Critter of the Week: Purple people eater jellyfish

Today (Nov 3) is World Jellyfish Day - a day to celebrate these remarkable sea creatures that have been around for around 500 million years and are older than the dinosaurs! The purple people eater jellyfish (also known as the night-light jellyfish and the mauve stinger) is a little jelly that packs a punch! It has stinging cells all over its body and has been known to wipe out entire fish farms.
