It has a muddy seabed, with scattered abyssal hills that covers an area approximately half the size of Europe's landmass. Its depth ranges from to . Characteristics The Porcupine Abyssal Plain is a vast, relatively level stretch of seabed with a depth range of . It has a muddy floor in the abyssopelagic zone and scattered rocky abyssal hills that rise into the bathypelagic zone forming seamounts and knolls. The water at this depth is relatively stable and moving slowly towards the south and southeast. There is a downward flow of organic detritus derived from primary production in the upper layers of ocean that settles on the sea floor. Fauna A large number of marine invertebrates inhabit the abyssal plain. About 90% by number and biomass of the macrobenthos are sea cucumbers and s ...
