Diagram of locomotor modes used by (A) marine turtles and (B) freshwater turtles. Limbs of the same color move in-phase, while those of opposite colors move in anti-phase (sensu Long et al., 2006). ‘Dorsoventral’ and ‘anteroposterior’ describe the primary direction of motion for the limbs. During synchronous dorsoventral flapping [as collected in Dougherty et al. (Dougherty et al., 2010)], limbs marked ‘X’ lack propulsive function. Arrows point anteriorly.
