Cyclura

Cyclura is a genus of lizards in the family Iguanidae, with ten species of rock iguanas that occur on islands in the West Indies.
They are known for their thick, ringed tails, which give them their common name of cycluras or more commonly as rock iguanas.

Cyclura iguanas are herbivorous, cold-blooded, and have a high degree of endemism, with (in most cases) a single species or subspecies originating on an individual island.
They inhabit subtropical zones, of Caribbean island dry forest biomes, and prefer rocky areas, steppes, and light forests.

Cyclura iguanas are also known for their longevity, as some species can live up to 40 years or more in captivity.
They are sexually dimorphic, with males being larger than females and having larger dorsal crest scales, femoral pores, and bodies.
Older males develop two conspicuous bumps on the back of their head, which are used for head-butting during territorial disputes.

Unfortunately, Cyclura iguanas are also known for being endangered or critically endangered, as they face many threats from habitat loss, invasive species, hunting, and poaching.
Some species, such as the Jamaican iguana, are considered to be among the most threatened reptiles in the world.
Conservation efforts are underway to protect and restore these unique and charismatic lizards.

Cyclura is a genus of lizards that are commonly known as rock iguanas.

They are endemic to islands in the West Indies, such as Cuba, Jamaica, Hispaniola, the Bahamas, the Cayman Islands, and the Turks and Caicos Islands.

Rock iguanas inhabit subtropical zones of Caribbean island dry forest biomes.

They are herbivorous and feed on fruits, flowers, leaves, and cacti.

They have thick, ringed tails and spiked jowls, and males are larger than females.

Rock iguanas are one of the most endangered groups of lizards, due to habitat loss, invasive species, hunting, and poaching.

They are protected by international laws and conservation programs, and some subspecies have been successfully bred in captivity.

The Cyclura is a genus of lizards that are also known as rock iguanas.
They are found only on islands in the West Indies, where they have a high degree of endemism.
They are among the largest lizards in the Caribbean, with thick tails, spiked jowls and a herbivorous diet.
Cyclura often live in rocky habitats with sparse vegetation and sun themselves on exposed surfaces.
It is vulnerable to habitat loss, invasive species and hunting.
Some species nest in sites excavated by crocodiles or near prickly-pear cacti for protection.
They are one of the most endangered groups of lizards in the world, but some conservation efforts have been successful.
The Cuban iguana is one of the ten species in this genus.
