Meet the iguanas: fascinating lizards thriving in tropical regions of the Western Hemisphere. Recognizable by their robust build, warty, scaly skin, striking back spines, and distinctive dewlap under their necks, these creatures are a sight to behold.
The name “iguana” has its roots in the Taino language, where “iwana” specifically describes these lizards in the Caribbean.
Iguanas are not just intriguing in appearance; their calm demeanor has made them beloved pets in the U.S. Yet, in the wild, many iguanas are endangered species that face threats, with some dangerously close to extinction.

The males often display dark gray to brick red hues, while the females usually show off in shades of olive green with dark stripes or bands.
3. Desert Iguana
The Desert Iguana, a native to the dry landscapes of Mexico, California, is a true desert dweller, spending its days on the sandy ground and sun-warmed rocks.
They are often the only lizards active during the scorching midday sun, making them one of the most heat-tolerant reptile species in North America.
Sporting a unique color palette of white, dark gray, and reddish-brown tones, the Desert Iguana blends seamlessly into its arid surroundings.
Keeping one as a pet can be challenging, as these lizards are known for their finicky eating habits, sometimes refusing even the most tempting treats like edible flowers.
4. Rhinoceros Iguanas
The Rhinoceros Iguana, named for the distinctive horn-like protrusions on the males’ snouts, is an endangered species coveted by many for its striking appearance. Hailing from Haiti and the Dominican Republic, these iguanas favor the dry, rocky, and forested coastal areas.
Their grayish-brown to black coloring provides excellent camouflage against predators in their natural habitats.
While Rhinoceros Iguanas can be known for their aggressive behavior, it’s important to note that temperament can vary greatly among individuals.
These impressive lizards have a notable lifespan, often living for more than 20 years.
5. Northeastern Spiny-tailed Iguanas

Though primarily herbivorous, feasting on fruits, flowers, leaves, and stems, they won’t shy away from consuming smaller animals, eggs, and arthropods when available.
Growing up to three feet in length, these iguanas are known for being nervous and defensive, often resorting to biting when threatened.
For those considering keeping a Northeastern Spiny Tail Iguana as a pet, it’s crucial to provide a large vertical enclosure to accommodate their climbing instincts and ensure their well-being.
6. Chuckwallas

Chuckwallas are typically gray with lighter-colored blotches across their bodies. These lizards have a robust build and can grow up to 6.3 inches in length.
They are suitable for experienced keepers in captivity, provided they have a spacious, rocky environment.
As omnivores, Chuckwallas have a diverse diet, including vegetables, seeds, and insects. In captivity, they can be maintained on a strictly herbivorous diet, adapting well to a variety of plant-based foods.

The males are particularly eye-catching with their blue or green stripes, while females typically display a solid color.
Adapted to an arboreal lifestyle, these lizards spend most of their time in trees, favoring regions with lush vegetation and tall trees. They reach a length of about 7.5 inches and are adept swimmers.
Fiji Banded Iguanas primarily feed on leaves, flowers, and fruits, occasionally consuming insects.

These iguanas can grow to an impressive six feet in length and are characterized by their sturdy bodies and short, strong legs. Adults are adorned with a spine-lined row running from their neck to the tail.
Their coloring ranges from black or gray, with lighter dorsal stripes and males often display brighter hues during the breeding season.
Remarkably adapted to their environment, Marine Iguanas primarily feed on sea algae, diving to considerable depths to forage. Living in colonies along the rocky coasts, they are often spotted basking in the sun, warming up after their swims in the cool ocean waters.

Jamaican iguanas are striking reptiles known for their scaly skin and lengthy tails adorned with triangular stripes along their spines. Their scales display a beautiful spectrum of colors, from shades of gray to hues of blue and green.
These iguanas hold the distinction of being the largest native animals in Jamaica, showcasing the island’s unique biodiversity.
The Jamaican Iguana is critically endangered due to habitat loss and invasive species. Once widespread along Jamaica’s southern coasts, the Jamaican Iguana now finds refuge only in the Hellshire Hills, a dry forest area rich in limestone and other rocks.
Adapted to this environment, the iguana uses its long toes and sharp claws to expertly climb trees, where it feeds on leaves, fruits, and flowers.
Although largely herbivorous, these iguanas will also consume insects, snails, and small animals when they’re available, showcasing their adaptability in the diet.
10. Bahamian Rock Iguanas
Rock iguanas are sizable lizards, and the Bahamian variety typically showcases various shades of brown. They commonly measure between two and a half to three feet in length, making them quite prominent among the reptilian inhabitants of their habitats.
The Bahamian Rock Iguanas are not only stunning in appearance but also among the world’s most endangered lizards. They play a significant role in the Bahamas’ tourism industry, drawing visitors eager to witness these majestic creatures in their natural habitat.
As herbivores, Bahamian Rock Iguanas thrive on a diet of leaves, flowers, berries, and fruits. Their physical build, characterized by long, straight tails and short, robust limbs, makes them adept at climbing trees and navigating rocky terrains.
Additionally, these iguanas are surprisingly proficient swimmers in saltwater, adding to their list of remarkable adaptations.
