Iguanas are fascinating creatures that have always intrigued humans with their unique features and abilities. One of the most common questions people ask about iguanas is whether they can breathe underwater.
To answer this question, we must first understand the biology of iguanas and their respiratory system. In this article, we will explore the science behind iguanas and their underwater abilities, debunking some common myths along the way. So, let’s dive in and discover whether iguanas can truly breathe underwater!
No, iguanas cannot breathe underwater as they are not equipped with gills. They are reptiles and require air to breathe through their lungs. However, iguanas have the ability to hold their breath for up to 30 minutes, which allows them to stay underwater for extended periods of time while hunting or escaping from predators.
Can Iguanas Breathe Underwater?
Iguanas are fascinating creatures that are native to the tropical regions of Central and South America. They are known for their impressive swimming abilities, but can they breathe underwater? In this article, we’ll explore the truth behind this common question.
Understanding the Anatomy of Iguanas
Before we dive into the question of whether or not iguanas can breathe underwater, it’s important to understand their anatomy. Iguanas have a unique respiratory system that allows them to breathe in a way that differs from other animals. They have a set of lungs that are divided into numerous small compartments, which allows them to extract more oxygen from the air they breathe.
Despite this unique respiratory system, iguanas are still air-breathing animals. They do not have gills like fish or amphibians, and they cannot extract oxygen from water in the same way that these animals can.
Can Iguanas Hold Their Breath Underwater?
While iguanas cannot breathe underwater, they are capable of holding their breath for extended periods. When they swim, they will often dive underwater to avoid predators or search for food. However, they cannot stay underwater for more than 30 minutes at a time.
During this time, iguanas will slow down their heart rate and reduce their bodily functions to conserve oxygen. This is known as bradycardia, and it allows them to stay underwater for longer periods without needing to breathe.
The Risks of Extended Underwater Time
While iguanas are capable of holding their breath for extended periods, there are risks associated with prolonged underwater time. If an iguana is unable to surface for air, they can suffer from hypoxia, which is a lack of oxygen in the body. This can lead to serious health issues, including brain damage and even death.
It’s important to note that iguanas are not adapted for underwater life, and they should not be kept in water for extended periods. While they are excellent swimmers, they still need access to air to survive.
Benefits of Swimming for Iguanas
While iguanas cannot breathe underwater, swimming still offers numerous benefits for these creatures. Swimming helps them to regulate their body temperature, which is important for iguanas that live in hot and humid environments. It also helps them to exercise and maintain a healthy weight.
Additionally, swimming can help to reduce stress in iguanas. These creatures are often kept in captivity, and swimming can provide them with a way to release pent-up energy and reduce anxiety.
Iguanas vs. Other Swimming Reptiles
Iguanas are not the only reptiles that are capable of swimming. Other species, such as turtles and crocodiles, are also excellent swimmers. However, there are some differences between these creatures and iguanas.
Turtles and crocodiles have adaptations that allow them to stay underwater for longer periods. Turtles, for example, can extract oxygen from water through specialized glands in their cloaca. Crocodiles also have a unique respiratory system that allows them to hold their breath for up to an hour.
The Bottom Line
In conclusion, iguanas cannot breathe underwater. While they are capable of holding their breath for extended periods, they still need access to air to survive. Swimming offers numerous benefits for iguanas, but it’s important to remember that they are not adapted for underwater life.
If you have an iguana as a pet, make sure to provide them with a safe and comfortable environment that allows them to swim and access air as needed. With proper care and attention, iguanas can thrive both on land and in water.
Freequently Asked Questions
Can iguanas breathe underwater?
Yes, iguanas are able to hold their breath underwater for up to 30 minutes. They have the ability to slow down their heart rate, lower their metabolism, and stop unnecessary movements in order to conserve oxygen. This adaptation allows them to stay submerged for longer periods of time.
However, it is important to note that iguanas are not aquatic animals and should not be kept underwater for extended periods of time. They need to breathe air in order to survive and may become stressed or develop health issues if forced to stay underwater for too long.
How do iguanas breathe when they are underwater?
When iguanas are underwater, they rely on a process called buccal pumping to breathe. This involves using their throat muscles to force air in and out of their lungs. The iguana will take a deep breath before diving underwater and then close its nostrils and mouth, relying solely on the oxygen it has stored in its lungs.
As the iguana uses up the oxygen in its lungs, it will begin to slowly release air through its nostrils and mouth. When it needs to take another breath, it will quickly swim to the surface and take in air before diving back down again.
Can iguanas survive in water?
While iguanas are able to hold their breath and swim underwater, they are not adapted to living exclusively in water. They are primarily land-dwelling animals and require access to both land and water in order to survive.
If an iguana is kept in water for too long, it may become stressed, develop respiratory issues, or even drown. It is important to provide iguanas with a proper habitat that includes both a water source and a dry basking area.
Do all iguanas have the ability to breathe underwater?
Yes, all iguanas have the ability to hold their breath and survive underwater for a period of time. This includes both wild and captive iguanas of all ages.
However, it is important to note that not all iguanas enjoy being in water. Some may be more hesitant to swim or may prefer to stay on land. It is important to observe your iguana’s behavior and preferences and provide it with a habitat that suits its needs.
How can I help my iguana swim safely?
If you want to provide your iguana with a swimming area, it is important to make sure that it is safe and appropriate for your pet. The water should be shallow enough for your iguana to stand in and should be free of any chemicals or debris.
You should also supervise your iguana while it is swimming and never leave it unattended. It is also important to ensure that your iguana has a way to climb out of the water and access a dry basking area. By following these guidelines, you can help ensure that your iguana stays safe and healthy while enjoying a swim.

In conclusion, iguanas are not able to breathe underwater. They are reptiles and they breathe oxygen just like humans do. Iguanas have a pair of lungs that help them breathe. If an iguana were to be submerged underwater, it would eventually drown as it cannot extract oxygen from water.
It is important to note that although iguanas cannot breathe underwater, they are still impressive creatures. Iguanas are known for their ability to hold their breath for up to 30 minutes while swimming. This allows them to forage for food and escape predators.
Overall, the idea of iguanas being able to breathe underwater is a common misconception. While they are excellent swimmers, they require air to survive and cannot extract oxygen from water. It is important for anyone who owns or interacts with iguanas to understand their respiratory system and needs to ensure their well-being.
