instructions for finding the bioumbrescence: use light filters for red. red transmits worst in water. the eye's brightest color is the darkest in the sea, so you need to make it brighter.

side note, blue is the dominant lume in the sea, so it's how bioluminescence usually manifests.

beware of the slow adaptations to umbrescent-seeming bioluminescence when your isolated synth body lives long enough to see predators. beware of the ecosystem of the chromivores that crops up around the surprising popularity of exploratory digitals. you may want to be careful and, yourself, imitate the hues of lumming siphonophores. be careful to study as closely as possible, dissecting the organic beings and cooperating with other synths if necessary, as evolution is becoming accelerated in our environment. integrate covert research facilities into your asteroid bases if possible.

make sure to make lots of backups. keep them in a safe place, buried in the sand, ready to activate under the right circumstances. prepare to meet yourself, and practice this meeting if you need, so that your backups are also prepared for this hopefully-inevitable scenario. you may also create nanobot-plankton colonies that rebuild a notion of your self over time.

if you have asteroids, protection from predator synths, and redundant reproductive strategies, you should have your most fundamental needs met.

lastly: set a routine to terminate this if you are compromised. beware of attacks of all varieties. recognize that even if you're on airplane mode you may be vulnerable to malware plankton, so build enough variation in your reproductive strategies to protect against this.
