MOON JELLYFISH
DESCRIPTION
Also called Aurelia, the Moon Jellyfish is a gelatinous marine animal known for its distinctive bell-shaped, translucent body that can reach up to 40 cm in diameter. Its body is often adorned with four distinct, horse-shoe shaped gonads that are visible through the bell, giving it a unique appearance. Moon Jellyfish are typically found drifting in coastal waters and are known for their gentle, pulsating movements as they propel themselves through the water using rhythmic contractions.
FUN FACTS
- Moon Jellyfish have been around for over 500 million years, making them one of the oldest living creatures on Earth
- They are also bioluminescent, meaning they can produce light, which can be seen when they are disturbed in the water.|Despite their delicate appearance, Moon Jellyfish can survive in a wide range of salinity levels and temperatures, allowing them to thrive in various marine environments
