It lies between the mesopelagic above, and the abyssopelagic below.
Zone Characteristics Epipelagic sunlit zone: top layer of the ocean where sunlight penetrates Mesopelagic twilight zone: a dim zone where some light penetrates, but not enough for photosynthesis Bathypelagic midnight zone: the layer where no light penetrates Abyssal zone pitch-black bottom layer; the water here is almost freezing and its pressure is immense Hadal zone waters found in the ocean's deepest trenches Although we think of land when we hear the word biome, there are also aquatic ...
