Communication and Perception
Pappogeomys bulleri perceives its environment primarily through sound, touch, and smell. Gophers have vibrissae around their face and wrists which aid in navigating in burrows. The ears of P. bulleri are unique when compared with other rodents. The bullae are comprised of very thick bone and show modifications in the stapes. These features are in response to their subterranean lifestyle. They do not have sensitive hearing systems for low or high frequencies, which may protect their ears from incessant underground background noises.
Pappogeomys bulleri communicates with conspecifics vocally. When confronted with each other, two P. bulleri will hiss or click their teeth at each other. In captivity they are known to squeal when angry or in pain.
