Shelldiver Jellyfish Guide: Capture, Sell, and Reinvest

What do jellyfish do in Shelldiver?

Official descriptions identify jellyfish as the primary resource in Shelldiver. The turtle pursues and captures them with a bubble gun, then sells them in a small shop. More collecting supports more money to reinvest in the business and later dives.

The official Steam page names electric jellyfish, mutant amalgamations, and nearby-exploding “hellish” jellyfish as examples. Those examples confirm variety; they do not provide a complete catalog or a rarity ranking.

What is the safe capture-and-sale plan?

Use the source-supported loop rather than a made-up route:

1. Explore the currently available underwater area.
2. Chase and capture jellyfish with the bubble gun.
3. Return to the shop loop and sell the captured jellyfish.
4. Put the resulting money toward the documented equipment, shop, or skill priorities visible in the current game.

For the larger progression picture, read the official overview and the submarine and tools guide. The skill-tree guide helps turn a chosen priority into a cautious perk decision.

What is not documented publicly?

The checked official pages do not publish a complete jellyfish list, spawn locations, sale values, capture timing, rarity percentages, respawn rules, or a best farming route. This guide intentionally does not guess at any of them.

Question	Current answer
Are there multiple jellyfish types?	Yes; official descriptions name several examples.
Where does each type appear?	Not documented in the checked official sources.
What does each type sell for?	Not documented in the checked official sources.
Which type is best to farm?	Cannot be concluded without versioned, reproducible evidence.

How should you use field notes?

When the game itself displays a type, location, or value, record the game version and the exact screen context before treating it as a guide fact. Keep player observations distinct from the official claims above. This protects the depths and biomes guide from turning a one-off observation into a permanent map claim.
