Iguanas are fascinating reptiles, known for their vibrant colors and unique behaviors. One question many iguana owners have is about their ability to stay underwater. This article explores the details of how long an iguana can stay underwater, including their natural habitat, physiology, and survival mechanisms.
Understanding Iguana Habitat and Behavior
Iguanas are native to tropical areas. They are found in Central and South America, including countries like Mexico, Costa Rica, and Brazil. In their natural habitat, iguanas are often seen near water sources such as rivers, lakes, and coastal areas.
Aquatic Adaptations of Iguanas
Iguanas are semi-aquatic animals. They have adapted to living both on land and in water. These adaptations include webbed feet, which help them swim efficiently. Their bodies are streamlined for movement in water. Additionally, iguanas can close their nostrils to prevent water from entering their respiratory system.
Iguanas’ Underwater Breathing Capabilities
Unlike some aquatic reptiles, iguanas are not fully adapted to underwater living. They have the ability to hold their breath for extended periods, but they must eventually come up for air. The length of time an iguana can stay underwater depends on several factors.
Factors Affecting Underwater Duration
Species Differences
Different iguana species have varying abilities to stay underwater. For example, the Green Iguana (Iguana iguana) is more accustomed to swimming and can hold its breath longer compared to other species. The Marine Iguana (Amblyrhynchus cristatus) from the Galápagos Islands is highly adapted to underwater life and can stay submerged for longer periods.
Size and Age
Larger and older iguanas generally have better endurance underwater compared to smaller and younger ones. This is because larger iguanas have more body mass and better-developed respiratory systems.
Health and Condition
The health of an iguana significantly affects how long it can stay underwater. Healthy iguanas can hold their breath longer than those suffering from illness or stress. Regular check-ups with a veterinarian help ensure their overall well-being.
Water Temperature
The temperature of the water can influence how long an iguana can stay submerged. Iguanas are ectothermic, meaning their body temperature depends on the external environment. Colder water temperatures can slow their metabolism, affecting their underwater endurance.
Typical Duration for Underwater Breathing
On average, iguanas can stay underwater for about 20 to 30 minutes. However, this duration can vary based on the factors mentioned above. Some iguanas may only manage to stay submerged for 10 to 15 minutes, while others, particularly those in colder climates, may stay underwater for a shorter time.

Survival Mechanisms of Iguanas Underwater
Iguanas have developed several survival mechanisms to manage their time underwater.
Bradycardia
When an iguana dives underwater, its heart rate slows down. This process, known as bradycardia, helps conserve oxygen and prolong the time it can spend submerged.
Oxygen Management
Iguanas have efficient lungs and can manage their oxygen intake effectively. They take deep breaths before diving to ensure they have sufficient oxygen stored for their time underwater.
Behavioral Adaptations
Iguanas often use their underwater time to escape predators or navigate their environment. They are known to dive quickly and stay submerged to avoid threats.
Emergency Situations and Iguanas
In some cases, iguanas might find themselves in emergency situations where they need to stay underwater longer than usual. This can occur in captivity if they are frightened or during sudden environmental changes. It’s crucial to monitor their behavior and ensure they have access to a suitable environment that mimics their natural habitat as closely as possible.
Conclusion
In conclusion, iguanas can stay underwater for approximately 20 to 30 minutes on average, though this can vary based on species, size, health, and environmental conditions. Understanding their natural behaviors and providing a suitable habitat helps ensure their health and longevity. By observing these guidelines, iguana owners can help their pets thrive in both land and water environments.
This article has explored the factors affecting how long iguanas can stay underwater and the mechanisms they use to manage their time submerged. With proper care and attention, iguanas can enjoy a healthy and balanced life in their natural and captive environments.
FAQs
1. How long can water lizards stay underwater?
The Water Dragon is more often heard than seen as it dives into the water when disturbed. It can remain submerged for around one hour.
2. Is it OK to touch iguanas?
As iguanas can carry salmonella, individuals should avoid handling the reptiles and instead call professional removal services.
3. What is the lifespan of an iguana?
Iguana lifespan: The lifespan of iguanas varies greatly depending on whether they are wild animals or captives. A pet iguana will usually live between 15 to 20 years, but in nature, these animals don’t usually live past eight years. As such, it’s essential to keep in mind that iguanas are a long-term commitment.
4. Do iguanas recognize their owners?
Many people unfamiliar with iguanas don’t realize it, but pet iguanas absolutely recognize their owners by sight and sound. Iguanas have very keen vision and clearly see their owners and recognize them. Iguanas also hear well.
5. How to tell if an iguana is happy?
It’s easy to tell when an iguana is calm and content they will look relaxed, their dewlap will be down and they tend to lick things a lot, this is not only a sign of being relaxed but also happy and even curious. Understanding your iguana is key in getting to know them and their personalities.
