gravity is what makes bones dense, that constant pressure of gravity compacts the minerals - without that gravity, as in 0 G which is THE EXTREME of 'low gravity', bone density is lost at an alarming rate when astronauts don't exercise properly

these monsters (except congolala maybe, lazy butthole) are definitely active enough to support proper bone growth in a LOWER gravity environment, a no gravity environment? that'd be cool but not practical
