The Red Jellyfish is a jellyfish in Hungry Shark World. They have an extremely painful stun that drain a lot health, and they can kill an XL shark with one sting. They spawn in every map at long survival time or deep ocean level.
Red Jellyfish do not move, but rather do somehow very slow.
Red Jellyfish is the second most strongest jellyfish, and can only be eaten by sharks in Mega Gold Rush, or if they have the Hungry Letters collected. However, they can be eaten by the Atomic Shark and the Meltdown Shark without Mega Gold Rush or Hungry Letters.
