It’s a common misconception that alligators swallow large amounts of water while they feed. In fact, alligators have a unique adaptation that allows them to breathe while their mouths are submerged. This adaptation is called the glottis, and it is a small opening at the back of the throat that allows air to pass into the lungs while the mouth is closed. When an alligator submerges its head, the glottis closes, preventing water from entering the lungs. This allows the alligator to breathe while its mouth is underwater. Although they don’t swallow water, alligators can hold their breath for up to two hours.
In addition to the glottis, alligators also have a number of other adaptations that help them to survive in water. These adaptations include webbed feet, which help them to swim, and a thick layer of scales that protects their skin from the water. Alligators are also able to slow their heart rate and metabolism when they are submerged in water, which helps them to conserve energy. These adaptations make alligators well-suited for living in aquatic environments.
Despite their adaptations, alligators can still drown if they are submerged in water for too long. However, they are able to hold their breath for much longer than humans, and they can even sleep underwater. Alligators are fascinating creatures that have adapted to live in a variety of habitats. Their ability to breathe while submerged in water is just one of the many unique adaptations that allow them to survive in their environment.
How Alligators Avoid Swallowing Water
Alligators are remarkable creatures that have adapted to their aquatic environment in many ways, including their ability to avoid swallowing water when they open their mouths underwater. This is achieved through several ingenious mechanisms.
Firstly, alligators have a specialized flap of tissue called the glottis, which is located at the back of their throat. When the alligator opens its mouth underwater, the glottis closes tightly, sealing off the airway from the mouth cavity. This prevents water from entering the lungs, allowing the alligator to breathe while its mouth is submerged.
Additionally, alligators have a unique tongue structure that assists in preventing water ingestion. Their tongue is attached to the floor of their mouth, rather than the back of the throat as in most other animals. This arrangement allows the tongue to act as a barrier, further protecting the airway from water.
