An abyssal plain is generally a flat seafloor at a depth of 3000-6000 m. Typically sediments cover them brought from the land to smooth out the surface.
Approximately 40% of the oceans floor is covered in abyssal plain.
They are found throughout all oceans, though rarely in the pacific and arctic.
Relatively barren environment, but fish, worms, and clam-like creatures have been found.
Can go over 1000 ft in distance and only gain 1 ft of elevation.
The average temperature of the plains are 0° - 4° C.
