Marine biologyAnimal behavior
Quick Answer
Diel vertical migration is the daily movement of marine animals up and down the water column. Many creatures rise toward the surface at night and descend by day.
The Full Story
This behavior is one of the largest synchronized migrations on Earth. Zooplankton, lanternfish, and squid often move upward under cover of darkness to feed and avoid predators, then retreat to deeper water in daylight. The pattern reduces exposure to visual hunters and helps organisms balance feeding with safety. By moving carbon-rich material to deeper waters, these migrations also affect the global ocean carbon cycle.
