neritic

The plancton is the life that floats in loose clusters or forming cloud-like groups across the neritic surface, even descending to the abyssal depths.

In the highest, is the so-called neritic zone,—the oceanic surface, diaphanous and luminous, far from any coast.

The corpses of the neritic animals and of those that swim between the two waters are the direct or indirect sustenance of the abyssal fauna.

Living in the abysses where the light never penetrates, the pelagic animals are not obliged to be transparent or blue like the neritic beings on the surface.
