Blue Iguana

The Blue Iguana, Cyclura lewisi, is a critically endangered species of lizard that is found on the island of Grand Cayman. It is estimated that only 25 of these animals still survive. It is expected that the population will be extinct within the first decade of the twenty-first century. The demise of this animal is due largely in fact to the introduction of human pets and indirectly by the destruction of their natural habitat.

Blue Iguanas occupy rock hole and tree cavity retreats, and as adults are primarily terrestrial. Younger iguanas tend to be more arboreal. The young are preyed upon by snakes, but the adult has no natural predators. The Blue Iguana sexually matures at three years old. While longevity in the wild is unknown, in captivity one individual lived to 67 years of age.

The Blue Iguana is primarily herbivorous, consuming leaves, flowers and fruits from over 100 different plant species. They very rarely eat insect larvae, crabs, slugs, dead birds and fungi. Mating occurs in May, and eggs are usually laid in June or July, in nests excavated in pockets of earth exposed to the sun. Individuals are aggressively territorial from the age of about 3 months.
