mesozooplankton

Mesozooplankton are tiny marine animals that drift in ocean waters, typically ranging from 0.2 to 20 millimeters in size. They include organisms such as small shrimp, copepods, and larval stages of fish and other sea creatures. These animals play a crucial role in the ocean ecosystem by serving as a link between phytoplankton (tiny plants) and larger predators, such as fish and whales. Mesozooplankton are essential for the marine food web and help regulate nutrient cycling in the ocean, making them important for overall ocean health and productivity.
