Devilsquid were a species of cephalopod that dwelt within the deepest regions of the oceans of the planet Dac, such as Devil's Crevasse. They were far larger than an adult Human and known for being aggressive predators. They were highly similar in both name and appearance to demonsquid of Aquaris.
In 137 ABY, Master Treis Sinde of the Imperial Knights used the Force to command a large number of Devilsquid to attack a Sea Leviathan, a creature created by the Givin scientist Vul Isen of the One Sith to bring about the extermination of the Mon Calamari. The squid overpowered the monster, and pulled the beast into their lair where they subsequently devoured it.
