For much of their evolutionary history, whales have been divided into two main lineages: baleen whales and toothed whales. The toothed variety are especially diverse today, including sperm whales, belugas, porpoises, and so, so many dolphins (among others). This episode, we explore what makes toothed whales distinct – besides the obvious – and what the whale fossil record tells us about how they came to be among the most successful marine animals in Earth history.
In the news: leaf-eating birds, tiny whales, whale-like reptiles, and giant whales.
