Fig. 5. Typical ant feeding event in P. platyrhinos. (A) P. platyrhinos capturing ant prey. Time (s) is given in the lower right of each frame. As in all iguanian feeding events, prey capture occurs using the tongue. Upon tongue retraction, the rotation of the dorsal papillae is visible as the prey is transported into the mouth. Note the characteristic shape of the tongue, which is very similar to P. vitticeps and U. notata but unlike M. horridus. (B) Selected kinematic profiles. The gape distance profile is typical of iguanians showing the slow open phase before prey contact. Colored dots denote onset of mouth opening (red), prey contact with the tongue (yellow) and maximum gape (blue). Onset of slow open (SO), fast open (FO) and fast close phases (FC) are denoted by dotted lines.
