Oscillograms (a, b) with corresponding power spectra in Myripristis vittata and M. adusta (c, d), respectively. This comparison enables to highlight the difference between sounds without pattern that consist of a continuous series of pulses forming a single block (illustrated sound of M. vittata is composed of 7 pulses grouped in one block) and sounds with pattern consisting of a discontinuous series of pulses forming several blocks (illustrated sound of M. adusta is composed of three blocks made of two pulses each). P pulses; B blocks; F harmonics; F0 fundamental frequency; Fpeak dominant frequency.
