Jellyfish are soft, gelatinous marine animals found in oceans worldwide. They belong to the phylum Cnidaria, which also includes corals and sea anemones. Jellyfish have a distinctive umbrella-shaped bell and tentacles that can sting, used for catching prey and defense. They mostly drift with ocean currents and feed on small fish, plankton, and other marine organisms. Although they are ancient creatures, dating back over 500 million years, they play a crucial role in marine ecosystems. Some species can be bioluminescent, glowing in the dark, while others can reproduce both sexually and asexually, showcasing their adaptability.
