Unidentified Kankalo Belt Containment Zone creature

This unidentified crustacean species is a species of non-sapient spaceborne predators, one of which was held in the Kankalo Belt Containment Zone by the Galactic Empire due to how dangerous it was.

Biology
Members of this species are massive crab-like spaceborne creatures, covered in bumpy red armor. They bear four claws, one small set closer to their heads, and one large set. Members of this species are strong enough to tear apart Star Destroyers with their claws, and are presumably immune or highly resilient to turbolasers and other Imperial weaponry. They are also known to be carnivorous, and able to see or otherwise sense considerably smaller organics, such as Humans, inside of large spacecraft, with their only visible eyes being at the ends of two eyestalks. Their method of locomotion is scuttling and jumping across asteroids and other objects in space, and they become incredibly aggressive when disturbed.

History
At some point in time before 12 BBY, at least one member of this species was successfully contained in the Kankalo Belt Containment Zone, an asteroid belt in the Mid Rim of the galaxy. Due to the danger the creature posed, Imperials of all rank, including governors, were prohibited from entering the containment zone, and Imperial protocol was to not disturb the creature. Sometime between 12 BBY and 0 ABY, Darth Vader, a Human cyborg Sith lord, was placed under the command of Imperial governor Ahr, who took advantage of his new authority to torment the Sith lord in an attempt to kill him, such as having Vader face armies of Rebels and droids alone. After a few failed attempts, Ahr took Vader out to the Kankalo Belt Containment Zone, despite the crew's protests, ordering him to find the greatest threat to the Empire and destroy it, intending to have the creature kill Vader. Vader found the creature in his spaceship, getting its attention, but then turned around and returned to Ahr's Star Destroyer.

Ahr, angered that Vader was disobeying him, ordered him to go back outside and kill the creature, but Vader told him that his orders were to destroy the greatest threat to the Empire, which he deemed to be Ahr, who had jeopardized missions and soldiers in an attempt to flaunt his power, culminating in breaking Imperial regulations simply for pleasure. Unbeknownst to Ahr, Vader had lured the creature all the way back to the Star Destroyer, with Ahr too busy yelling at Vader to see it approaching. When Ahr ordered Vader to kneel, Vader saw the creature reaching towards the ship with its claws, and knelt for safety. Ahr began to laugh, just before the creature punched through the bridge and grabbed Ahr, killing him by dragging him into space. Vader casually left the ship as the creature tore the Star Destroyer apart, pulling crewmen out for food and returning to the depths of the containment zone.
