Response of embryonic coral reef fishes (Pomacentridae: Amphiprion spp.) to noise [PDF]
, 2016 We investigated the ability of embryonic clownfishes Amphiprion ephippium and A. rubrocinctus to detect sound during incubation in benthic nests. The heart rates of embryos within eggs were monitored as the young fish were exposed to sounds in the range ...
