Jellyfish
Jellyfish are enemies found in water. When underwater, they attack by propelling themselves towards the player in short bursts. When outside of water, they will be unable to move or pursue the player in any way. Jellyfish are able to jump out of the water to attack players, often leaving them stranded on land. Most varieties of Jellyfish produce light, making them easy to spot in dark areas. There are 5 Jellyfish variants, 3 of which only appear during Hardmode.
In Expert Mode(Desktop, Console and Mobile versions), a Jellyfish will periodically become "electrified" (except for Fungo Fish). During this electrified state, it is invincible, and will constantly maintain its speed unless it comes into contact with a solid block or the water's surface. Certain attacks to Jellyfish in this state will hurt the player by 1.3× the contact damage of the Jellyfish (see Notes for details).

- Jellyfish Statues can be Wired to spawn Blue Jellyfish.
- If knocked out of water and onto dry blocks, Jellyfish are rendered immobile until knocked back into water, or water reaches them again. In Expert Mode, this will also prevent them from becoming electrified.
- Blue and Green Jellyfish are capable of spawning in the Underworld if there is a large enough body of water.

- Fungo Fish: "Some fish exposed to glowing mushroom spores become a curious mushroom-jellyfish hybrid, glowing softly in the watery depths."
