This article contains information that is updated for the latest Experimental Version of Subnautica. Players using stable mode may find this information inaccurate.

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, however. The player has to use their Survival Knife in order to cut the Table Corals, causing the Disk to break and drop a Table Coral Sample.

At the moment, there is no distinction between Table Coral Samples obtained from Green, Purple, Blue or Red Table Corals in the inventory. They will all show up as an orange Table Coral Sample in the inventory.


If cut using a Survival Knife, Table Corals leave behind a single Table Coral Sample that will drift to 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.
