Of the mammals, 1 is dual form due to the nature of its natural home, by the name of Demanit, Yofores Range, where it has adapted in it's (observed as) secondary form an almost unique ability to 'root' itself to the ground when it encounters gravity eddies. This form also compensates for instances in which the animal is shot into the atmosphere or beyond, it can survive for days until it 'swims' to a path which will bring it back down (the form also quite impressively avoids any atmospheric entry damage or any hard collision damage).
