Green iguanas are found distributed from Mexico to Brazil and are largely arboreal. Being almost entirely vegetarian they do occasionally eat carrion and insects and can grow up to 6 feet. The green iguanas have a white photo sensory organ on the top of their heads called parietal.
This “third eye” cannot form images but is sensitive to change in light and helps detect movement. They breed during the dry season and the females lay around 20 – 50 eggs. Iguanas are one of the most popular animals for pets in the US, despite being hard to take care of. This reduces their lifespan as they are not cared for properly or set free or given to reptile rescue groups. The iguanas in the Madras Crocodile Bank have names – the green one which is the male is called Caesar and the rust one, the female is Monty.
