Just my twopence...
Probably been covered by others in this crazy thread-nought but I thought I would get it out there anyway...
The purpose of all life-forms is to survive, to survive life needs to reproduce.
These life-forms were given the name barnacles for a reason. They are going to be somewhat similar to our Earth barnacles. Otherwise you might as well have just called them Kangaroos or Limpets for a more reasonable simile.
That being said it is likely that these alien ‘barnacles’ are living and feeding, and ultimately reproducing. I propose therefore that:
The ‘barnacles’ reside in Nebulae and feed off the ionised gasses contained therein. This would also lead to them only being found on non-atmospheric planetoids as an atmosphere would likely prevent them feeding.
The adult ‘barnacle will attach itself to a substrate and develop six hard plates to surround and protect their bodies. They may have legs of some sort that they can use to feed off the surrounding gasses. There may be a possibility that we could provide the barnacle with its food source, artificially, in order to see these legs.
The protrusions surrounding the barnacle I would hypothesise are its reproductive organs and as such the green glowing buds are actually the barnacles offspring. If left for long enough they will burst open to produce larvae (possibly UAs?). Or alternatively these buds could be seeds, however due to gravity it would be near impossible for the seeds to leave the planets surface.
Earth barnacles are hermaphroditic and produce eggs that hatch. There are then a further 2 larval stages. An initial simple larvae form with one eye, head and telson(body/tail/back bit ). Sounds similar to UAs…
A second (Cyprid) larval stage where its sole purpose is to find a suitable home. Possibly also UA connection.
This leads to my conclusions…
- They are an alien life form surviving in the sea of space. Possibly placed here to farm or naturally reproducing and travelling via a larval stage.
- The green pods are eggs growing on the end of the reproductive system of the barnacle.
- The UAs are possibly (one) stage of the larval growth of the barnacles.
One thing that didn't take into account is the marking found on all barnacles being identical and present.
Evolution, though appearing sometimes magical, is unlikely to create a species that has an exact identical marking on an apparently crustaceous shell. Over time there would be a observable difference between these markings which we are not seeing. On top of this we 'know'
I'm afraid not - the nebula that they can be found in relates to their origin and I can't talk about that.

This could suggest that barnacles found in other nebula may have a different origin.
I propose that the marking is a 'brand' placed there by an intelligent life-form. One that can travel large interstellar distance in a single bound. And that this species has several location they might call home. Each farmer colony would have a different 'brand' that would identify where they originate from within there species.
A further question arises to the placement of some of the barnacles near crash sites. Did someone already know about the 'seeds' or larvae. Were they transporting these larvae that degraded their ship enough to crash land on a planet and the surviving larvae grew and attached itself to the planet close to the crash site (or were they shot down in transport as they stole the property). If this were so then the barnacle must have been found at a later date by the intelligent life-form in order to be branded.
Hopefully the research station will be built soon and we can find out some more by employing the great human research method of destroy and dissect.
