Let's talk aliens.

[Tenacity]

If a nomad were to somehow be 'captured' while still alive, it could simply terminate it's own form. Each nomad 'ship' is nothing more than a limb, a finger or a thumb or an arm, of a particular nomad entity. Some nomad entities within the mindshare can control a dozen or more 'limbs' at once. Whenever a particular nomad ship dies or is destroyed, any knowledge or experience that it had gained up to the point of death is 'saved' to the mindshare, and a new form can be grown to replace it.

Because of this, nomads are for all intents and purposes immortal. Killing a nomad ship doesnt kill the nomad itself, because the intelligence behind that ship is basically saved to the mindshare 'hard drive' and can be loaded into another ship once one is grown or made available.

So, even if you managed to cut off it's connection to the mindshare, everything it knew up to that point will already have been recorded/saved within the mindshare, and the entity can simply disable or kill off that particular limb. The nomad 'ship' that you captured would become inactive/dead, and you would gain nothing from it.
