Table 1 Mean, standard deviation SD, minimum and maximum values for parameters of double-pulse calls in captivity for M. furnieri, C. guatucupa, U. canosai, M. atricauda, and in the wild for P. courbina. NI = no information. IPI stands for interpulse interval. n indicates the number of individual fish recorded.
From: Characterizing dual-pulse calls in five Sciaenid species
