Subnautica 2 Aeroshell Sponge Creature Details

A glowing sponge (tentatively Symphon aeroshell ) that resembles the cone of a heat shield on atmospheric entry.

1. Predation strategy The aeroshell feeds on microorganisms attracted to light, especially in dark caves where it can be mistaken for the sun.

2. Light source Instead of relying on symbiotic bacteria, the aeroshell generates its own light through oxygen-fueled reactions. This light is piped throughout its tissue by glassy fibers resembling those grown by Earth's glassy sponges—among the longest living animals known.

3. Symbiotic partner Often found associated with shootroots (hard-surfaced starfish-like organisms that burrow into the seafloor). The exact dynamics of the symbiosis are unknown. Await further updates.

Assessment: useful light source in dark water. May provide interesting bio-optics reference.
