Native to the seas of Naboo, and averaging 40 meters in length. the colo claw fish's body is dorsoventrally flattened like a slug, with a fringe of bioluminescent nodules around the perimeter. A large, crocodilian snout carries numerous sharp teeth, and the jaw is capable of unhinging. Two eyes protrude on eyestalks. Long, hooked, insectoid forelegs project from behind the head. Bioluminescent dorsal spines run the length of the fish. Overall, the colo claw fish can weigh in excess of 2 tons. Colouration ranges from green to yellow.
Colo claw fish have a venomous bite, and can generate a strong sonic burst with a screech, using it to stun prey.
In the wild
Colo claw fish are found in the depths of Naboo's seas, where they hide in underwater tunnels carved in the rock by plasmatic magma, where they can sit motionless for hours until suitable prey passes by. When prey draws near, the fish attacks from ambush from its tunnel. Colo claw fish have been known to use their bioluminescence to attract prey. These fish are indiscriminate feeders, swallowing anything they can fit down their throats, often alive, their forelegs aiding in gripping and controlling their catch. Their stomachs are capable of expanding, leaving some well-fed fish looking bloated. Sometimes, immature opee sea killers are swallowed alive, which often chew their way out the colo claw fish from the inside.
In Episode I
Traversing Naboo's seas in a bongo submersible, Qui-Gon Jinn, Obi-Wan Kenobi, and Jar Jar Binks were attacked by a colo claw fish, only to be saved when it is eaten by a sando aqua monster.
