copepod
Minute aquatic crustacean
Copepods are tiny crustaceans found in nearly every aquatic habitat, from ocean depths to freshwater ponds.
Most are less than a millimeter long.
They form a crucial link in marine food chains, converting phytoplankton into food for fish, whales, and other animals.
The water sample teemed with copepods.
