Fig. 2. Lateral view of larval (A) and adult (B) Eurycea bislineata. Tail aspect ratio (AR) is defined as the ratio of the square of maximum tail height (H) to lateral surface area (LSA) of the tail (shaded); AR=H2/LSA. (C) Aspect ratio versus total length. Aspect ratio differs significantly (P=0.0007) between larvae ({circ}) and adults ({blacksquare}) but is not significantly correlated with total length (P=0.4593; one-factor ANCOVA). Scale bar, 1 cm.
