Cave Jurgoran

Though not limited exclusively to caves, this subspecies of jurgoran is usually found in environments with little-to-no natural light. In order to adapt to its dark surroundings, the cave jurgoran has developed bioluminescent scales and a reflective hide. Each creature has a distinct glow pattern, nearly undetectable to most, but instantly recognizable by other cave jurgorans.

It is currently unknown how the jurgoran managed to migrate out of Dromund Kaas and settle in the darker corners of the galaxy. The most common theory among biologists is that the early Sith used jurgorans in battle but found them unpredictable and deserted them like forgotten pets. If this theory is correct, the cave jurgorans of today are descendants of these abandoned tools of war. (Codex Text - Star Wars the Old Republic / SWTOR)
