The little known cousin to mons montis is terrigena interior (born inside/from the earth) which looks similar to a miniature montis with enlarged adamantine hard protection plates and neck ridges. These creatures, however, have no wings, not even vestigal ones. They also are blind, relying on scent marking and special vibration sensors located primarily at the base of each of their "hairs" to move around. Terri is not prolific, each female lays usually only a single fertile egg at any mating, and never lives in groupings (not even as juveniles). Males are considerably smaller than the females, generally full grown males are only half the size of a juvenille female. They have a harder time in life as many die when attempting to mount a female that has recently mated, ending their life around the age of fifteen. Male terri also don't have set territories like the females, but they do try to stay out of each other's way as much as possible. Females in uncontested territory live to around eighty years old and are fully mature at three years but don't begin mating until they're around ten. Usually there is only one fertile egg laid (if there are more the female will relocate her territory to accomodate the male better and protect him, if possible, while he resides there) and the young is raised at the edge of the mother's territory. At about six months old when it first possibly can protect and feed itself it is forcibly removed from the nest. If it is male it runs the chance of meeting its absentee father and being killed outright as it will probably end up a rival on the father's usual route.
