Why do plankton migrate vertically?
Zooplankton may also migrate vertically within water columns to avoid the harmful UV light that penetrates the surface waters in daylight hours (Manuel and O’Dor 1997).

Why does vertical migration occur?
The migration occurs when organisms move up to the uppermost layer of the sea at night and return to the bottom of the daylight zone of the oceans or to the dense, bottom layer of lakes during the day.
