Electro Crawler

Electro Crawler's are large, 8 limbed creatures who can release large jolts of electricity through their body to electrocute anything it is touching. They are found only on the planet Lisag, and evolved from smaller creatures brought to the planet much earlier, probably on a Horin expedition.

Appearance
Electro Crawlers are 2-3 feet long, coming in either black, white or grey. They have 4 large red eyes which are readily visible even in the dark and 8 legs. Their body is covered in short hairs that bristle with electricity at random times.

Behaviour
Electro Crawlers are patient and cruel creatures. They can create long strings of an electrified substance they create in their abdomen and then attach the strings to either side of a tunnel, or simply lie the strings along the ground. Either way, once prey interacts with the strings they are immediately paralyzed by the electricity and the strings retract, catching the prey and holding it taught as the Crawler moves in to eat its prey. Crawlers have been known to capture prey and keep it tied up for days, weeks or months until it dies of starvation or of the electric shocks that the Crawler will release into the cocoon-like structure. After the prey dies, however, it is sometimes left and never actually eaten by the Crawlers. How this benefits the Crawlers is unknown. The Crawler's defense mechanism is to release an electric charge through their body when attacked.

Habitat
Electro Crawlers are found throughout the caves on Lisag, and are a serious problem for miners on the planet. They become more common as the caves grow deeper, and have blocked off several passage ways altogether.
