Green iguanas are known to be competent swimmers, and they can hold their breath for about 30 minutes to an hour when submerged in water. However, this duration greatly depends on factors like the individual iguana’s health, age, and environmental conditions.
If an iguana feels threatened, it may dive underwater to escape predators, demonstrating its remarkable ability to remain submerged. While they are primarily terrestrial reptiles, they navigate aquatic environments with ease and can use their ability to hold their breath to evade danger.
Keep in mind that while iguanas can stay underwater for extended periods, they naturally prefer to bask in the sun and enjoy a warm, dry environment. So, while they have this impressive ability, they do not rely on staying underwater as a regular part of their behavior or lifestyle.
