Acoustic/vibration behaviors in crustaceans

Crustaceans often have highly diversified and specialized acoustic apparatus. Over the centuries, the sound production and detection capabilities of this group have been brought to the attention of investigators and intensively described in the literature. However, the role of acoustic signals had remained largely unknown until early 21st century and only over the last couple of decades, it is being understood. Mechanisms of neuroendocrinal control that underlie acoustic behaviors have remained unknown until the present day. In this chapter, we aim to provide information on the ecological and behavioral backgrounds of endocrinological regulation of acoustic behavior in crustaceans, useful for future studies related to this field. First, we introduce the mechanisms of production/detection of acoustic and vibration signals and their function in crustaceans inhabiting different habitats from land to sea. We argue what makes differences or variables in the acoustic methods and transfer of information among different species, habitats, or contexts. Finally, we introduce recent studies highlighting anthropogenic noises as environmental pollutants capable of causing detrimental effects on crustacean habitats and communication.
