All creatures great and smaller: a study in cetacean life history energetics
This paper reviews some specific studies of cetacean life history energetics over the past 20–30 y that include one of the largest species, the baleen fin whale, Balaenoptera physalus , the medium-sized odontocete long-finned pilot whale, Globicephala melas , and one of the smallest marine odontocet...
