The Americas are home to the vast, attractive green iguana. Despite their name, green iguanas may be found in various hues. They may be green, purple, crimson, orange, black, or even reddish brown in hue. They may also have bright blue patterns and be bluish in hue. Green iguanas are protected from predators by a row of spines that runs up their backs and along their tails.
Their whip-like tails may be used to inflict piercing blows, and like many other lizards, an iguana can let its tail break if captured, allowing it to flee and grow a new tail. Iguanas also have a well-developed dewlap that aids in controlling their body temperature. In territorial displays and courtships, this dewlap is utilized.
Did you know?
- Green iguanas have excellent vision, enabling them to detect shapes and motions at long distances.
- Green iguanas have a white photosensory organ on the top of their heads called the parietal eye. It is also called the third eye, pineal eye, or pineal gland. This “eye” cannot form images but is sensitive to changes in light and dark and can detect movement. This helps the iguana detect predators stalking it from above.
- Green iguanas have very sharp teeth that are capable of shredding leaves and even human skin.
