The Sparse Reef is a biome located southwest of Lifepod 5, bordering one of the Grassy Plateaus, the Blood Kelp Trench, the Sea Treader's Path and the Grand Reef. As its name implies, this area is very sparse and is home to a few types of small fauna and flora.

It also houses its own cave system, the Deep Sparse Reef. It can be found near the wreck in this biome.


The Sparse Reef is composed of relatively flat areas covered by green mounds scattered with Table Coral as well as large fissures where most of the Bioluminescent flora inhabit, notably the Eye Stalks.

There are also spire-like structures found along the border of the Sparse Reef next to the Grassy Plateaus, and near the Grand Reef. Found within these spires is a small entrance to the Grand Reef Caves, towards the Southeast.

The dangers in the Sparse Reef are Tiger Plants which are found in the deeper parts of the biome.

Spoiler alert: The following section contains story related material.

An Alien Vent Entrance Point and a Sanctuary Cache are found in the Deep Sparse Reef. Lifepod 19 is also found in the deep area of this biome.
