bones, yet they have been around for millions of years. Jellyfish can be found in oceans all over the world, from the surface to the deep sea.
One of the most interesting facts about jellyfish is how they move. They use their bell-shaped top, called the bell, to push water downwards, allowing them to propel themselves upwards. Some jellyfish also have tentacles that can sting their prey, which includes small fish and plankton. Their unique way of gliding through the water makes them one of the most captivating marine animals.
