Jellyray

The Jellyray is a large, peaceful ray-like creature that drifts through the glowing Jellyshroom Caves of Subnautica 2. Its broad, translucent body is laced with bioluminescent veins that pulse with soft cyan and purple light, creating a mesmerizing display as it glides through the already-glowing cave systems. The Jellyray feeds on the bioluminescent fungi that line the cave walls, absorbing their light-producing compounds into its own tissue — a remarkable example of biological piggybacking that makes the creature itself glow. Despite its size, the Jellyray is entirely docile and will not react aggressively to players, simply drifting away if approached too closely. It is one of the most beautiful and tranquil creatures in the game, and observing a Jellyray gliding through a glowing Jellyshroom Cave is one of the most memorable sights in Subnautica 2.

Jellyrays are found exclusively in the Jellyshroom Caves at 150-300m depth. They drift through the glowing cave systems, feeding on bioluminescent fungi along the cave walls. They prefer the larger, more open chambers of the cave system where they have room to glide, and are most commonly found near clusters of Jellyshrooms — the large, glowing mushroom-like formations that give the caves their name.

The Jellyray is completely harmless and has no combat behavior whatsoever. It is a passive drifter that glides slowly through the Jellyshroom Caves, feeding on bioluminescent fungi along the cave walls. If approached too closely, it will gently drift away rather than fleeing or attacking. It has no defensive abilities, no weapons, and cannot damage the player under any circumstances. No combat strategy is needed — the Jellyray is purely a creature to observe and enjoy. The only risk associated with Jellyrays is becoming so absorbed in watching their bioluminescent display that you lose track of your oxygen supply in the caves.

If caught, the Jellyray yields Bioluminescent Tissue, a material that can be used in specialized crafting recipes involving light production and biochemistry. It can also be cooked for a modest food value, though its bioluminescent tissue makes it less nutritious than standard food fish. The tissue is primarily used for crafting light-emitting base decorations and specialized scanner upgrades.
