Figure 1: The close resemblance between the teeth of Janjucetus hunderi (a-d) and those of the currently living crab-eating seal, Lobodon carcinophagus (bottom image). (Seal image courtesy of Dr. Alistair Evans, Monash University, Australia.) QUESTION: 1. Refer on the image showing the teeth of the fossil whale Janjucetus hunderi. As you can see, the teeth are very complex and closely resemble the teeth of a seal living in Antarctica today. This seal, Lobodon carcinophagus, is called a crab-eating seal, but it's main diet is consists of krill, which it filters out of the water through its complexly cusped teeth. Krill are also major component of the diet of modern mysticeti. Why do the authors discount this similarity in tooth structure as evidence that Janjucetus hunderi was a filter feeder?
