..., which was proportional to m b 0.05 ( Watanabe et al., 2011 ). Therefore, it can be considered that aquatic mammals, birds and reptiles adopt optimal swim speeds commensurate with their own resting metabolic rate and morphology, even among different taxa. The stroke frequency of sea turtles...

... the ADL, f H reached extremely low values: f H during the last 5 mins of an 18 min dive was 6 beats min –1 . Dive f H and minimum instantaneous f H during dives declined significantly with increasing dive duration. Dive f H was independent of swim stroke frequency. This suggests that progressive...
