Common Name: Ctenosaura nolascensis
Scientific Name: Ctenosaura nolascensis

Habitat

Ctenosaura nolascensis, commonly known as the Mexican Spinytail Iguana, is primarily found in the tropical dry forests of the Pacific coast of Mexico’s Baja California Peninsula. This species thrives in rocky, arid environments, often seen basking on sunlit rocks or foraging in nearby vegetation.

Physical Characteristics

This medium-sized iguana reaches lengths of up to 70 centimeters (27 inches), with males typically larger than females. Ctenosaura nolascensis is characterized by its distinctive spiny crest, which runs from its head to the tip of its tail. Their coloration varies from gray to greenish-brown, with banded patterns that provide excellent camouflage against predators.

Behavior

Ctenosaura nolascensis displays both diurnal and terrestrial behaviors, often seen sunbathing during the day and retreating to crevices or burrows at night. They are known for their impressive climbing abilities and can often be spotted resting in trees or shrubs. Their social structure includes territorial displays, especially among males during the breeding season.

Diet

This species is primarily herbivorous, feeding on a variety of plant materials, including leaves, fruits, and flowers. A significant part of their diet consists of native grasses and wild shrubbery. Occasionally, they may consume small insects, which provides them with essential nutrients.

Reproduction

The breeding season for Ctenosaura nolascensis typically occurs during the warm months, from May to August. Females lay between 4 to 15 eggs, which they bury in sandy substrates to incubate. Hatchlings emerge after approximately 60 to 90 days, and they are immediately independent, showcasing remarkable survival instincts.

Conservation Status

The current conservation status of Ctenosaura nolascensis is listed as vulnerable by the IUCN. This species faces threats such as habitat loss due to urban development and agriculture, as well as pressure from the pet trade.

Interesting Facts

Ctenosaura nolascensis can often be seen in the wild performing elaborate courtship displays. Not only is this species known for its unique physical characteristics, but it also plays a cultural role in various indigenous traditions of the region.

Role in Ecosystem

Ctenosaura nolascensis plays a crucial role in its ecosystem as both a herbivore and as prey for larger predators. By partaking in the seed dispersal process through its plant-based diet, it contributes to the health and regeneration of its natural habitat, thus ensuring biodiversity within the tropical dry forest ecosystem.
