This life-size model of the De Vos Baleen Whale is based on the skeleton displayed below it. Nehalaennia was a baleen whale that fed on small creatures filtered from the water, much like the blue whale still does today. Very different from modern dolphins – like Flipper – that catch and eat fish with their teeth. The De Vos Baleen Whale was capable of swimming relatively fast, as indicated by its streamlined body shape. Nehalaennia lived in a moderately cold, shallow sea rich in food. It’s no surprise that many other dolphins, sperm whales, leatherback turtles, and fish swam in the area and that these animals were already quite large for their time.
