... ). If surface swimming during long travels is for navigation purposes (e.g. using celestial cues) ( Bonfil et al., 2005 ), it would mean a trade-off between navigation and energy saving, a topic that would merit further investigations. In conclusion, by using modern biologging technologies, we provided...
