Fiction:Excation empire

The Exacation are a race of extragalactic aliens, with a proto plasmic outer skin and a liquid interior. they have been sighted around the edges of the galaxy nonourose times.

Biolagy
The Excation biolagy is very simeler to an oversized cell, however there are noticable diferences, firstly the outer 'skin' is non-permiable, the Excation's interior liquid can replace lost or damaged parts of the body very quickly and the locamotion system is reliant on fluid presure.

activity
the Excation have very small fleats of ships, or rarely one large 'home ship'. If the ships find a planet inhabeted by a tecnologicaly advanced race, they will digorge the waiting excation onto the planet and abduct the population and take it technolagy. How they find Inhabited worlds is unknows but it is asumed they use agents, or lesser specise to find the creatures.
