Can dolphins talk? Maybe they can’t

Can dolphins talk? Maybe they can’t talk with
words, but they talk with sounds. They show their
feelings with sounds.
Dolphins travel in a group. We call a group of fish a
“school.” They don’t study, but they travel together.
Dolphins are mammals, not fish, but they swim together
in a school.
Dolphins talk to the other dolphins in the school.
They give information. They tell when they are happy
or sad or afraid. They say “Welcome” when a dolphin
comes back to the school. They talk when they play.
They make a few sounds above water. They make
many more sounds under water. People cannot hear
these sounds because the sounds are very, very high.
Scientists make tapes of the sounds and study them.
Sometimes people catch dolphins for a large
aquarium. (An aquarium is a zoo for fish.) People can
watch the dolphins in a show. Dolphins don’t like to be
away from their school in an aquarium. They are sad
and lonely.
There are many stories about dolphins. They help
people. Sometimes they save somebody’s life. Dolphin
meat is good, but people don’t like to kill them. They
say that dolphins bring good luck. Many people
believe this.
