How Can Sea Turtles Breathe Underwater? Turtles cannot breathe underwater.
They need to come to the surface to breathe air, or else they can drown.
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.
How long can a sea turtle stay under water? How long can sea turtles stay underwater
Do turtles breathe underwater or hold their breath? Their ability to “breathe” underwater is because of how their metabolism is affected by their body temperature, according to PBS News Hour. Like all reptiles, turtles are ectotherms, which means their body temperature is determined by their environment.
How do sea turtles get oxygen? Technically the term is cloacal respiration, and it’s not so much breathing as just diffusing oxygen in and carbon dioxide out, but the fact remains: when turtles hibernate, their main source of oxygen is through their butt.

Why can sea turtles hold their breath for so long?

Does a turtle have lungs?
Just like other reptiles, sea turtles have lungs. They have a slightly different structure than mammalian lungs, but work just as well when it comes to exchanging gases (oxygen and carbondioxide). The lungs are located right under the carapace and the vertebral column.
Do sea turtles have teeth?
Sea turtles do not have teeth to grasp their prey with, but instead, have very sharp beaks and strong jaws they use to crush their food.
Do green sea turtles have gills or lungs?
Sea turtles are air-breathing reptiles that have lungs, so they regularly surface to breathe.
Sea turtles spend a majority of their time underwater, so they must be able to hold their breath for long periods.
Their large lungs permit rapid exchange of oxygen and avoid trapping gases during deep dives.
How long can a whale stay underwater?
Whales can hold their breath for a very long time, and this ranges species to species. The average whale can hold its breath for about 60 minutes. The Sperm whale can hold its breath longer than the average whale, for about 90 minutes.
How long can a sea turtle live?
What we do know is that sea turtles live a long time (some can live up to 50 years or more) and have similar lifespans to humans. Most marine turtles take decades to mature—between 20 and 30 years—and remain actively reproductive for another 10 years.
How long can a human hold their breath for?
The longest instance of someone holding their breath without inhaling pure oxygen beforehand is 11 minutes and 34 seconds. However, most people can only safely hold their breath for 1 to 2 minutes.
