A new study has revealed that aquatic crocodiles have undergone multiple evolutionary trajectories over time, which have resulted in a variety of adaptations to the aquatic environment. The research, published in the journal Nature, suggests that multiple lineages of aquatic crocodiles have been present since the Early Cretaceous, which is approximately 145 million years ago. The study also indicates that the various aquatic crocodile species have independently evolved several adaptations to the aquatic environment, such as paddle-like forelimbs, webbed feet, and a streamlined body shape. This suggests that aquatic crocodiles have been able to successfully adapt to different aquatic habitats over time.
