The Incredible
Dolphin

Many people say dolphins are very intelligent. they seem to

be able to think, understand, and learn things quickly. But are

they smart like humans or more like cats or dogs? Dolphins

use their brains differently from people. But scientists say

dolphin intelligence and human intelligence are alike in

some ways. How?

FACT 1: Talk to Me

like humans, every dolphin has its own “name.” the name

is a special whistle. each dolphin chooses a specific whistle

for itself, usually by its first birthday. actually, scientists think

dolphins, like people, “talk” to each other about a lot of

things, such as their age, their feelings, or finding food.

and, like humans, dolphins use a system of sounds and

body language to communicate. But understanding their

conversations is not easy for humans. no one “speaks

dolphin” yet, but some scientists are trying to learn.

FACT 2: Let’s Play

Dolphins are also social animals. they live in groups called

pods, and they often join others from different pods to play

games and have fun—just like people. in fact, playing together

is something only intelligent animals do.

FACT 3: Fishermen’s Helpers

Dolphins and humans are similar in another way: both make

plans to get something they want. in the seas of southern

Brazil, for example, dolphins use an interesting strategy to

get food. When fish are near a boat, dolphins signal 1 to the

fishermen to put their nets in the water. Using this method,

the men can catch a lot of fish. What is the advantage for

the dolphins? Why do they assist the men? the dolphins get

to eat some of the fish.
