Fig. 5. Axes of kinematic variation in prey capture as revealed by PCA. Each point
represents a feeding sequence on the respective axes for the species examined.
Note the separation of morays from A. rostrata on PC1. Magnitude of
angular excursions and all timing variables load positively on PC1 for morays
and negatively for Anguilla rostrata. Head loaded strongly and
negatively on PC2. Moray eels, Muraena retifera and Echidna
nebulosa, exhibited more variable kinematics than the suction-feeding
Anguilla rostrata.
