No, iguanas do not have a third eye. In fact, the misconception that iguanas have a third eye is actually based on the presence of their parietal eye, which is located on the top of their heads and is also sometimes called the “third eye”.
This parietal eye is a light-sensing organ that is thought to help iguanas detect movement and potential predators. Unlike a true third eye, however, the parietal eye does not form images or contribute to the visual system.
It simply provides the iguana with a means of detecting light changes that may be caused by predators in the environment. Additionally, the parietal eye is relatively small and is covered in scales, unlike the eye of a true “third eye”.

How many eyes do iguanas have?
Iguanas have two eyes, which are set on either side of its head. Each eye is relatively large and shaped like a soccer ball cut in half. The pupils are vertically slit, similar to a cat’s eye. The eyes are fairly complex and contain three eyelids—an upper and lower lid and a nictitating membrane, which is an extra clear eyelid that will sweep from side to side to help the iguana clear debris from its eyes, keep moisture in its eyes, and protect its eyes from damage.
What does the third eye on an iguana do?
The third eye on an iguana is an organ located on the top of their heads that helps them sense changes in their environment. It is used to detect light and movement from predators, is important for regulating thermoregulation (body temperature), and is an important factor for their overall survival.
Through this “third eye,” iguanas can detect ultraviolet light and use it to monitor day length, aiding in their reproduction. They also use it to sense shadows and movement from potential predators.
The third eye is made up of a lens and a structure called the parietal eye that is surrounded by pigment and scales. The parietal eye is sensitive enough to detect changes in the amount of light falling on it, which the iguana then processes through its brain.
It is believed that the third eye helps iguanas distinguish between different environments and be more prepared for their surroundings.
Do 3 eyed animals exist?
Yes, 3 eyed animals do exist. Rare examples of 3-eyed animals have been reported in a variety of species such as amphibians, reptiles, birds, and mammals. For example, a three-eyed turtle was found in a pond in Mexico in 2011.
The turtle, nicknamed ‘Tres-Ojos’ or ‘Three-Eyes’, had a mutation of a third eye located on its forehead. Another three-eyed example was found in 2011 in Sweden — a European herbivorous deer with an extra ‘third-eye’ located in the middle of its head.
In addition to these cases, there have also been a few cases of 3-eyed cats, a 3-eyed chick, and a three-eyed snake found in various parts of the world. The causes of these abnormalities are generally attributed to genetic mutations or birth defects caused by environmental toxins.
Where is the bearded dragons third eye located?
The third eye of a Bearded Dragon is located on the top of their head between their eyes. It is often referred to as the Parietal Eye and it is a light sensitive spot. This organ is specialized for detecting changes in light that come from above and acts as an early warning system for predators.
It is made up of cells which are sensitive to various levels of light. These cells then send signals to the brain which help the Bearded Dragon assess their environment and identify potential threats.
In addition to detecting changes of light, the third eye can help the Bearded Dragon orient itself while basking in the sun. This organ is completely covered by scales and is not visible to the human eye.
What do you call an animal with 3 eyes?
An animal with three eyes is not well-documented in nature. There have been several instances of animals with extra physiological features reported throughout history, with descriptions spanning mythology, folklore, and observed cases of genetic mutation.
In mythology, tri-eyed creatures appear in multiple cultures around the world, often representing deities or gods of prophecy or wisdom. For example, in Greek mythology, the cyclops are one-eyed giants, while in Hindu mythology, the demon known as “Tri-Netra” is said to possess three eyes.
In Ancient Egypt, the god Horus was depicted with an extra eye in the center of his forehead — a spiritual representation of the sun.
In terms of observed cases, there have been numerous occurrences of three-eyed animals reported throughout history. Most cases involve metaplasia, a rare genetic mutation that can cause organs to develop abnormally.
This can often result in extra organs, such as an extra eye, or organs located in unusual parts of the body. These genetic mutations have been documented in multiple species, from horses to fish to amphibians.
Given the limited evidence of three-eyed animals in nature, there is no one term to explicitly describe an animal with three eyes. However, an animal with three eyes could be generally referred to as a “three-eyed animal.

Are there any mammals with 3 eyes?
No, there are no known species of mammals with three eyes. Although some reptiles, such as certain species of lizards and frogs, possess three eyes, no mammal species has been documented with three eyes.
It is possible that a three-eyed mammal has yet to be discovered or identified, but so far, none have been found. Other theories suggest that mutations resulting in three eyes have been observed in animals, but these have only been the result of specific environmental conditions, such as exposure to radiation, and are not indicative of an actual species having three eyes.
