Iguanas are a diverse group of reptiles, with species native to tropical regions of North, Central, and South America and the Caribbean. Among the numerous species of iguanas, some of the more prevalent varieties include:

  • Green iguanas
  • Spiny-tailed iguanas
  • Rock iguanas
  • Desert iguanas

Each species has unique characteristics and care requirements, making it essential to consider their needs when selecting a pet iguana.

Green iguanas, for example, are popular pets but require advanced care, large enclosures, and high temperatures. The green iguana is native to Southern Brazil and Paraguay and is predominantly herbivorous.

On the other hand, spiny-tailed iguanas are fast-moving, nervous lizards with a less-than-ideal temperament. They belong to the Ctenosaura species and prefer rocky habitats with crevices and trees.

Rock iguanas, such as Cuban, Rhinoceros iguanas, and the Grand Cayman Blue Iguana, are large, ground-dwelling lizards with powerful jaws and unique coloration, suitable for experienced keepers. The rhinoceros iguana is particularly fascinating among them due to its distinctive features.

Desert iguanas are arid-dwelling lizards with white, dark grey, and reddish-brown scales. They can be challenging to care for but are suitable for experienced keepers with large desert-style terrariums.

Green Iguanas

Green iguanas are known for their impressive size, reaching 5-7 feet in length, and are a popular choice for pet owners. They typically display:

  • a green hue
  • blotches and stripes of other colors, such as orange, blue, black, and white
  • spines along their back
  • large dewlaps under their chins
  • noticeable jaws

Green iguanas from Brazil to Mexico are predominantly herbivorous, consuming leaves, flowers, berries, and fruits from various plant species. While their temperament can range from timid to nervous and defensive, regular handling and trust-building can help them become more comfortable around humans.

Spiny-Tailed Iguanas

Spiny-tailed iguanas, such as the black spiny-tailed iguana, are lizards with comb-like spines on their back and tail, providing a unique physical feature. The spiny-tailed iguana belongs to the Ctenosaura species and typically inhabits rocky habitats with crevices and trees.

Their diet consists of a variety of items, including:

  • fruits
  • flowers
  • foliage
  • small animals

Due to their protected status, wild imports of spiny-tailed iguanas are not available, and it is recommended to begin with captive-bred individuals when deciding to maintain spiny-tailed iguanas.

Rock Iguanas

West Indian Rock Iguanas, which include Cuban and Rhinoceros Iguanas, are large, ground-dwelling lizards with powerful jaws and distinct coloration. Most Rock Iguanas are characterized by their beefy build and well-defined features such as large spikes, wide jowls, and scaly skin. Brown, gray, and black are among the common colors. These colors form a part of most color palettes.

They primarily feed on vegetation. This includes:

  • leaves
  • flowers
  • berries
  • fruits from different plants

Once familiar with their environment and human keepers, Cuban rock iguanas tend to be relatively calm and curious, whereas Rhinoceros Iguanas can be quite aggressive.

The longest recorded lifespan of a captive-born Rock Iguana is 33 years.

Desert Iguanas

Desert iguanas, or the desert iguana, are small species native to arid regions of Mexico, California, and Arizona, typically inhabiting the desert floor and rocky areas in their habitat. They measure up to 18 inches in length, exhibiting white, dark grey, and reddish-brown scales across their cylindrical body.

While they can be particularly challenging to care for, as they may not readily accept food, even when offered something as appealing as edible flowers, desert iguanas are suitable for experienced keepers with large desert-style terrariums.
