"I caught a jellyfish! I wonder how it would taste on some toast..." —Animal Crossing

The moon jellyfish is a unique benthic creature introduced in New HorizonsDiving is the only way it can be obtained. In previous games, the jellyfish was obtained by fishing from Animal Forest+ to City Folk (August 16 - 31st), and was once tied with the tadpole as the lowest selling fish in the Animal Crossing series, at 100 Bells. In New Leaf, it is an obstacle the player must avoid whilst swimming in the ocean.

Donation to the museum[]

In New Horizons[]

Upon donation or selecting "Tell me more about this!", Blathers the curator will say:

"Ah, the moon jellyfish...what's not to love about this pretty floating flower of the sea... Well, I suppose its tentacles do give a sting when touched...but it's only a mild thing to the likes of us. Other creatures may not be so fond of this translucent beauty. Though who can blame them, really? Moon jellyfish have stinging cells called cnidocytes that kill fish and other small critters that float by. And they use their "oral arms" to pull these morsels into their mouths and stomachs. Indeed, one need but observe the moon jellyfish to see how brutal AND beautiful nature can be."

Further Information[]


One of the many types of jellyfish called a moon jellyfish.

Main article: Aurelia aurita on Wikipedia

Jellyfish are of the Cnidaria, a group of early life forms that also includes corals and crinoids. Cnidarians consist of two main "forms": polyps and medusa. The medusa strain is a single polyp that has adapted to float upside-down; these are jellyfish. When jellyfish are born they first stick to coral or other surfaces and as they grow they detach and assimilate into plankton where they grow into their adult stage.

Moon jellyfish feed on smaller organisms such as mollusks, crustaceans, bristle worms, mobile algae, fish eggs, and occasionally gelatinous zooplankton. Both the adult medusae and larvae of Aurelia have cnidocytes to not only capture prey but to also protect themselves from predators (including the ocean sunfish and leatherback sea turtle). This common and widespread species of jellyfish is quite distinctive due to the clover-leaf pattern on the top of its bell formed by gonads.
