Freeze (Ex): A galeb duhr can hold itself so still that it appears to be a boulder. An observer must succeed at a Spot check (DC 30) to notice that it is really alive.

Tremorsense (Ex): A galeb duhr can automatically sense the location of anything within 300 feet that is in contact with the ground.

Galeb duhrs are usually solitary creatures, though they occasionally live with a few of their own kind. When approached, a galeb duhr can easily make it itself noticed. When irritated into combat, however, it attacks with its slams.

Earth Subtype

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.
