Most crocodilians today can handle saltwater to some degree, but many of their ancient cousins were much more suited to a life at sea, including some of the most impressive ocean-going reptiles in history. In this episode, we’ll explore the many lineages of marine crocs that have evolved over the last 150 million years, and we’ll dive into the special adaptations that allowed them to take to the seas over and over again.
