... of the tail slap and body pulse sounds in Chaeotodon species are correlated with body size and can provide honest communication signals. Future studies on fish acoustic communication should investigate low-frequency and infrasound acoustic fields to understand the integrated function of the ear and lateral...

... vicinity. Such signals could arise from ground-to-air coupling of near-continuous microseisms, or from scattering of direct microbaroms off terrain features, both of which are initially generated by wave–wave interactions in the deep ocean. HARPA runs show that little or no infrasound from the loft area...

...Hans E. Karlsen; Robert W. Piddington; Per S. Enger; Olav Sand SUMMARY Acoustic stimuli within the sonic range are effective triggers of C-type escape behaviours in fish. We have previously shown that fish have an acute sensitivity to infrasound also, with acceleration thresholds in the range of 10...
