Jellyfish are one of the oldest animals on Earth, with fossils dating back to over 500 million years ago. They don’t have a brain, heart, bones, or even a true digestive system. Their bodies are composed mainly of water. 

Jellyfish are fascinating creatures in the ocean. Their unique anatomy and behavior make them stand out among marine life. They have a gelatinous, umbrella-shaped bell and trailing tentacles equipped with stinging cells called nematocysts, which they use to capture prey and defend themselves. Jellyfish come in various shapes, sizes, and colors, from tiny species to large, majestic ones like the lion’s mane jellyfish. Despite their simplicity, jellyfish play important roles in marine ecosystems as both predators and prey, contributing to the balance of oceanic food webs.
