If I'm not wrong:

Williams, T.M. 1999. The evolution of cost-efficient swimming in
marine mammals: Limits to energetic optimization. Phil. Trans. R. Soc.
Lond. B 354, 193-201.

(Well actually she says that specialists in different locomotion mode
expend more or less the same amount of energy by a given traveled
distance - at least between mammals - okay, we are not whale shark...)
