do humpback whales eat plankton?
Humpbacks have a small dorsal fin toward the flukes. Humpback whales (like all baleen whales) are seasonal feeders and carnivores that filter feed tiny crustaceans (krill - mainly Euphausia superba, copepods, etc.), plankton, and small fish (including herring, mackerel, capelin, and sandeel) from the water.
