They are sometimes referred to as ocean layers or environmental zones. The ocean environment is divided into two broad categories, known as realms: the benthic realm (consisting of the seafloor) and the pelagic realm (consisting of the ocean waters).elow this layer, down to the deepest parts of the ocean, it is perpetual night. This last layer is called the aphotic zone (meaning without light). At one time, scientists thought that very little life existed within the aphotic zone.
