Jellyfish have no right or left side—only a top and bottom—as they are symmetrical around a central axis that runs the length of their bodies.
3. Jellyfish are a boon to cancer research.
Green fluorescent proteins (GFPs) from the Aequorea victoria jellyfish species have transformed bio-medical research. The glow-in-the-dark proteins can illuminate specific proteins within the human body to track microscopic activity (for instance, cancer growth).
