Many vertebrates, including teleosts, rely on acoustic signals for communication (Myrberg and Lugli 2006). Sound production has been documented in four species of sand gobies (Pomatoschistus). Males of the sand (P. minutus), marbled (P. marmoratus), and canestrini (P. canestrinii) gobies produce low-frequency pulsed sounds when females enter the nest (Lugli and Torricelli 1999). The male painted goby (P. pictus) also produces similar drumming sounds outside the nest during courtship (Amorim and Neves 2007). These drumming sounds present interspecific differences, suggesting that they could potentially be used in species-specific recognition (see Table 1). |
