Extracted with Unity Asset Explorer The Shadow Leviathan is a 60+ meter long Leviathan Class organism that can be found exclusively in large caves of Sector Zero of 4546B. It has a large triangular head with 3 eyes on each side, and a mouth lies underneath the head, which is bioluminescent and blue. The mouth is long, and also has many long, blue teeth. The shadow leviathan is a very oppritunistic hunter, going for any large prey, presumably because of the lack of any of large animals in the Crystal Caves and Fabricator Caverns. The few animals even there are small fish and bacteria, which is hupothesized to also feed the shadow leviathan's massive appetite. It is capable of nearly destroying a seatruck or prawn suit before letting go of you with its large mantis-like arms. It has a long eel-like body to easily move around large crystal formations.
