纳米布金鼹鼠的昆虫猎物聚集在散布在纳米布沙漠沙丘中的草丛下。在通常吹过纳米布沙漠的微风的存在下，这些草丛发出低幅度的振动，通过沙子传播。当在沙子游泳模式下(在沙子表面下几厘米处)觅食时，一些鼹鼠显然被吸引到人造来源，发出与草丛记录的振动相匹配的振动。这是这些沙漠哺乳动物使用地震信号导航的第一个直接证据。
Insect prey of the Namib golden mole congregate beneath clumps of grass scattered among the sand dunes of the Namib Desert. In the presence of the light winds that typically blow over the Namib Desert, these grass clumps emit low-amplitude vibrations that are transmitted through the sand. While foraging in the sand-swimming mode (a few centimeters below the surface of the sand), some moles apparently were attracted toward manmade sources emitting vibrations matching those recorded from the grass clumps. This is the first direct evidence that these desert mammals use seismic cues for navigation.
