DARK DEPTHS Every night under the waves, a vast diversity of creatures from single-celled organisms to fish larvae and molluscs take part in the largest animal migration on the planet. Known collectively as zooplankton, they rise vertically to the surface to feed, accompanied by hungry predators. The daily movements of zooplankton help remove carbon from the atmosphere by transporting it down to the bottom of the sea. Some scientists believe the movement created by this vertical migration can have as much impact on ocean circulation as tides and winds.
This photograph is from a series by Magnus Lundgren, who captured the images at night by placing a ‘downline’ with light stations for 40 metres under the surface to attract plankton. Below him the sea stretched between 200 and 2,000 metres. Photograph © Magnus Lundgren / naturepl.com
