These fossorial rodents bang their head against the walls of their tunnels. This habits was initially interpreted as part of their tunnel setting up behavior, but it was at some point recognized that they deliver temporally patterned seismic alerts for very long-length interaction with neighboring mole rats.[sixty three]
