Biology and appearanceEdit
Growing many timers larger than an average dianoga, easily being able to dwarf a Human, the giant dianogas sported several barbed tentacles and a gaping maw lined with sharp teeth, not unlike that of a sarlacc creature. The creature possessed a giant red eyestalk which was about equal length to its tentacles.
Only one known specimen was recorded in galactic history. It inhabited the chamber of the sewers directly underneath the lobby of Black Sun leader Prince Xizor's palace on Imperial Center. In 4 ABY, when a Rebel Alliance team led by the renowned Rebel pilot and Jedi in training,Luke Skywalker attempted to infiltrate the palace via the sewer system, the dianoga was killed by smuggler Dash Rendar after he was trapped in its chamber.
Behind the scenesEdit
The giant dianoga made its first and only appearance in the video game adaptation of Shadows of the Empire as the boss of the "Sewers of Imperial City" level. Since the game's storyline directly contradicted that of its source material, Dash's encounter with the beast may or may not be considered canon. However, that doesn't necessarily discount the canonical status of the species itself.
