Â*Â*Â*Â*Â*Yes Shrink, you are right.. in a way. Take a look at this picture I took while at Oddworld:
Glukkon sculpture
In this picture, you can clearly see the Glukkons have arms, but they are used for walking. The only thing they have underneath their suits are vestigial legs and feet. Whether or not these are used practically, I cannot say.
