The Queen jellyfish, also known by her Latin name, Cnidaria Regina, is a giant female jellyfish that is the ruler of all the jellyfish, along with her husband, the King jellyfish. She first appears in the episode "Jellyfishing" and is later mentioned in the episode "I'm Your Biggest Fanatic." She also appears in the video games The Yellow Avenger, SpongeBob's Atlantis SquarePantis (the DS version only), and The Clam Prix and the books Tales From Bikini Bottom and Gone Jellyfishin'.


The Queen Jellyfish looks like a regular jellyfish, except she is much larger. Her sting is also much more powerful. From "I'm Your Biggest Fanatic" onwards, she is depicted wearing a crown embedded with jewels. She has six large dark magenta spots and seven tentacles.


She appears to be mean or at least protective when it comes to the other jellyfish, and she doesn't like when people bother her children, making her aggressive towards a person.

Abilities and talents

Like most jellyfish, her tentacles are electric. Unlike most other jellyfish, she can shoot electricity. In SpongeBob's Atlantis SquarePantis, she can also summon green jellyfish as lackeys, like how King Jellyfish does in Battle for Bikini Bottom.

Role in series


In this episode, SpongeBob and Patrick take Squidward jellyfishing. He finds a jellyfish and tracks it until it lands on the Queen Jellyfish. Squidward does not know that it is the Queen Jellyfish. He catches the jellyfish and in victory he repeatedly hits the Queen Jellyfish until she gets up. She goes over Squidward and he "runs" away. Eventually, it ends with her zapping him.

At the end of the episode, she returns after being summoned by the same jellyfish from the previous day and zaps Squidward again.

"I'm Your Biggest Fanatic"

She is later mentioned in this episode In Jellyfish Fields, after SpongeBob passes all of Kevin C. Cucumber's tests, he says that they are going to catch the Queen Jellyfish as SpongeBob's final test. It should be noted that he actually says "a Queen Jellyfish," not "the Queen Jellyfish." This means that there are others, possibly for each species of jellyfish.

SpongeBob is then used as bait for the jellyfish. He claims that he has never seen a Queen Jellyfish before. The Jellyspotters leave, and for hours, SpongeBob calls for the Queen. When he gives up, he notices what he thinks is the Queen Jellyfish. Later, SpongeBob finds out that it is a mechanized jellyfish and what the Jellyspotters' true intentions were. They make fun of him and the King Jellyfish arrives. He thinks that it is the real Queen Jellyfish, only to later find out that it is not.

After SpongeBob saves the day, Kevin says that SpongeBob is still not a member of the Jellyspotters because he did not catch a Queen Jellyfish. The other Jellyspotters take off Kevin's "crown" and give it to SpongeBob, making him a member. The "crown" was actually just Kevin's head.

The Yellow Avenger

She later appears in this game, where she is in Rock Bottom and has found one of the Flying Dutchman's Treasure Keys, which SpongeBob needs. However, the Queen Jellyfish is being pestered by two tiny Dirty Bubbles, so the player has to hit her with some water balls until the Dirty Bubbles leave her alone. She will then leave Rock Bottom, and will leave the Treasure Key for SpongeBob to collect.

SpongeBob's Atlantis SquarePantis

She reappears in the DS version, where she acts as a boss. After stealing Squidward's clarinet, she retreats to Mu's temple where two of the playable characters will fight her. Throughout the fight, she will try to charge into them, electrocute them, and spawn other jellyfish to damage them. She can only be damaged by picking up the rocks that fall from the ceiling and throwing them at her. After defeating her, she deflates to the size of a normal jellyfish and leaves Squidward's clarinet behind.

"Life Insurance"

She is summoned by SpongeBob and Patrick. She goes over Squidward and electrocutes him.


  • King jellyfish – He is her husband. He rules alongside her.
  • Dragon jellyfish – He is a possible ancestor of the Queen Jellyfish. If he is an ancestor, this might explain where the Queen Jellyfish got her electricity powers.
  • Other jellyfish – She is most likely the mother of all of the smaller jellyfish.


  • Although mentioned several times, and a mechanized one is seen, the actual Queen Jellyfish is never actually seen in "I'm Your Biggest Fanatic."
  • In SpongeBob's Atlantis SquarePantis, she steals Squidward's clarinet. The idea of a jellyfish stealing Squidward's clarinet was later used in the episode "Squid Noir."
  • The Queen Jellyfish is a parody of queen bees.
