Young Squeaker Catfish Can Already Talk and Listen to Their Conspecifics

摘要: Numerous fish species are able to produce sounds and communicate acoustically. Nevertheless, hearing sound production in fishes is poorly understood the ontogenetic development of acoustic communication has only been studied a few species. So far yellow marbled squeaker catfish Synodontis schoutedeni that shown be acoustically across generations at all postlarval stages development. In two further smallest size groups were not yet detect equal conspecifics. Increasing body S. correlates with increasing sensitivity for lower frequencies, decreasing higher pressure level duration stridulation sounds, decreases dominant frequency. The excellent sensitivities schoutedeni, which characteristic Otophysi (fish Weberian apparatus), probably reason their ability early
