A tharul was an lifeform, a type of animal that was native to the worlds of the Cardassian Union. A tharul usually had a very low viewpoint on situations, living very close to the ground in comparison to larger humanoids. In the language of the Cardassians, a "tharul's-eye view" was idiomatic, referring to a viewpoint looking up from the floor.
In the 2330s, Corbin Entek thought of that idiom while viewing recordings taken from a visual transmitter placed on the floor of Captain Vance Haden's ready room. (TLE novel: The Art of the Impossible)
