The Moon Jellyfish, scientifically known as *Aurelia aurita*, is a common species of jellyfish found in oceans worldwide. They are easily recognizable by their translucent, bell-shaped bodies, which can reach up to 40 centimeters in diameter. Moon jellyfish have long, trailing tentacles that contain specialized cells called nematocysts, used for capturing prey and defense. These jellyfish primarily feed on small plankton and fish larvae, using their tentacles to trap food. They are typically found in coastal waters and can often be seen floating near the surface. Moon jellyfish are harmless to humans, although their stings can cause mild irritation in some cases.
