Common Name: Cyclura rileyi

Scientific Name: Cyclura rileyi

Habitat:

Cyclura rileyi, commonly known as the Grand Cayman blue iguana, is primarily found in the Cayman Islands, specifically on Grand Cayman. This species thrives in a range of environments, including dry forests, limestone scrublands, and coastal areas, where it prefers warm temperatures and ample sunlight. The iguana’s habitat primarily consists of shrubland and rocky terrains that provide essential shelter and food sources.

Physical Characteristics:

Cyclura rileyi typically grows to an impressive size, reaching lengths of up to 5 feet (1.5 meters) and weighing between 15 to 30 pounds (6.8 to 13.6 kg). They are characterized by their distinctive blue-gray coloration, particularly in adult males, which sets them apart from other iguana species. Their robust, stocky bodies feature a strong tail and prominent spines along their backs, making them easily recognizable.

Behavior:

This species exhibits a range of interesting behaviors. Cyclura rileyi is primarily diurnal, meaning they are most active during the day. They are often seen basking in the sun to regulate their body temperature. Socially, these iguanas can be territorial and engage in displays to assert dominance. Males often engage in head-bobbing and other visual signals during the mating season.

Diet:

Cyclura rileyi is herbivorous, feeding primarily on leaves, fruits, and flowers. Their diet consists of native plants, including various fruits like figs and wild guavas. Watermelon and other cultivated fruits are also consumed when available. This diet is crucial for their growth and overall health, highlighting their role as seed dispersers within their ecosystem.

Reproduction:

The breeding season for Cyclura rileyi typically occurs from March to August. Females lay clutches of 10 to 15 eggs, which they bury in the ground to protect them from predators. The eggs incubate for about 60 to 80 days before hatching. Hatchlings are independent from birth, showcasing a remarkable adaptation for survival in the wild.

Conservation Status:

Cyclura rileyi is currently classified as endangered on the IUCN Red List. Habitat destruction, invasive species, and human activities pose significant threats to their survival. Conservation efforts are ongoing to protect this unique species and its natural habitat.

Interesting Facts:

Cyclura rileyi can live for over 50 years, making them long-lived inhabitants of their ecosystems. They are also known for their ability to change color slightly with temperature variations, which helps them manage their body heat more effectively. Furthermore, these iguanas have a unique social structure that allows them to maintain harmonious relationships within their populations.

Role in Ecosystem:

Cyclura rileyi plays a crucial role in its ecosystem as a herbivore, aiding in the maintenance of plant health and contributing to seed dispersal. By feeding on various plants, they help regulate vegetation growth, further contributing to the biodiversity of their habitat. This interaction highlights their importance in the ecological balance of the Cayman Islands.
