Bulb Zone

The Koosh Zone is a unique type of biome in Subnautica.

It shares borders with one of the Mushroom Forest, Crash Zone and the Mountains. It also borders the Void that is located northeast of  Lifepod 5.

Description
The Koosh Zone is characterized by small crevices and overhangs in a sandy dune-like area. It is also abundant with small brown algae and a large variety of plants with blueish purple hues, the most notable of which being the  Koosh Bush.

The Koosh Zone is home to certain dangerous fauna. Notable predators, such as Shockers and, especially, Bone Sharks, can be found in great numbers throughout the Koosh Zone.

Shale chunks  can be found in the Koosh Zone.

There is a cave system located below the Koosh Zone, known as the Koosh Zone Caves. These caves are accessible via any of the three entrances located within the biome.

Several  Lava Geyser s can be found in this biome. This, together with the Koosh Zone Caves, suggests a small amount of volcanic activity in the Koosh Zone.

Wreck 3 is located within the Koosh Zone, containing several fragments.
