Vocal–Acoustic Communication in Fishes: Neuroethology

摘要: In terms of species number, teleost fishes are the largest group living vertebrates. Current estimates show that majority all known orders teleosts include produce sound, many which have clear social communication functions. Fishes exhibit a diverse range musculoskeletal mechanisms may independently evolved for sound production. This includes rapid contraction paired vocal muscles vibrate either swimbladder or pectoral girdle, and rubbing together ( stridulation) parts girdle–fin complex, oral jaw, pharyngeal teeth. By comparison, tetrapods only two major types organs, syrinx birds larynx other nonavian groups. The more conserved tetrapod pattern depend, in part, on dependence their vocalizations respiration. Unlike peripheral mechanisms, functional organization those regions central nervous system (CNS) controlling among vertebrates is highly across distantly related groups terrestrial Hence, available data suggest both behaviors neural bases acoustic first retain basic organizational features recently tetrapods.
