BLACK SPINY-TAILED IGUANA
Ctenosaura similis
DESCRIPTION
Black Spiny-tailed Iguana (Ctenosaura similis) is commonly known as the Central American Spiny-tailed Iguana. This species is characterized by its robust body, long tail, and distinctive spiny scales along its back, which can appear black or dark gray. They are primarily terrestrial and are known for their agility and speed, often basking in the sun on rocks or tree branches while being vigilant for predators.
FUN FACTS
- Black Spiny-tailed Iguanas are known for their impressive climbing abilities, often seen scaling trees and rocky surfaces with ease
- They can also shed their tails as a defense mechanism, allowing them to escape predators while the detached tail continues to move, distracting the threat.| These iguanas have a unique social structure, where males establish territories and engage in displays of dominance, such as head-bobbing and tail waving, to attract females and ward off rivals
