The critically endangered Sister Islands rock iguana is showing signs of recovery on Little Cayman, but a growing genetic threat could undermine years of work to save one of Cayman’s rarest native animals.

They are protected by law and remain among the islands’ most important endemic species. For a more complete summary of the story, please see the below link:
