Figure 160.—On the beach the two species of Kogia can be readily distinguished. The pygmy sperm whale, K. breviceps, ([top]) reaches a length of about 11 feet (3.4 m); its dorsal fin is a small nubbin located in the latter half of the back. The dwarf sperm whale, K. simus, ([bottom]) reaches only about 9 feet (2.7 m); its dorsal fin, much taller and more "dolphinlike" in appearance, is located near the middle of the back. Coloration of fresh specimens is probably similar for both species—the lightened areas in the lower photograph are the result of decomposition. (Photos from Jekyll Island, Ga.
