A Thargoid Hydra Tissue Sample is a sample of the hull of a Thargoid Interceptor Hydra Variant that has been extracted by a Research Limpet. The sample is corrosive to ship modules, and can only be safely transported using a Corrosion Resistant Cargo Rack. It is considered an illegal salvage item in most systems.
A sample of bio-mechanical tissue from a Thargoid Interceptor-class vessel. This sample is from the Hydra variant, and is therefore more developed than samples from other kinds of Interceptor, with denser biological matter and more intricate technological elements. Such samples are highly sought after by scientists despite being highly corrosive.
