What anatomical feature distinguishes Waimanu from modern penguins regarding their mouth?
Answer
The presence of teeth
Unlike modern penguins that swallow fish and krill whole using specialized smooth bills and tongues, Waimanu possessed teeth. These teeth likely served to grasp slippery prey, indicating a feeding strategy that differed significantly from the suction-feeding mechanisms observed in contemporary penguin species.
