Glim worm

found on a variety of planets, the many species of glim worm resembled tube-like predators which were covered with sharp scales. They were highly adaptable, living in the desert as well as urban areas. They burrow quite well, and have developed a complex musculature that allowed them to flow across a wide range of surfaces. Glim worms hunted by detected the subtle vibrations caused by the movement of their prey, and had only to come in contact with they prey in order to catch it. Their muscles could then be used to extende their sharp scales, literally grabbing their prey. Just beneath the skin's surface, specialized glands secreted a gluey substance that further enhanced their hold on the prey, and further muscular manipulation literally rolled the prey into the glim worm's mouth. All the prey captured by a glim worm was eaten whole.
