Kelp Root

The Arctic Kelp Roots are a flora species that dominate the Arctic Kelp Caves.

Despite their close proximity to the Arctic Kelp, their colouration would suggest that they are an entirely different species to the Kelp on the surface and are in fact closer related to Bloodroot.

Trivia
The Arctic Kelp Roots were created for the Kelp Forest of the first Subnautica, but were then re-skinned to become Bloodroot and never used for the Kelp Forest.
