Tadpole body shape data for 166 species. Landmarks and semilandmarks for characterizing the body shape of tadpoles. 1 Centre of the eye 2 Centre of the external nares 3 Point where the upper labium contacts the head/body 4 Point where the lower labium contacts the head/body 5 Intersection of the head/body and tail on the ventral side, anterior to the vent 6 Intersection of the ventral edge if the tail muscle and the head/body 7 Intersection of the dorsal edge if the tail muscle and the head/body 8 Tip of the tail 9 Point on the dorsal fin closest to landmark 7 (superficially denotes the intersection of the head/body and tail regions) 10 to 17 Equally-spaced semilandmarks marking the curve of the dorsal aspect of the head/body when viewed laterally 18 to 27 Equally-spaced semilandmarks marking the curve of the dorsal aspect of the tail fin when viewed laterally 28 to 37 Equally-spaced semilandmarks marking the curve of the ventral aspect of the tail fin when viewed laterally 38-45 Equally-spaced semilandmarks marking the curve of the ventral aspect of the head/body when viewed laterally 46 to 55 Equally-spaced semilandmarks marking the curve of the notochord
