The cave-rex is similar to the Raptor, in that it too possesses bio-luminescent traits. The luring apparatus located on its snout may suggest a hunting behaviour similar to anglerfishes, who use similar organs to hunt in dark environments. These traits may be synonymous with other cave-dwelling creatures around the cave-rex itself. The cave-rex could potentially be a boss mob.
