Blood Kelp Zone

The Blood Kelp Zone is a special biome in Subnautica characterized by a variety of giant Bloodvines, some of which carry Blood Oil pustules down near their stem.

Description
Both Blood Kelp Zones serve as entrances to the Lost River.

First Blood Kelp Zone
The first zone (aka Blood Kelp Trench) is located south-east from Lifepod 5, between the Dunes, the Sparse Reef, the Grand Reef and the Sea Treader's Path.

It consists of a single deep trench with natural rock bridges spanning from one wall to another, and a small cavern system located below the Bloodvines where their roots can be found. One of the wrecks can be found in this area, stuck between the trench's walls. This zone is nearly impossible to explore with the Cyclops due to the trench's narrow width.

Second Blood Kelp Zone
A second zone can be found to the north of Life Pod 5, in-between the Mushroom Forest and the Underwater Islands. This zone is considerably larger than the first one, albeit being more exposed to the surface and not as deep.

Unique to the Northern Blood Kelp Zone are Crabsquids, Uraninite Crystals, as well as small "underwater islands" supported by large Floaters and Blood Cave Roots.
