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 currently 5 Jellyfish variants, 3 of which only appear during Hardmode.
In Expert Mode, Jellyfish will periodically become electrified, making them invincible for the duration of the attack. A Jellyfish will constantly maintain its speed while electrified unless it comes into contact with a wall or the water's surface. If the player attacks a Jellyfish with a sword while it is electrified (or any other swung item that deals direct damage, such as most tools), the player will be hurt by 1.3× contact damage of the Jellyfish.[1] This also applies to projectile contact weapons (Spears, Shortswords, Solar Eruption, Sleepy Octopod, Sky Dragon's Fury, and Whips).

Notes
- 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.
Trivia
Bestiary entries
- Blue, Pink and Green Jellyfish: "That strange tingling sensation in the water may be the unwelcome surging of electrical death from a brainless jellyfish. Swim with care."
- Blood Jelly: "Jellyfish swimming in the bloody waters of the Crimson become infected, converting them to its all-consuming cause."
- Fungo Fish: "Some fish exposed to glowing mushroom spores become a curious mushroom-jellyfish hybrid, glowing softly in the watery depths."
