Exactly like other whales, dolphins live in a dark world except when
they surface.

Deeper down in darkness, eyesight is not important, and most
dolphins don't see very well.
Some, especially river
dolphins,
live in such murky waters that they are almost blind, barely able to
use their eyes to distinguish night from day. Like whales,
dolphins
have therefore made full use of the fact that sound travels very well
in the water, and developed an excellent sense of hearing.
Dolphins
don't sing long, low-frequency songs
like do baleen
whales,
but they use short squeaks and other noises in a communication almost
as complex as a language.
Some,
like belugas can be so noisy that they can be heard from out of the
water.
Dolphins have also got a good sense of touch and they also
communicate by touching each other.
The species that have good enough
eyesight, also communicate by leaping out of the water and putting on
some surface display.
