How Otters Are Saving Earth’s Underwater Forests

In the southern part of Mexico City lies Xochimilco, a maze of canals filled with boats, music, food and tourists. It’s also one of the last remnants of the interconnected lakes that once surrounded Tenochtitlan, the ancient capital of the Aztecs. And within these canals lies the last remaining wild habitat of a strange, smiling salamander called the axolotl.

The Outer Banks, known as the "Graveyard of the Atlantic," is home to thousands of shipwrecks, including Blackbeard’s infamous Queen Anne’s Revenge. But beyond the maritime history, this fragile coastline is rapidly changing—threatened by shifting sands, rising seas, and intensifying storms that could reshape it forever.

Florida’s native crocodiles have found an unexpected sanctuary in the cooling canals at Turkey Point Nuclear Power Plant. This fortunate happenstance, along with tireless conservation efforts, are helping these once endangered predators make a remarkable comeback.
