Species Description: Cyclura nubila

Common Name: Cyclura nubila
Scientific Name: Cyclura nubila

Habitat

Cyclura nubila, commonly known as the Cuban rock iguana, is primarily found in the dry, rocky areas of the Caribbean islands, particularly on the islands of Cuba and the Bahamas. These iguanas thrive in tropical and subtropical environments, inhabiting coastal scrublands, limestone rock formations, and vegetation zones that provide ample shelter and food sources.

Physical Characteristics

This impressive species can grow up to 4.5 feet in length, showcasing a robust build and a distinct coloration that often ranges from gray to brown, with patches of green. Their skin is covered in tough, spiny scales, and they possess prominent dorsal crests. A notable feature includes their long tails and strong limbs, which aid in their agility over rocky terrains.

Behavior

Cyclura nubila exhibits diurnal behavior, being most active during the day when they can be observed basking in the sun. These iguanas are known for their territorial nature and can often be seen engaging in social displays. They communicate through a variety of body language and vocalizations, particularly during mating season.

Diet

The Cuban rock iguana is primarily herbivorous, feeding on a diverse diet that includes leaves, fruits, and flowers. They are known to consume various plant species, making them a fundamental part of their ecosystem. Their feeding habits highlight their role in seed dispersal, as they often eat ripe fruits and excrete the seeds in different locations.

Reproduction

Cyclura nubila typically breeds during the warmer months, with the mating season generally occurring from March to June. Females lay clutches of 5 to 30 eggs in sandy burrows, which they carefully excavate to protect from predators. The hatchlings emerge after about 60 days, and the survival of the young iguanas can depend on environmental factors and predation.

Conservation Status

Cyclura nubila is currently classified as endangered on the IUCN Red List. Factors contributing to their decline include habitat loss, invasive species, and poaching. Conservation efforts are crucial in protecting their natural habitats and ensuring the continuation of this majestic species.

Interesting Facts

Did you know that Cyclura nubila can hold their breath underwater for several minutes? This adaptation allows them to escape threats by diving into the water. Additionally, they are known for their social structure, forming groups known as ‘pods’ during certain times.

Role in Ecosystem

Cyclura nubila plays a vital role in its ecosystem as a herbivore and a seed disperser. By consuming a variety of plants and fruits, they contribute to plant diversity and health in their habitats. Furthermore, they serve as prey for larger predators, thus maintaining the balance within the food web.
