The egg-yolk jellyfish is a very large jellyfish with a bright yellow centre that looks like a fried egg. It lives in cool seas across most of the world's oceans and is most common in the Northern Pacific. It is special because it can grow very large, and it is one of the few jellyfish that can survive in low-oxygen water.1
