- adj. lacking light; especially not reached by sunlight
Sunlight rarely penetrates below 250 meters and this dark water without any light is called the aphotic zone.
Kirk stood in silence for a long time, gazing at the aphotic depths of interstellar space.
Straining her eyes into the aphotic depths beyond the carved and painted pillars -- no two alike and all gaily colored like psychedelic barber poles -- she heard the whispery hiss of the torch as it burned in her hands and the faint, quick creaking of Antryg's belt as he moved here and there, drawing out a five-point star within the double circle around them.
Something swooped at her, some winged and flabby thing whirling out of the aphotic pits of this non-being; she felt it cut her arm, felt blood hot on the cold flesh.
In particular, light measurements are performed at sunset because increased prey and predator interactions occur at twilight, when animals previously hidden in the deep, aphotic (without light) zone migrate vertically up to the surface.
In general, the deep sea is considered to start at the aphotic zone, the point where sunlight loses its power of transference through the water.
