Biology and appearance
Dianoga were sentient cephalopods characterized by seven suckered tentacles, an eyestalk, a mouth of sharp teeth, and several hearts. They could grow to a length of 7 to 10 meters. Their blood had a blue tint.
The normal skin color of a mature individual was a deep purple, but dianoga could change their color and patterns for active camouflage. They could notably turn black, gray, and even transparent. They also had the ability to regenerate lost limbs.
Society and culture
Dianoga had a primitive tribal culture. When they were not feeding, they often spoke a deep, complex humming language. Because its reverberations carried so completely in the water, that language scared away all nearby prey. Their people venerated water, which they called "the Great Cleanser When It Was Time to Be Cleansed", and believed in reincarnation.
Dianoga in the galaxy
One dianoga inhabited the junkyard world Bracca during the early days of the Galactic Empire. The being made a home within the waters that flooded the remains of a derelict Venator-class Star Destroyer, one of many such vessels left for scrap on the planet. Around the year 19 BBY, members of the rogue clone commando squad Clone Force 99 entered the wrecked cruiser, searching for a medical bay within the ship. One of their number, the hulking Wrecker, briefly wrestled with the dianoga when he found himself dangling from a cable over the being's watery home. Blasterfire from the other clones, however, drove the dianoga off and ended the encounter.
At some point before the Battle of Yavin in 0 BBY, a female dianoga named Omi was captured by Vodrans, who handed her to members of the Empire en route to their new Death Star battle station. She was dumped into the Death Star's garbage masher 3263827, where she would feed on the organic materials that occasionally fell in. During the rescue of Leia Organa, Luke Skywalker first realized something was alive in the garbage compactor, but shortly after his realization, Omi dragged Skywalker underwater. Han Solo and Organa were unable to locate him, but the dianoga released him just before the walls began to close.
