The more we learn about dolphins (1 ). the more we realize
that they are better organized and their society (2) is more compiex
than people (3) previously imagined. They look after other dolphins
(4) when they are ill, care for pregnant mothers (5) and protect the
weakest in the community (6), as we do. Some scientists (7) have
suggested that dolphins (8) have a language (9) but it is much more
proUNITIle that they communicate with each other without needing
"words" (10). They have an echo-location system (11) which is
similar tg a bat's system (12) and much more sensitive than our
hearing (13), so the most important task (14) of a dolphin's brain
(15) is to transmit and receive sound (16).
