Is a copepod a herbivore?
Copepods are the most important herbivores in the sea, filtering phytoplankton using a sophisticated ‘fling and clap’ technique to grasp the tiny plants while squeezing the water through fine meshes on the limbs. Some species are modified as carnivores and eat other copepods using limbs armed with sharp spines.
