Ear jellyfish
Aurelia aurita
Did you know?
- For over 500 million years, jellyfish have been drifting through the world’s oceans at speeds of up to 10 km/h. By contracting their bellies, jellyfish expel water and propel themselves forward using the principle of thrust. Most of the time, however, they simply let themselves be carried along by ocean currents.
- The jellyfish life cycle begins with tiny eggs that develop into larvae (planulae), which drift through the water until they settle on the seafloor and become polyps. Through budding, the tube-shaped polyps give rise to sac-like ephyra, which eventually grow into free-swimming medusae and continue the cycle through reproduction.
- The ear jellyfish is found in all the world’s oceans and is characterized by four rings in the center of its bell. These are the jellyfish’s reproductive organs. Those of the females are reddish-purple, and those of the males are white to orange.
- Ear jellyfish possess a mild stinging toxin. However, since the jellyfish’s stinging cells cannot penetrate human skin, it poses no danger to humans.
