It just emitted a sonic pulse. My Seamoth's hull integrity dropped to 60%. I'm backing away slowly. Note to self: Do not use sonar. Do not use lights. They are attracted to electromagnetic fields.
Correction: There are many things moving.
I thought the Floating Islands were dangerous. I thought the Mushroom Forest was a maze. But this... this is something else. I followed a geological signal from the radio tower—a low-frequency hum that didn't match the usual volcanic tremors.

They look like Crabsquids, but their heads are elongated. Translucent. I can see smaller organisms swimming inside their skulls. A symbiotic hive mind. The PDA has no data on this species. I'm naming it: Umbracephalus trenchalis .
Hypothesis: The precursors experimented here. They didn't just study the Sea Emperor. They tried to hybridize it. Whatever grew in this trench... it didn't survive. But its immune response did. The entire trench floor is covered in a gel that neutralizes small infections on contact. If I could synthesize this... Note to self: Do not use sonar
Given that "71288" does not correspond to a standard in-game item, blueprint, or coordinate in Subnautica , it is treated here as a —a distress call or a research memo from a survivor on Planet 4546B.
