This is the largest surviving Magnopsid. Living secluded lives in the thickly forested Peaks of Oroland, these animals subsist on smaller organisms living in leaf litter, or inside trees. These are always captured with a rapid, scissoring snap of their machete-like jaws. Moon dogs also visit forest streams, snapping up the various kinds of Arthrognathan river snakes and bugsalmon that dwell there. On certain nights they might even trace these rivers down into the Orolandic plains, fishing at dark with the night sky reflecting from their enormous, haunting eyes.
These animals are very rare; their population numbers at most at several tens of thousands. Further research is necessary to understand their cryptic lifestyle, and determine if their numbers are increasing or decreasing. It will be a truly saddening loss if these mystifying animals join the long list of spectacular but extinct Magnopsids.
