As those files said, " _...These Predators may mimic food or sexual partners to lure in their prey, one example is the Snapping turtle whose tongue resembles a worm it can wriggle around, if a fish attempt to eat it they will instead be eaten by the turtle, _*_another form of aggressive mimicry is found in..._* " And also this one " _Certain physical principles hold true across massive size differences and create illusions if similarity, a cell looks like a star in supernova, our eyes like a nebula, _*_what if these similarities applied to life at different scales as well?_* " Looks like it was those Mimicking Creature they trying to say. Also in 13:18 that is not a Planet but a *Dead Egg* and in 14:17 that is An Egg that still alive, and inside thos Eggs are also Mimicking Creatures like in 21:07 soo..... Apparently there are Thousand of these out there.
One question. How do these things get nourishment consistently? Secondly. If it is primary diet is people, how slow is its metabolism and just how long can it go without food? Maybe I'm just thinking too deep on this ¯\_(ツ)_/¯
In the End, when you got grabbed by the those _Mimicking Giant Creature_ if you tries to run or move away the ship won't move because you're already got grabbed by those Creature.
the engines were shown previously to be unresponsive, meaning they were broken. the attack of the creature had expertly disabled them. therefore the protag was left utterly defenseless, to the point of being unable to run.
