Table 6. Summary of Grad-CAM results for each class (males)

P. bocagei

Highly variable (no clear pattern). All portions of the dorsal views were equally used. In head images the area around the eye, the top of the head, the snout and the throat were all used in similar proportions.
P. carbonelli	Variable for both views. Snout and middle of the dorsum used in dorsal view. Top of the head most frequently (but not strictly) used in lateral view.
P. guadarramae	Whole body used for dorsal view (but variable); either throat (most common) or ear region used in head lateral views.
P. hispanicus	Variable. Anterior portion of snout used more frequently than in other species for both dorsal and head lateral views.
P. liolepis	Highly variable. Whole body used in most dorsal images, area around the eye and throat used in head lateral views, but other patterns common.
P. lusitanicus	Highly variable. All parts of the dorsum used (but frequently the most posterior part); area around the ear frequently used in head lateral images.
P. tunesiacus	Highly variable. Dorsal area near the insertion of the posterior limbs used more frequently than in other species; different regions of the head used, often simultaneously.
P. Ʋaucheri	Highly variable. Different regions of dorsum (from head to the posterior region) used in dorsal images, all portions of the head, but most frequently the throat, used in lateral images.
P. Ʋirescens	Highly variable. All parts of both images used. Head and anterior part of the dorsum more used than in other species.
