2. Living Fossils
Crocodiles and alligators are often called living fossils because they closely resemble their ancestors who walked the Earth millions of years ago. The fossil record shows that these crocodile-like reptiles have existed for over 200 million years, surviving mass extinction events that wiped out many other species. Their longevity is a testament to their adaptability and the effectiveness of their body design. Despite their ancient lineage, crocodiles and alligators are not relics of the past. They are thriving in their current ecosystems, playing a vital role in maintaining the health of wetlands and waterways.
