Jellyfish Swim by Jet Propulsion, No Brain Needed

Original: Watch a jellyfish swim: it squeezes its bell to jet water backward — no brain, no heart, no bones, just physics. Jellyfi

Jellyfish move through the ocean by squeezing their bell to jet water backward, a form of propulsion that requires no brain, heart, or bones. The animals are up to 95% water and have pulsed through the seas for more than 650 million years, outliving the dinosaurs and the first forests. Science communicators are highlighting the creature as a striking example of physics and evolution working together.

Why now: The striking simplicity of jellyfish anatomy and their ancient survival story is capturing public fascination on science-focused feeds.
