The Lesser Caymans Iguana or Cayman Brac Iguana or Cayman Island Brown Iguana or Sister Isles Iguana (Cyclura nubila caymanensis) is a critically endangered subspecies of the Cuban Iguana (Cyclura nubila). It is native to two islands to the south of Cuba: Cayman Brac and Little Cayman, which are also known as the Sister Isles due to their similar shapes and close proximity to each other. This subspecies is in decline due to habitat encroachment by human development and predation by feral dogs and cats. It is nearly extinct on Cayman Brac (less than 50 animals) and Little Cayman supports a population of 1,500 animals.
