The world's largest animal is not actually a blue whale, but a living jellyfish.
This jellyfish, called "lion's mane jellyfish", also known as "sarka anemone", is a sea anemone jellyfish found in the deep seas of all oceans around the world. It can reach a length of 120 meters and weigh about 100 tons, which is longer than the body length of a blue whale. However, because its body is fragile and not easy to detect, few people know about this fact.
The lion's mane jellyfish has a funnel-shaped body with 8 long tentacles on its head and thousands of spiny-like cells on the tentacles, which can quickly catch tiny creatures in seawater and is an efficient predator. Its body is made up of hundreds of transparent "necks", each with thousands of cells that can carry out autonomous activities and breathe and digest through these cells.
Lion's mane jellyfish have a short lifespan of only a few months, making them difficult to observe by humans. They usually float in the deep sea, but are sometimes washed up by the tide to the shore and become a mysterious and beautiful landscape.
In addition to the lion's mane jellyfish, there are many peculiar creatures in the world, such as "hot spring bugs", "water bears", "sea urchin worms", etc. These creatures have a miraculous ability to adapt and can survive in extreme environments. For example, hot spring insects can live in spring water with temperatures of up to 80°C, water bears can survive in extreme drought and cold conditions, and sea urchin insects can survive at depths of more than 10 kilometers under the sea.
Although unknown to the general public, these creatures are among the most mysterious and wonderful life forms on Earth. Their existence not only provides evidence for the diversity of life, but also sheds light on our exploration of the universe and the origin of life.
