-
A
dolphin looks more like a fish than certain fish do.
-
It has a smooth, streamlined body.
-
It
is an excellentswimmer.
-
As
its powerful tail moves up and down, the dolphin seems to flash through
the water.
-
Like
fish, dolphins are completely at home in the water.
-
There
they play, feed, sleep, and bear their young.
-
Dolphins
can live only in the sea. Yet they are not fish.
-
If
you watch a dolphin, you will see something that shows it is not a fish.
-
A
dolphin must come to the surface to breathe. Fish can take oxygen out of
the water. Dolphins cannot.
-
Like
us, they breathe with lungs and must take their oxygen from the air. And
like us, they are mammals.
-
Mammals
are a large class of animals with backbones.
