  Abstract: The objective of this research project was to study sound production by Scyllaridae, slipper lobsters, specifically the Spanish Lobster Scyllarides aequinoctialis (Lund) when swimming at or near the surface. This is the first published record of swimming sounds produced by slipper lobsters. Analysis of recordings of swimming sounds produced by S. aequinoctialis in the laboratory indicates a peak of energy in the range of 100 Hz to 6 kHz with higher harmonics. The swimming sounds are co-incidental noise produced by slipper lobsters swimming near the surface. Such sounds may have significance for these animals. \n Spiny lobsters and clawed lobsters produce sounds of a wide range of frequencies and amplitudes. Some of these sounds function as a means of communication with conspecifics. Others produce sounds to ward predators. Incidental sounds produced by feeding, walking or other biological processes may still be significant. Sensory organs that could detect particle motion at short ranges, millimeters to meters, are found on many decapod crustaceans. Regardless of whether the sound production is intentional or coincidental it may be detected by other animals and have biological significance. Several studies, for example, have shown that the relatively random noise associated with coral reefs; serve as homing cues for the larvae of reef dwelling animals
