This photo was taken aboard a federal research ship off Kona in Hawaii in 2006. Pictured are fish eggs, crab larvae, rectangular photosynthetic diatoms, carnivorous arrow snails, and a least nine species of copepods.

Award-winning National Geographic photographer David Liitschwager captured the photo, revealing the less-than-obvious threats in the ocean.

National Geographic said of the photo: ‘Under a magnifier, a splash of seawater teems with life.

‘The planktonic soup includes bug-like copepods; long, glassy arrowworms; coiled filaments of cyanobacteria; rectangular algae called diatoms; fish eggs; and a big-eyed larval crab the size of a rice grain.’
