Jelly Lei Creature Guide and Details | Subnautica 2

Hangs off the large structures.

Anthobrachia hebesoros, the young stack of flower arms. Reproductive stage of a flower-like jelly.

[1] Polyp
Despite its resemblance to a kelp, the jelly lei prefers to underneath surfaces - where it cannot photosynthesize. It is the rooted polyp phase of a jellyfish's life cycle. The chain of 'flowers' growing beneath the polyp are larval jellyfish, called ephyra. The stalk itself is called a scyphistome.

[2] Ephyral traits
The budding larvae have broad, flat petals which will eventually merge into the adult jelly's bell. These petals already host photosynthetic symbiotes - it is possible the adult jelly will seek light sources to grow, akin to the terrestrial upside-down jelly. Note the purple color produced by photosynthetic retinal, the same molecule your eyes use to detect light.

[3] Heat stress
The jelly lei's growth cycle has been accelerated by heat stress. The stalked parent may release its larvae early to allow them to swim clear of hot, oxygen-depleted water.
