![Traveling Without a Map
People would get lost very quickly if
they tried to swim underwater from place
to place. There are no signs or buildings to
point the way in the ocean. Surprisingly,
however, sea animals do not get lost.
Scientists think that sea animals use their senses
to find their way. Some fish use their strong sense of
smell. It helps them notice the familiar scents of rocks
and plants along the way. Others use their sense of touch.
They feel the movement of waves, tides, and currents.
These clues help them map their journey.
Scientists have another interesting idea. They
think that some sea animals have a sense that
people do not. Something in the bodies of these
animals may act like a compass. This sense
may point them in the right direction.
Tag a Fish
Scientists are trying to learn more
about migration. They have invented tools
such as tagging to study how sea animals move.
Researchers catch a sea animal, glue or strap
a small tag to it, and then return the animal to
the water. The tag gathers facts about the animal’s
journey and sends a report to satellites above
the Earth. The satellites send the report back to
computers on land. People use this information to
learn about the patterns of the animals.
Reports about migration are useful. People from
different countries are sharing what they learn
so that we can all work together to protect sea
animals. Dr. Barbara Block is one of these people.
She believes, “The first step in protecting their
[sea animals’] future on Earth is knowing
where they go.”](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
