The zoo has several green iguanas. Despite their name, green iguanas vary in color, they can be green, red or blue. Females are predominantly green, while male coloration depends on mood, temperature and social status. Their color helps them blend into their surroundings.
Interesting Fact: They have a photo-sensory organ on top of their heads called parietal eye or third eye. It does not work as an eye to capture images, but it captures changes in light and therefore motion.
