Write a detailed description of a dark scene outside a coastal area with sea stars, hissing bubbles, and plankton.
assistant
Visibility is extremely poor due to the gentle waves mixing clumps of hissing bubbles, fine sand, swaying algage and other debris into the water column. Softly glowing sea stars migrate slowly in search of food while equally luminescent plankton contribute to the churning haze. The terrain continues to decline, steeply descending into darker, deeper waters. A soft purple glow can be seen to the northeast.
