Space monster species: Ship Devouring Organism (SDO)
The Greegrox are getting a redesign, but I thought it would be a waste to just abandon their old design. So I thought why not use it for a different species? Thus I came up with a non-sapient, that means you can't talk to them, species that lives in space and likes to eat asteroids and other space debris, included wreckages of space ships.
Name: Ship Devouring Organism, SDO for short
System: NA, congregate in asteroid fields and around space ship wrecks

Not-Greegrox
Background
Sometimes space ships crash on the Ancient One for various reasons, suicidal overconfidence or piloting under influence are a few examples, a tiny species of organisms that inhabit the living moon have adapted to consuming the materials the space ships are made out of.
The Scryve took an interest in these small creatures and begun studying them. And eventually someone came up with the idea to weaponize them, thus the project Ship Devouring Organism was born. The creatures were made larger so they could devour ships easier. Augments were installed in the test specimens in order to control them.
The field tests went great, the Ship Devouring Organisms, or SDO for short, were deployed upon the ships of a rather unruly ward species and although they suffered losses they ultimately prevailed. Satisfied the Scryve forces left, however some of the SDO left behind were not entirely dead and regained their health by consuming the wreckages left after the battle.
Left to their own devices the SDO multiplied, the resulting offspring did not posses control implants putting them beyond the reach of the Scryve.
Meanwhile Scryve encountered the problem of what to do with the SDO when there is no war, thus nothing to feed them with. While the idea of feeding them trash was entertained, they finally decided to only deploy SDO under times of war and all existing SDO specimens where euthanized.
By the time the Scryve discovered the SDO they had spread far and wide and it was deemed too costly to hunt them all down.
Ship
Primary attack - launches a ball of acid that if it hits a ship produces damage over time
Secondary attack - devours debris and replenish crew bar
Player interaction
Wild SDO will attack the player on sight, they aren't mean, just hungry.
A few might be encountered alongside Scryve battleships.
There could be a quest of procuring the knowledge of their creation from the Scryve which would allow to player to grow their own SDO.
Have I ever mentioned I hate coming up with names?
