How do marine animals navigate the oceans?
Marine mammals also use underwater vocalizations to communicate with each other. Because sound waves travel efficiently in water, some ocean-dwelling animals are able to communicate over great distances through sound. Based on the few marine mammal species for which hearing has been tested to date, it appears that a given species’ hearing is tuned to a broad range of frequencies with the greatest sensitivity typically encompassing the range of vocalizations and echolocation (for echolocating species).
