Did you know that a sound wave can travel through water at a speed of 5,400 kilometres per hour? In the 1990s, a team of scientists sent sound waves into the waters of the southern Indian Ocean to determine how far they could travel… and managed to pick them up off the coast of Washington state! The sound had travelled the entire width of the Pacific. Rather impressive, isn\u2019t it?<\/p>\n
Undeniably, the animal that best embodies the power of underwater sound is the blue whale. In favourable oceanographic conditions, its song can be heard by other whales up to 1,600\u00a0km away! As for the fin whale, its call can travel up to 250\u00a0km at the surface and 6,000\u00a0km in deeper waters. The call of the humpback can travel up to 6,400\u00a0km. In their dark and hostile environments, whales have developed exceptional hearing and boast some of the most varied vocal repertoires on the planet: pulses, moans, sounds, ultrasound… you name it!<\/p>","protected":false},"excerpt":{"rendered":"
