Plankton Migration and Behavior

The video explains the largest daily migration on Earth, which occurs in the ocean. It describes how oceanographic research vessels use sound to track particles, revealing the vertical migration of plankton. These organisms move to the surface at night to feed and descend during the day to avoid predators. This migration is a global phenomenon occurring in every ocean.
