Jellyfish: The Ancient Swimmers of the Ocean
Jellyfish are amazing animals. They have been swimming in the ocean for millions of years, even before the dinosaurs roamed the earth. They have soft bodies and long, thin tentacles. But did you know they don't have a brain or a heart? But somehow, they survive just fine! Jellyfish move by pulsing their bell-shaped body, kind of like a little umbrella opening and closing. They eat tiny fish and plankton. They catch their food by stinging it with their tentacles. It's their way of fishing! Even though jellyfish are beautiful, it's better to admire them from afar. Some of their stings can be harmful to people. So, remember, if you see a jellyfish while swimming, give it some room!
