The sounds of crashing waves and calling whales boom beneath the surface of the ocean, though they aren’t the only sounds that travel there. In fact, throughout the past couple hundred years, humans have added a cacophony of new noises to the sea soundscape, harming the many marine species that rely on sound to survive.
Dolphins comprise a major component of these sound-reliant species. And, according to a recent paper published in Current Biology, though these animals try to communicate with one another over their increasingly strident surroundings, their attempts at “shouting” aren't always the most successful.
