摘要

SYNOPSIS. As burrowing, nocturnal predators of small arthropods, sand scorpions have evolved exquisite sensitivity to vibrational information that comes to them through the substrate they live on, dry sand. Over distances of a few decimeters, sand conducts low velocity (similar to50 m/sec) surface (Rayleigh) waves of sufficient amplitude and bandwidth (200
