The astroplanktonic re-no wait, wrong page, ahem. As nanosophont infrastructure improved, it was inevitable that something outwardly dumb would arise as a consequence of them trying to move up the food chain, and thus the somewhat inaccurately named astroplankton would arise. Propelling themselves along with gas and pellets and scooping up different types of organic matter. Perhaps the most notable difference between astroplankton and old nanosophont spaceships is the development of an eye, here the astroplanktids (the name for the nanosophonts inside) inside gather melanin in their cells and report back constantly to the main ship on what they’re picking up from outside, allowing basic decisions to be made to avoid crashes and find food. Whilst the cells inside are autotrophic, the ship itself needs materials to be built and maintained, and thus they hunt down appropriate items such as space dust, other microbes, flora, and more to find materials. Perhaps the most impressive of such species is the specialist F.simplecticus, it is the smallest of the genus and subsists entirely off of cardboard, primarily in box form, which the astroplanktids inside re-secrete to form the ship, F.simplecticus is often used as a model organism for studies on astroplankton, mostly because the organisms committing those studies have no clue it’s actually intelligent. Indeed, as a consequence of all their cells being brain cells with sophontic capabilities on their own, whilst their actions are simple and predeterminable on a macroscopic level, not only can they learn alarmingly fast, but on a microscopic level it is indeed basically a miniature spaceship being run. All astroplankton have a double airlock for a jaw to allow intake of food without the inhabitants or their atmosphere being sucked out. Meanwhile on the other end they expel gas, typically with the help of a small pellet secreted by the inhabitants, to produce thrust.
