Species Description: Ctenosaura pectinata

Common Name: Ctenosaura pectinata
Scientific Name: Ctenosaura pectinata

Habitat

The Ctenosaura pectinata, also known as the spiney-tailed iguana, primarily inhabits the warm coastal areas of the Pacific coast of Mexico, particularly in states like Sinaloa and Nayarit. This species thrives in diverse environments including tropical and subtropical dry forests, arid scrublands, and rocky outcrops, favoring habitats with abundant shelter and areas to bask in the sun.

Physical Characteristics

The spiney-tailed iguana can reach a substantial length of up to 70 centimeters (about 27 inches). Its physical attributes include a robust, elongated body with a distinctive spiny tail, which serves as a defense mechanism against predators. They are characterized by their grayish to olive-green coloration, often with lighter bands or stripes. Adult males tend to be larger and display more vibrant colors than females, especially during the breeding season.

Behavior

Ctenosaura pectinata exhibits a variety of interesting behaviors. These iguanas are known for their basking habits, often seen sunning themselves on rocks or branches to regulate their body temperature. They are diurnal and lead a semi-arboreal lifestyle, showcasing agility both on the ground and in trees. They also exhibit territorial behaviors, especially males, using vocalizations and displays to assert dominance.

Diet

The diet of Ctenosaura pectinata predominantly consists of a herbivorous menu, including leaves, flowers, fruits, and occasionally small insects. They are known to forage on various plants, making them important herbivores in their ecosystem, helping in seed dispersal and maintaining plant diversity.

Reproduction

These iguanas typically breed from May to July, with females laying clutches of 5 to 15 eggs in dug burrows. The incubation period lasts approximately 60 days, and the hatchlings emerge in late summer. Parental care is minimal, with young iguanas quickly becoming independent.

Conservation Status

The conservation status of Ctenosaura pectinata is currently listed as Vulnerable on the IUCN Red List. Habitat loss due to human activities such as deforestation and urban development, coupled with the illegal pet trade, poses significant threats to their population. Conservation efforts are crucial to preserving this unique species.

Interesting Facts

One fascinating aspect of Ctenosaura pectinata is its remarkable ability to adapt to various habitats within its geographic range. Additionally, these iguanas are known for their impressive climbing skills, allowing them to escape predators by retreating into trees and shrubs.

Role in Ecosystem

Ctenosaura pectinata plays a vital role in its ecosystem as a herbivore, contributing to the balance of plant life. Their feeding habits help in the pollination of various plant species and their presence in the food chain supports a variety of predators, thus maintaining ecological harmony.
