Ocean sounds

Sound travels through water at about 4,869 feet (1,430 m) per second - five times faster than it travels through air. Many water-living animals use sounds for communication. The deep or low frequency calls of the great whales travel for hundreds of miles through the seas. Male humpback whales sing to attract females. Each individual has its own song and repeats it with small variations for hours on end. Mother great whales and their babies, or calves, also make clicks and squeals. (World of Science)
