Exploring the Deep Sea Food Web

The deep sea appears barren, lifeless, and silent. The lonely expanse rolls out into a long horizon, while the great abyss plummets ever-downwards into darkness.

Communities of life are solitary. They seem isolated from other habitats in the deep. But there is more going on here. The exact nature of the deep sea food web is still not fully understood, but advancements in technology and research in recent years have granted us a greater understanding of how these separate settlements of life are interconnected as one. Let’s take a closer look at the food web of the deep sea.
