Coral (similar to those on earth) are life forms found across Planet 4546B. Samples can be harvested from some of them using the Survival Knife or the Thermoblade, although most are unharvestable. With the exception of Brain Coral, no coral species can be planted and farmed.

Trivia

• Although coral and fauna are sorted separately in the PDA, coral on Earth are a type of fauna. Presumably the same is true on 4546B for the corals to be named as such.
