Fig. 4 Representation of the two main components of the Phylo-PCA (a) and PCA (b) made with five kinematic variables (predator-prey distance, body-ram distance, protrusion distance, suction distance, and strike duration). White dots correspond to no-zooplanktivorous species with the cerato-mandibular (c-md) ligament (no-zoo), red dots correspond to zooplanktivorous species with the c-md ligament (zoo.1), and orange dots correspond to zooplanktivorous species without the c-md ligament (zoo.2). For the phylo-PCA, phylogenetic relationships are highlighted in blue. The standard ellipses areas are represented by gray, red, and orange ellipses for no-zoo, zoo.1, and zoo.2 species, respectively. The convex hull areas are illustrated by gray, red and orange polygons for no-zoo, zoo.1, and zoo.2 species, respectively
