Jellyfish (Outer Wilds)

Jellyfish are large aquatic creatures that aren't hostile that are found in Giants Deep.

They are made extinct when their sun goes supernova

Anatomy
Fully aquatic, Jellyfish are almost identical to the creatures that live on Earth. They are orange and have long, oral tentacles surrounded by electrified tentacles. They live in the deep ocean in Giants Deep, and regularly pass through the electric field surrounding the core. This means they have to be immune to electricity to survive. They are hollow, and can be used by the player to reach the core of Giants Deep.

Nothing else is known about them.
