Humpback whale (like all baleen whales) are seasonal feeders and carnivores that filter feed tiny crustaceans, plankton, and small fish (including herring, mackerel, capelin, and sandeel) from the water. They are gulpers (not skimmers), filter feeders that alternatively swim then gulp a mouthful of plankton or fish. Concentrated masses of prey are preferable for this method of feeding. An average-sized humpback whale will eat 4,400-5,500 pounds (2000-2500 kg) of plankton, krill and small schooling fish each day during the feeding season in cold waters (about 120 days). They eat twice a day.
