Baleen whale
Baleen whales are cetaceans classified under the parvorder Mysticeti. They are a widely distributed and diverse parv order of carnivorous marine mammals. Baleen whales use their baleen plates to filter out food from the water by either lunge-feeding or skim-feeding. Balaenids are distinguished by their enlarged head and thick blubber, while rorquals and gray whales generally have a flat head.
