Interestingly, the deep ocean (slope and abyssal regions) tends to have more species (both planktonic and benthic) than shelf and coastal habitats. For a wide variety of animal groups, diversity increases with increasing water depth reaching a maximum at around 2,000 m [13]; below this depth diversity decreases with increasing depth.
