Blue Iguana Photos Showing This Critically Endangered Lizard Endemic to Grand Cayman Island

The Blue Iguana, also known as the Grand Cayman Iguana, Cyclura lewisi, is a large blue-gray lizard endemic to Grand Cayman Island. Research and DNA analysis in 2004 determined this lizard to be a distinct species of iguana and not merely a subspecies of the Cuban Iguana, Cyclura nubila, as was previously thought. In addition to its distinctive blue-gray color, it has orange eyes, and spines on its back running from its neck to its tail. It is one of the rarest lizards on earth, and is considered Critically Endangered.

Blue iguanas have a body length of 20-30 inches. Including the tail, males reach a total length of five feet, and a weight of 30 pounds. Females are about 30% smaller. The species is mainly terrestrial, but young lizards sometimes seek refuge in trees, which they can climb without difficulty. They are primarily herbivorous, and eat fruit, flowers, mushrooms and leaves, and opportunistically, insect larvae, crabs, slugs, and carrion. They possess a nasal gland that permits them to excrete excess salt and potassium. They are believed capable of surviving for decades in their natural environment, barring predation, and one individual captive blue iguana in Brownsville, Texas, named Godzilla, survived to an estimated 69 years in captivity.

During the mating season, the blue coloring of this species is readily apparent, as males become a brighter blue. They perform a bobbing head movement as a kind of mating signal. After copulation, female blue iguanas lay from one to 22 large eggs in June or July in burrows they dig from ground exposed to the sun. Temperature in the nest remains a constant 32 degress C (90 degrees F). The mother disguises the nest by scattering leaves and debris over it. After incubation, hatchlings emerge from the soil one by one and scatter into nearby vegetation, where they are often preyed upon by snakes, rats, and other predators.

The primary threat to the blue iguana has been habitat loss, as fruit farms on Grand Cayman have been converted to grassland for livestock. Increased development has also reduced habitat, and has brought with it cats, dogs and rats, which are known to prey on lizard eggs and hatchlings, and sometimes adults. Traffic causes road kills, and some iguanas are captured for the pet trade. Other species of iguana have been introduced to Grand Cayman, which may bring about competition for resources and possible hybridization. The presence of several species of iguana also reduces understanding among the people of the importance in preserving the endemic blue iguana.

Since blue iguanas have become a tourist attraction in Grand Cayman, there is hope for survival of the species, but mainly due to captive breeding programs. The number of unmanaged blue iguanas in the wild is estimated to be fewer than 25 individuals, possibly as low as five. Recovery programs on Grand Cayman aim to build a managed population of up to 1,000 blue iguanas born in captivity and released into protected reserves. There are also off-island projects in US zoos aimed at preserving the species should disaster or disease strike the remaining blue iguanas on Grand Cayman. They are listed as Critically Endangered by the IUCN Red List.
