Vertical migrations of a deep-sea fish and its prey.

It has been speculated that some deep-sea fishes can display large vertical migrations and likely doing so to explore the full suite of benthopelagic food resources, especially the pelagic organisms of the deep scattering layer (DSL).This would help explain the success of fishes residing at seamounts and the increased biodiversity found in these fe
