How long can a pet turtle stay underwater?

Turtles are highly aquatic and are well-equipped to stay underwater for long periods of time. They do this by holding their breath, and some turtles can even breathe through their bottoms!

The length of time a turtle can hold its breath depends on the species, its age, and the temperature of the water. Most pet turtles will only stay underwater for a few minutes at a time, but some can stay underwater for much longer. For example, the leatherback sea turtle can hold its breath for just over seven hours.

Turtles are "cold-blooded" or ectothermic, which means they warm their bodies with the help of external sources like sunlight and warm water. Their metabolic rate is usually low compared to warm-blooded animals, but it does fluctuate with the temperature. In warmer temperatures, their metabolism speeds up, and they need more oxygen.

Some turtles, like snapping turtles and painted turtles, can survive in low-oxygen waters by using anaerobic metabolism and active chemical buffering processes. Other turtles can absorb oxygen directly from the water via specialised structures in their throats and cloaca (or butt!). This is known as cloacal respiration.

Freshwater turtles can sleep underwater for several hours. They are able to do this because their metabolism slows down during sleep, meaning they need less oxygen.

The skull of a sea turtle is designed for submerged feeding. They suck food and water into their mouths by quickly extending their head and neck. They then spit out the water and swallow the food.

How does a turtle's metabolism affect its breath-holding ability?

A turtle's ability to hold its breath underwater is influenced by several factors, including its metabolism, which is linked to its body temperature. As ectothermic or "cold-blooded" reptiles, turtles' body temperatures are determined by their environment. This means that their metabolism is influenced by the temperature of the water they inhabit.

When the water is cool, a turtle's metabolism slows down, resulting in a decreased heart rate and respiration rate. This reduced metabolic rate means they require less energy and oxygen to survive. Conversely, in warmer temperatures, a turtle's metabolism speeds up, leading to an increased need for oxygen.

During periods of cold temperatures, turtles can enter a state of brumation, which is similar to hibernation in mammals. During brumation, turtles can survive with minimal oxygen intake, and they resort to cloacal respiration, also known as "butt-breathing," to obtain the oxygen they need.

The metabolic rate of turtles is generally lower compared to warm-blooded animals, but it does fluctuate with the temperature. At room temperature, many species can hold their breath for an average of 40 to 60 minutes. However, when resting or sleeping underwater, they can stay submerged for several hours.

The leatherback sea turtle (Dermochelys coriacea), which frequents cold waters, holds the record for the longest breath hold, spending just over seven hours underwater. This exceptional breath-holding ability can be attributed to its ability to lower its metabolic rate in colder temperatures.

In summary, a turtle's metabolism is influenced by its body temperature, which is dependent on the surrounding water temperature. This metabolic rate directly impacts the turtle's oxygen consumption, with slower metabolisms resulting in reduced oxygen requirements. Therefore, turtles can hold their breath longer in colder temperatures, allowing them to stay submerged for extended periods.

How do turtles breathe while underwater?

Turtles are reptiles and, as such, are ectothermic or "cold-blooded". This means that a turtle's body temperature is determined by its environment. If the water they are in is at 60 degrees F, their body temperature is also 60 degrees F. As a result, a turtle's metabolism is dependent on its body temperature. When the temperatures are cool, a turtle's metabolism is slow, and when the temperatures are warm, its metabolism is faster. The faster the metabolism, the more oxygen a turtle needs.

Turtles cannot breathe underwater and will drown if they are unable to surface for air. However, they have developed the ability to hold their breath for extended periods. At room temperature, many species can hold their breath for an average of 40 to 60 minutes. Some turtles can survive underwater for a few minutes, while others can survive for several hours. The leatherback sea turtle, for example, holds the record for holding its breath, spending just over seven hours underwater.

Turtles can also supply their own oxygen by breathing through their nostrils. However, they can also breathe through their cloaca, also known as "butt-breathing" or cloacal respiration. The cloaca is a single opening in the body from which digestive wastes, nitrogenous wastes, and reproductive products are released. In some turtles, there are two sac-like extensions on the sides of the cloaca, lined with tiny finger-like villi that are loaded with blood vessels. These extensions serve to exchange oxygen and carbon dioxide between the bloodstream and the water.

How does water temperature impact a turtle's breath-holding ability?

The breath-holding ability of turtles is influenced by various factors, including species, age, and water temperature. While the impact of species and age is significant, water temperature plays a crucial role in determining how long a turtle can stay underwater.

Turtles are ectothermic or "cold-blooded" animals, which means their body temperature is dependent on external sources like warm water and sunlight. As the water temperature changes, so does the turtle's body temperature, directly influencing their metabolic rate. When the water is warm, a turtle's metabolism speeds up, requiring more oxygen. Conversely, in cooler temperatures, a turtle's metabolism slows down, reducing its oxygen needs.

During winter, when water temperatures drop, turtles enter a state of brumation, similar to hibernation in mammals. This metabolic slowdown enables turtles to survive with minimal oxygen intake. They achieve this by utilising cloacal respiration, also known as "butt-breathing," where they absorb oxygen from the water through body surfaces rich in blood vessels, especially their cloaca or butt.

The impact of water temperature on a turtle's breath-holding ability is evident in the case of sea turtles. Sea turtles can typically hold their breath for a few hours while sleeping. However, when the water gets cold, they can remain underwater for much longer. For example, a loggerhead turtle submerged in cold water in Greece stayed underwater for seven hours, the longest recorded submersion for a wild sea turtle.

Additionally, certain species of freshwater turtles, such as snapping turtles and painted turtles, can tolerate extremely low oxygen levels in cold water by switching to an oxygen-independent metabolism. This adaptation allows them to survive forced submergence in cold water for over 100 days in laboratory conditions.

In summary, water temperature significantly influences a turtle's breath-holding ability. Colder water temperatures lead to a slower metabolism, reducing oxygen requirements, while warmer temperatures increase metabolic rates and oxygen consumption. These physiological adaptations allow turtles to survive underwater for extended periods, showcasing their remarkable ability to adapt to their aquatic environments.

How does a turtle's heart rate change when submerged?

The heart rate of turtles changes when they are submerged in water. When submerged, turtles experience a phenomenon known as "diving bradycardia", where their heart rate drops significantly. This allows them to conserve oxygen and stay underwater for prolonged periods.

During voluntary dives, the heart rate of green turtles was observed to be generally low at 11.1 beats per minute, but they often exhibited extreme tachycardia, with heart rates reaching up to 78.4 beats per minute. The heart rate of loggerhead turtles also decreased when submerged, with a mean heart rate of 12.8 beats per minute during dives, compared to 20.9 beats per minute during surface periods.

The intensity of diving bradycardia can vary depending on the depth of dives, dive duration, and underwater exercise. For example, heart rate typically drops further during deeper and longer dives. Underwater activity, such as swimming, can also influence heart rate. During underwater feeding, loggerhead turtles had a significantly higher heart rate than when they were resting or diving, as they moved almost continuously.

In summary, the heart rate of turtles does change when they are submerged, and this change is influenced by factors such as dive depth, duration, and level of activity.
