The Mysticeti, or baleen whales, have a filter-feeding system, are fifteen species in three families, and include the blue whale, right whales, bowhead whale, humpback whale rorqual, and gray whale. The wide range of body mass in cetaceans has a significant influence on the capacity for oxygen storage and use, which affects dive limits.

They are generally solitary or ...
