Identifying Temporal Differences in Vibration Receptor Activation in the Sand Fiddler Crab, Uca Pugilator

Substrate vibration is used in numerous organisms as a means of communication. Herein we explore the role of substrate vibration in the process of localization in Uca Pugilator, the sand fiddler crab, by tracking temporal differences in receptor activation. Extracellular recordings of receptor activity were amplified and analyzed. Analogous systems are outlined and applied to our case, including relevant information from studies on scorpions. It seems the fiddler crab uses a spatial array of vibration-sensitive receptors to localize sound sources. Our behavioral studies, alon
