For a hundred fathoms the sun rays penetrate
The sea is warm and full of life
Phytoplankton turn the sun’s energy into food.
The sunlight zone is what we know
Where the dolphins play
It’s the ocean blue.
Varying by season and latitude
Fish and seagulls, squids and jellyfish
Tiny copepods feed giant whales.
Below is the twilight zone
Worthy of Rod Serling
It’s dimly lit and cold, but still supports life.
Fish eyes are large, directed upwards
Then there is the deep, the midnight zone
Constant darkness, except what creatures themselves provide
Crushing, almost freezing.
Thousands of feet down
The water’s weight presses down
Yet the sperm whale can dive here.
He searches for food
At depths we can’t imagine
He recycles and moves nutrients.
His carcass stores carbon
Providing habitat and food for others
He’s an ecosystem engineer.
He lights up our life
When he leaves the page
We discover the real darkness and cold.
