Grand Reef

The Grand Reef is a unique deep biome in Subnautica that covers the southwestern portion of the map.

Description
The Grand Reef is home to many types of fauna, including the large herbivore Sea Treader. It is also known for its unique types of flora, from the luminous Floating Stones to the peculiar Membrain Trees.

Below this area, the player can find a large cavern system featuring the same type of flora and fauna, with the addition of Crabsquids and Jellyrays.

Commonly found harvesting nodes in the Grand Reef are basalt outcrops, as well as many other type of rare crystals.

Scattered deep within the area are many hydrothermal vents.

Trivia

 * In earlier builds, the Grand Reef had large pillar-like spikes, some of which were visible above the surface. However, these were removed, and was explained to be temporary.
 * Certain structures have curious house-like caverns, very reminiscent of grotto-homes in primitive cultures.
