Dytallic Laser beast

An unusual crystiline lifeform found deep within the mines of the planet Dytallix B, in the Mira star system. The laser beast moves from cave to cave seeking out radioactive materials for nourishment. It also travels the tunnels and mineshafts created by humans, sometimes creating new passages itself. This unusual creature resembles a crystalline scorpion, or a Tholian, though unlike the latter it is flat. It possesses three pairs of legs and a curving tail ending in a thick bulb. Made entirely from crystal, the laser-beast shimmers in the light. It has no visible features but under close examination a faint spark of light can be seen dancing from facet to facet throughout the body, and is both brighter and more active in the stomach region.
