Can Turtle Breath Underwater

Turtle cannot breathe underwater. They have to come up to the surface to inhale air

because they breathe through the external nares located above their mouth. However,

turtles can hold their breath for long time underwater. This gives a false impression that they

are breathing underwater.

Now that you know turtles cannot breathe in the water, let’s also understand how turtles

breath and how long they can hold their breath underwater.

But first, let us understand why turtles cannot breath underwater

 

 

 

Why Turtles Cannot Breathe Underwater ?

 

Although turtle are aquatic, They are primarily land creatures.

Unlike fish that need to constantly stay in the water to survive and live, Turtle need to come

to the water surface to breathe air.

Having said that, there are some freshwater turtles that can absorb oxygen from the water

through the internal walls of their Cloaca or anus

They breathe in this manner during their hibernation period

Now, even if most of the turtles cannot breathe underwater, they can stay underwater for a

long time.

They can remain submerged in water during winter by lowering their hearth  rate and living

off their body fat.

 

Okay, if turtle cannot breath underwater, then how do they breath ? let’s talk about now 

 

 

How Do turtle Breathe?

 

To get oxygen, Turtles breathe air through the external nares that are located above their

mouth.

When they breathe, air move into the trachea through the glottis.

The trachea of the turtle is elongated and is also flexible that is why a turtle can move its

head in and out of the shell

The trachea splits into two bronchi near the heart to delivery the air to the lungs.

 It is through the lung that the oxygen from the air is absorbed into the turtle’s body.

However, the turtle shell is hard, and it cannot expand and contact to help the turtle in

breathing.

But, the turtle’s shell help in moving the air in and out of the lungs.

Turtles also move their limbs, which helps them in breathing by altering the pressure in the

lungs

Alright coming back to the breath underwater, you just saw that turtle can hold their breath

underwater. But for how long?

 

 

How Long can turtle hold their breath underwater?

 

Turtle are fascinating creature. They can hold their breath underwater for prolonged periods

Different species of turtles have different capacity to hold their breath.

Some turtles can their breath for as short as 30 minutes underwater while other turtle

species, such as sea turtle, can stay underwater for hours without coming up to the surface

to breathe

During routine activities, turtles can hold their breath for 45 minutes to 1 hour

How ever, they usually dive for 5 minutes, and then in between the dives, they come to the

surface to breathe air for few second.

Painted turtles or pet slider can swim underwater for an extend periode too 

The majority of the pet turtles sleep underwater at the night.

They come out of the water only a few time to breathe and then resume sleeping

They increase their rate of blood flow to absorb more oxygen while breathing.

Matama ( Chelus ) are freshwater turtles that reside in river, pond and sluggish backwaters.

Their can hold their breath underwater for about an hour.

They remain still in murky water sometimes for more than an hour to grab prey for their

meal.

Surfacing out to breathe ruin their chance of catching the fish or other prey that comes near

them because the prey then become aware of the turtle’s presence.

So many times, these turtles remain motionless and hold their breath for more than an hour

Sea turtles also cannot breathe underwater.

However,they can hold their breath for 4 to 7 hours underwater while resting or sleeping.

Okay! That was about turtles breathing underwater. But how do they breath when they are

hibernating?

Turtle use the but breathing technique when in hibernation. Let’s talk about this now.

 

 

How Do Turtles Breathe Underwater By Using The Butt Breathing Technique 

 

Several species of turtles remain submerged underwater for several months.

This happens particularly in winter when they hibernate. That is when they use the butt

breathing technique to survive .

During hibernation, turtles breath out of their butt. This term is called Cloacal respiration.

It is not exactly breathing, but they diffuse oxygen in and carbon dioxide out using their

cloaca.

During this period, turtle do not come out of the water to breathe. Instead, they extract

oxygen from water it self

They do this through cloaca as it has a high density od blood vessels that allows the turtle to

absorb oxygen from water through their skin.

As their metabolism rate is slow during hibernation, their need for oxygen also decreases 

So, the oxygen that is diffused from the water running over them is sufficient for them to

survive till spring.

 

 

Parting Thoughts

 

Turtles cannot breathe underwater. They need to come to the surface to breathe air, or else

they can drown.

However, they can stay underwater for long time.

Turtles breathe air just like humans. They breathe through the external nares above their

mouth.

And during hibernation, they use the cloacal respiration technique to take-in oxygen from

the surrounding water
