This article is about Table Coral Sample. You may be looking for Table Coral or Coral Tube Sample.

The Table Coral Sample is a raw material that can be harvested from Table Corals. Together with Copper Wire and Gold, they are used to manufacture the Computer Chip. This makes the Table Coral Sample a key-component to harvest early on in the game.

They cannot be harvested by hand. The player must use their Survival Knife in order to cut the Table Corals, causing the Disk to break and drop multiple Table Coral Samples.

There is no distinction between Table Coral Samples obtained from Green, Purple, Blue or Red Table Corals in the inventory. They will all display an orange Table Coral Sample.


If cut using a Survival Knife or Thermoblade, Table Corals will leave behind 2-5 samples that slowly drift towards the ground.

Data Bank Entry

Each disk is an individual colony of microorganisms, filtering nutrients from the water.

Growth patterns indicate the colonies are in direct competition for positions with superior current or light. Unlike other coral species its structure is malleable, softly pulsating as it pumps nutrients to its extremities, and only turning rigid when it senses physical assault.

The jewel-like nodes in the surface are concentrated build-ups of rare minerals the coral is unable to process.

Assessment: Exploitable in computer chip fabrication
