Key biodiversity
Green sea turtles nest on Cocos extensively, and it retains a reasonably robust coconut crab population, as well as several rare terrestrial lizards no longer found on Guam.

Virtually all the seabirds nesting around Guam are on Cocos Island.  This comprises Common White Terns, Brown Noddies and Black Noddies.  The numbers involved are only small, by global standards.
