The population of the birds must have been kept between 30 and 50 individuals by population limiting factors such as the presence of predators within the community or competition for resources such as food or spaces.

- The organisms like sharks and deep sea fish in this zone have to reach above them for breathing dissolved oxygen as this zone has no such plants to produce oxygen.
