|The sand scorpion uses two types of sensors on the tips of its legs to detect mechanical vibrations transmitted over relatively short distances across the surface. One sensor, called the basitarsal slit sensillum, detects surface waves, or ripples. The other type--consisting of numerous sensory hairs touching the surface--responds to compressional waves traveling through sand. Physicist J. Leo van Hemmen of the Technical University of Munich in Germany and his coworkers have developed a computational model of how a scorpion pinpoints its prey...|
