Jellyfish are small aquatic mobs that poison the player when touched.

Spawning[edit | edit source]

Jellyfish spawn in ocean, deep ocean, frozen ocean, river and frozen river biomes.

Appearance[edit | edit source]

Jellyfish spawn with one of five different colors: light orange, purple-grey, light blue, green, and orange-red. There are also seven other colors, but jellyfish with these colors do not spawn naturally, and cannot be spawned with the jellyfish spawn egg. These include blue, orange-yellow, pale pink, pinkish-purple, speckled blue, and white.

Drops[edit | edit source]

Jellyfish will drop 0–2 slimeballs upon death. This can be increased with the Looting enchantment. They drop 1–3 experience when killed by a player or tamed wolf.

Behavior[edit | edit source]

A jellyfish swiming underwater.

Jellyfish are passive mobs, and will not attack or chase after you. They are translucent, and move in a pulsating manner. They are also luminescent at night. It takes about 6 seconds before jellyfish take damage when exposed to land.

If the player gets too close to a jellyfish, they will be inflicted with the Poison I effect for five seconds on Easy or higher difficulty. This does not, however, apply to tamed jellyfish.

Taming[edit | edit source]

A jellyfish can be tamed by using a fish net on it and then releasing it again. When a jellyfish has been released from a fish net, the naming screen will appear. A tamed jellyfish cannot be healed by 'feeding' it with food items, they can only be healed with a splash potion of Healing. Tamed jellyfish will not poison the player when touched.

Trivia[edit | edit source]

  • When jellyfish models were revamped, there were seven other models that were implemented, but never used. The missing jellyfish textures can be found in the mod files.
    • Despite these models being missing, jellyfish can still be spawned with these models with the summon command.
  • Jellyfish are the only passive mobs that poison the player.
