Humpback whale lunge feeding on Antarctic krill, with mouth open and baleen visible. The humbpack's throat grooves are seen as its pleated throat becomes fully distended as the whale fills its mouth with krill and water. The water will be pushed out, while the baleen strains and retains the small krill.
