have been described so far in Pomacentrids. Nevertheless, it is often
unknown which sound component (particle motion or sound
pressure) is more relevant to most of the species for detecting
sound at the hearing threshold (Horodysky et al., 2008). For example,
hearing in Stegastes (syn. Eupomacentrus) dorsopunicans (Pomacentridae)
resulted to be governed by particle motion around 100 Hz, but
it was dominated by pressure detection at frequencies of 300 Hz
