Benthos
Benthos explained in an easy to understand way:


Have you ever tried finding your misplaced keys hidden among all the clutter on your desk? Just like your keys, benthos are organisms that can be hard to spot as they live on or near the ocean floor, often camouflaged among rocks, sand, and seaweed. Just as you sift through papers and pens to find your keys, scientists explore the ocean floor to discover these hidden organisms, both requiring patience and attention to detail to uncover what lies beneath the surface.
