Join the professor
for a tour into our watery realm
|
Imagine
trying to live in a stream instead of on land. It would be like living
in a constant hurricane. Not only would you have to fight for your life
to stay put or find shelter, you would also have to gather and eat food,
extract oxygen from water, and reproduce in the maelstrom.
Most
of the food items available to you are whizzing by you and being swept
down stream.
Then
consider the difference in the stream flow from one season to the next.
In March and July, the stream bed may be almost completely dry. In September
and October, it may be in full flood with rocks tumbling down stream.
It takes very special adaptations to live in this environment.
