Subnautica 2 Hycean

Jelly · Multiple Biomes · Subnautica 2 current build

Overview

A large translucent jelly organism with a broad bell and trailing stinger filaments that extend up to 6 metres behind its body. The Hycean is not an active predator — it drifts passively in current corridors, and the filaments cause toxic contact damage to anything that swims into them. Pioneer suits provide partial protection; sustained contact causes increasingly serious debuffs.

Subnautica 2 Hycean — Behavior

Entirely passive — drifts with ocean current and does not respond to Pioneer presence. Hazard is purely from incidental contact with trailing filaments. The gap between bell and filament tip is much larger than a casual glance suggests.

Subnautica 2 Scan Data

Jelly organism — trailing stinger filaments confirmed; contact toxin rated moderate. Passive movement only; no active prey tracking. Distribution: current corridor concentration zones, especially near biome boundary transitions. Filament trailing distance: up to 6m behind bell body.

⚡ Subnautica 2 Hycean — Survival Tips

  • Clear the TRAILING EDGE — filaments extend 4–6m behind the bell body. Many contact incidents happen from swimmers who cleared the bell but swam straight into the trailing filaments.
  • Current corridors concentrate Hycean density; reduce speed and maintain visual tracking when transiting these zones.
