The Cuban rock iguana is one of the world's most impressive iguanas. It is also one of the largest, with adult males sometimes reaching lengths of 4 or 5 feet and weights of nearly 7 kilograms. As its name implies, the Cuban rock iguana is found on the island of Cuba. This species (as well as all other members of the Cyclura) are vulnerable due to their remote island habitats. Most Cyclura iguanas are listed as threatened or endangered.

The Cuban rock iguana is being kept in private collections in increasing numbers, and for good reason. Their large, impressive appearance make them a very desirable species to own. Many Cuban rock iguanas are very tame, as well, and make good pets.

This species does best when housed in large, outdoor enclosures that allow it access to natural sunlight and high temperatures. A heated hidebox allows for thermoregulation during cool evenings and days. The Cuban iguana does best on a vegetarian diet consisting of collard greens, romaine lettuce, mustard greens, squash, parsley, figs, papaya and mango.
