WONDERFUL CREATURES

The difficulties that the salmon has to overcome are not
limited to these. Recall that it hatched from the egg in a

branch of a river, in an internal part of the land. In order to
reach that point, it has to go the correct way when the

river forks into branches. Salmon do not make any mista-
ke in these choices and they always follow the correct

stream.

Now suppose that you were born and had grown up in a
house in a city. Then one day you left your house, travelled

for days and came to a place 1,500 km (930 miles) away from

home. Years passed and you desired to return to your place of
birth. Do you think that you could possibly remember streets
that you passed only once? While no human being could, salmon

can, and they always find their way completely accurately.

There have been various studies intended to establish how sal-

mon make this exceptional
journey. And it has been con-

cluded that salmon find their
way by use of “smell”.
