There are many unique characteristics of a snapping turtle. For instance, they can grow up to two feet and can live for a maximum of 100 years, provided they get good care. Before bringing this lovely creature home, ensure doing thorough research. That’s because they need special attention and care for ideal growth and health. 

This article highlights interesting facts about snapping turtles. From how it holds its breath underwater to whether or not it can survive without oxygen, learn plenty about this creature here. Anyone considering adopting a snapping turtle as a pet at home should read this article first. 

How Long Can A Snapping Turtle Hold Its Breath?

Research indicates that the average breath-holding time for snapping turtles is considerably variable, depending on numerous factors such as temperature, age, and activity level.

Under normal conditions, a snapping turtle can comfortably hold its breath for about 15 to 20 minutes.

However, these turtles are capable of reducing their metabolic rate, which allows them to extend this duration significantly under certain conditions.

Condition Average Duration Maximum Recorded Duration Notes
Normal Conditions 15-20 minutes 30 minutes Observed in controlled environments
Brumation (Cold Months) Up to 1 hour 3-4 hours Longest durations recorded in cold, oxygen-rich water
Post-feeding 10-15 minutes 25 minutes Reduced duration due to increased metabolic rate

Table 2: Physiological Mechanisms and Behavioral Implications

Mechanism Description Behavioral Implication
Anaerobic Metabolism Utilization of energy without oxygen during prolonged submersion Enables extended underwater endurance, especially during brumation
Cutaneous Respiration Oxygen absorption through skin and cloaca in water Facilitates oxygen intake in oxygen-scarce environments
Low Metabolic Rate in Cold Water Reduced energy and oxygen needs in colder temperatures Longer duration of breath-holding in winter months

Factors Influencing Breath-Holding Capacity in Snapping Turtles

The breath-holding capacity of snapping turtles is not a fixed attribute but varies depending on several environmental and physiological factors. Understanding these factors is crucial for both scientific understanding and conservation efforts.

1. Water Temperature

Water temperature plays a pivotal role in determining how long a snapping turtle can hold its breath. In colder water, turtles have a slower metabolism, which reduces their need for oxygen, thereby allowing them to hold their breath for longer periods. Conversely, in warmer water, their metabolic rate increases, shortening the breath-holding duration.

Water Temperature Effect on Breath-Holding
Cold (<10°C) Increased duration due to slower metabolism
Warm (>20°C) Decreased duration due to faster metabolism

2. Age and Size of the Turtle

The age and size of a turtle also impact its breath-holding capacity. Generally, larger and older turtles have a more developed capacity for holding their breath compared to younger, smaller ones.

Turtle Age/Size Breath-Holding Capacity
Juvenile Shorter duration
Adult Longer duration

3. Activity Level

The level of activity greatly influences how long a turtle can remain submerged without breathing. Active turtles, especially when hunting or evading predators, consume oxygen more quickly and thus have shorter breath-holding times.

Activity Level Breath-Holding Impact
High Activity Shorter duration
Low Activity Longer duration

4. Health and Stress Factors

The overall health and stress levels of a turtle can affect its respiratory efficiency. A healthy turtle in a stress-free environment will generally have a better breath-holding capacity than a stressed or unhealthy one.

Health/Stress Condition Effect on Breath-Holding
Good Health Optimal breath-holding capacity
Poor Health or Stress Reduced capacity

5. Environmental Oxygen Levels

The oxygen level in the water is a critical factor. Higher oxygen levels in the water allow for more efficient cutaneous respiration, thereby extending the time a turtle can stay submerged.

Water Oxygen Level Breath-Holding Impact
High Oxygen Longer duration
Low Oxygen Shorter duration

In conclusion, the breath-holding capacity of snapping turtles is a complex trait influenced by a multitude of factors. Understanding these can provide insights into their behavior, ecological needs, and responses to environmental changes. This knowledge is not only fascinating from a biological standpoint but also essential for the conservation and management of these unique reptiles.

How Do Snapping Turtles Breathe Underwater?

As mentioned above, snapping turtles have the ability to hold their breath underwater for an average of 30 minutes. But how can they manage to do so?

This is possible because of their unique adaptations. These little creatures consist of large lungs that enable them to store and retain oxygen. Their skin also allows seamless absorption of oxygen. That’s one of the main reasons why experts recommend keeping snapping turtle pets in clean water. 

When underwater, these pet turtles use their cloaca (butt) for breathing. Their butt consists of dense blood arteries. This helps them diffuse oxygen and carbon dioxide in and out of their body.  

Nevertheless, sometimes the cloacal (butt) breathing technique can become incapable of meeting the oxygen requirements of the turtle. For instance, the surface of lakes freezes during winter, making it difficult for them to use this breathing procedure. 

Let’s say the winter is harsh and cold. In that case, the pond or lake will have a limited oxygen supply. Thus, the snapping turtles won’t be able to extract sufficient oxygen from it. So, it may seem that these creatures have to breathe without oxygen. Is that even possible? Let’s find out in the next section. 

How Do Snapping Turtles Breathe During Hibernation?

With declining surrounding temperature, the metabolism of the snapping turtle slows down significantly. This is when their heartbeat falls down to 5 beats per minute. (Their normal heartbeat rate is 25 beats per minute). 

However, if the temperature degrades and falls even below, these creatures will start preparing themselves for hibernation. When doing so, the heartbeat of the snapping turtle falls down to 1 beat per minute. The lower metabolism of the turtle during winter lowers its oxygen requirements. 

Henceforth, these creatures will need considerably less amount of oxygen. Snapping turtles respire via their butt when the temperature is moderately cold (not freezing cold). The butt of these turtle species can absorb oxygen from the water through its dense blood vessels.

Oxygen gets entrapped within a pond or lake when it freezes due to extreme cold weather conditions. Consequently, the dire situation will make it next to impossible for these turtles to breathe oxygen inside the water. Nevertheless, these turtles adapted themselves quite well. 

Thanks to evolution and years of adaptation, snapping turtles can perform anaerobic respiration. Thus, they can break the glucose needed by their organs without the use of oxygen. However, as mentioned above, the extensive use of this method can be harmful to their health due to lactic acid deposits. 

Can Snapping Turtles Drown In Water?

Yes, snapping turtles–no matter whether baby or adult–can drown. They can drown for many reasons. Firstly, they can drown when the water in the tank is dirty. The dirty water can make breathing difficult for them, and thus, they may eventually drown. That’s why it’s crucial to always put clean water in the tank. 

Secondly, these creatures can drown when they get trapped or caught in a net. That’s why it’s crucial to be cautious and alert while handling them as a pet. 

Lastly, snapping turtles living in the wild can drown when they rely excessively on the anaerobic respiration method. That’s because it results in excess lactic acid deposit in the muscles, leading to cramps. The cramps make it difficult for them to stay in the water, and thus, they drown. 


To conclude, snapping turtles can hold their breath for as much as six hours and as little as 30 minutes. During hibernation, they can hold their breath for several months by switching to the anaerobic respiration procedure.
