Sound is useful for dolphins to stay with their pack and hear fellow dolphins shout alarums, but sight is also important for finding the surface and escaping said danger.

sound
sound can be produced in any medium - air, water and solids too, but most of the sounds we hear are through air. Animals like dolphins produce sound in water and hear it there.
dolphins can hear very well. They have tiny holes either side of the head. The specialised anatomy of a dolphin ear helps it to localise sound underwater, so that they can work out exactly where the sound is coming from. Humans can't do this underwater. Most sound reception probably occurs however, through the fatty tissue in the lower jaw
