Figure 9

External similarities among the three extant river dolphins and Pontoporia. The painting shows shared characteristics including long and narrow rostrum, small eyes, and broad forelimb flippers. A poorly-developed dorsal fin characterizes Inia (top), Platanista (second from top), and Lipotes (second from bottom) but is absent in the coastal Pontoporia (bottom). Note that the painting is for comparative purposes only; the geographic ranges of these species are disjunct.
