Aphotic zone

The aphotic zone (from the Greek ἂ ( ν ) -. A (n), un-, and φῶς Phos gene φωτός photos " light " ) is the zone of the ocean, entering the result of scattering, refraction and absorption no more light. Therefore, here is no photosynthesis and therefore no longer possible, such as in the euphotic zone of plant growth, and the animals living here can not see how in the dysphotischen zone. In the open ocean, this depth range is the largest.
