Atlas Obscura: An Explorer’s Guide to the World’s Living Wonders

Lindsey Galloway first explored the Christmas Island red crab migration for BBC Travel, and when Atlas Obscura announced a call for submissions for its Guide to Wildlife Wonders, she knew this extraordinary phenomenon deserved a place in the book. 

She refreshed her reporting with new research and a heartfelt interview with a park ranger who has lived on the island his entire life, capturing not only the ecological wonder but also the human connection to it. The result was a rich, transportive entry that combined vivid storytelling, expert insight, and original photography—offering readers an unforgettable look at one of the natural world’s most astonishing migrations.
