Jellyfish are one of the oldest creatures on Earth, having existed for about 500 million years. Their bodies are 95% water, and they are unique creatures that live without a brain.
Recently, the number of jellyfish has increased worldwide due to climate change. Some countries use jellyfish for food, and they have long been considered a health food in East Asia. Modern scientists are using the bioluminescent abilities of jellyfish in medical research.
